Naming conventions

------------------

For mpc5200 on-chip devices, the format for each compatible value is

<chip>-<device>[-<mode>].  The OS should be able to match a device driver

to the device based solely on the compatible value.  If two drivers

match on the compatible list; the 'most compatible' driver should be

selected.

The split between the MPC5200 and the MPC5200B leaves a bit of a

conundrum.  How should the compatible property be set up to provide

maximum compatibility information; but still accurately describe the

chip?  For the MPC5200; the answer is easy.  Most of the SoC devices

originally appeared on the MPC5200.  Since they didn't exist anywhere

else; the 5200 compatible properties will contain only one item;

"fsl,mpc5200-<device>".

The 5200B is almost the same as the 5200, but not quite.  It fixes

silicon bugs and it adds a small number of enhancements.  Most of the

devices either provide exactly the same interface as on the 5200.  A few

devices have extra functions but still have a backwards compatible mode.

To express this information as completely as possible, 5200B device trees

should have two items in the compatible list:

	compatible = "fsl,mpc5200b-<device>","fsl,mpc5200-<device>";

It is *strongly* recommended that 5200B device trees follow this convention

(instead of only listing the base mpc5200 item).

ie. ethernet on mpc5200: compatible = "fsl,mpc5200-fec";

    ethernet on mpc5200b: compatible = "fsl,mpc5200b-fec", "fsl,mpc5200-fec";

Modal devices, like PSCs, also append the configured function to the

end of the compatible field.  ie. A PSC in i2s mode would specify

"fsl,mpc5200-psc-i2s", not "fsl,mpc5200-i2s".  This convention is chosen to

avoid naming conflicts with non-psc devices providing the same

function.  For example, "fsl,mpc5200-spi" and "fsl,mpc5200-psc-spi" describe

the mpc5200 simple spi device and a PSC spi mode respectively.

At the time of writing, exact chip may be either 'fsl,mpc5200' or

'fsl,mpc5200b'.

The soc node

------------

This node describes the on chip SOC peripherals.  Every mpc5200 based

board will have this node, and as such there is a common naming

convention for SOC devices.

Required properties:

name			description

----			-----------

ranges			Memory range of the internal memory mapped registers.

			Should be <0 [baseaddr] 0xc000>

reg			Should be <[baseaddr] 0x100>

compatible		mpc5200: "fsl,mpc5200-immr"

			mpc5200b: "fsl,mpc5200b-immr"

system-frequency	'fsystem' frequency in Hz; XLB, IPB, USB and PCI

			clocks are derived from the fsystem clock.

bus-frequency		IPB bus frequency in Hz.  Clock rate

			used by most of the soc devices.

soc child nodes

---------------

Any on chip SOC devices available to Linux must appear as soc5200 child nodes.

Note: The tables below show the value for the mpc5200.  A mpc5200b device

tree should use the "fsl,mpc5200b-<device>","fsl,mpc5200-<device>" form.

Required soc5200 child nodes:

name				compatible		Description

----				----------		-----------

cdm@<addr>			fsl,mpc5200-cdm		Clock Distribution

interrupt-controller@<addr>	fsl,mpc5200-pic		need an interrupt

irda@<addr>	fsl,mpc5200-psc-irda	 PSC in IrDA mode

spi@<addr>	fsl,mpc5200-spi		 MPC5200 spi device

ethernet@<addr>	fsl,mpc5200-fec		 MPC5200 ethernet device

ata@<addr>	fsl,mpc5200-ata		 IDE ATA interface

i2c@<addr>	fsl,mpc5200-i2c		 I2C controller

usb@<addr>	fsl,mpc5200-ohci,ohci-be USB controller

xlb@<addr>	fsl,mpc5200-xlb		 XLB arbitrator

fsl,mpc5200-gpt nodes

---------------------

On the mpc5200 and 5200b, GPT0 has a watchdog timer function.  If the board

design supports the internal wdt, then the device node for GPT0 should

include the empty property 'fsl,has-wdt'.

An mpc5200-gpt can be used as a single line GPIO controller.  To do so,

add the following properties to the gpt node:

	gpio-controller;

	#gpio-cells = <2>;

When referencing the GPIO line from another node, the first cell must always

be zero and the second cell represents the gpio flags and described in the

gpio device tree binding.

An mpc5200-gpt can be used as a single line edge sensitive interrupt

controller.  To do so, add the following properties to the gpt node:

	interrupt-controller;

	#interrupt-cells = <1>;

When referencing the IRQ line from another node, the cell represents the

sense mode; 1 for edge rising, 2 for edge falling.

fsl,mpc5200-psc nodes

---------------------

The PSCs should include a cell-index which is the index of the PSC in

hardware.  cell-index is used to determine which shared SoC registers to

use when setting up PSC clocking.  cell-index number starts at '0'.  ie:

	PSC1 has 'cell-index = <0>'

	PSC4 has 'cell-index = <3>'

PSC in i2s mode:  The mpc5200 and mpc5200b PSCs are not compatible when in

i2s mode.  An 'mpc5200b-psc-i2s' node cannot include 'mpc5200-psc-i2s' in the

compatible field.

fsl,mpc5200-gpio and fsl,mpc5200-gpio-wkup nodes

------------------------------------------------

Each GPIO controller node should have the empty property gpio-controller and

#gpio-cells set to 2. First cell is the GPIO number which is interpreted

according to the bit numbers in the GPIO control registers. The second cell

is for flags which is currently unused.

fsl,mpc5200-fec nodes

---------------------

The FEC node can specify one of the following properties to configure

the MII link:

- fsl,7-wire-mode - An empty property that specifies the link uses 7-wire

                    mode instead of MII

- current-speed   - Specifies that the MII should be configured for a fixed

                    speed.  This property should contain two cells.  The

                    first cell specifies the speed in Mbps and the second

                    should be '0' for half duplex and '1' for full duplex

- phy-handle      - Contains a phandle to an Ethernet PHY.

Interrupt controller (fsl,mpc5200-pic) node

-------------------------------------------

The mpc5200 pic binding splits hardware IRQ numbers into two levels.  The

split reflects the layout of the PIC hardware itself, which groups

interrupts into one of three groups; CRIT, MAIN or PERP.  Also, the

Bestcomm dma engine has it's own set of interrupt sources which are

cascaded off of peripheral interrupt 0, which the driver interprets as a

fourth group, SDMA.

The interrupts property for device nodes using the mpc5200 pic consists

of three cells; <L1 L2 level>

    L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]

    L2 := interrupt number; directly mapped from the value in the

          "ICTL PerStat, MainStat, CritStat Encoded Register"

    level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]

For external IRQs, use the following interrupt property values (how to

specify external interrupts is a frequently asked question):

External interrupts:

	external irq0:	interrupts = <0 0 n>;

	external irq1:	interrupts = <1 1 n>;

	external irq2:	interrupts = <1 2 n>;

	external irq3:	interrupts = <1 3 n>;

'n' is sense (0: level high, 1: edge rising, 2: edge falling 3: level low)

********** DRAFT ***********

I - Introduction

================

Boards supported by the arch/powerpc architecture require device tree be

passed by the boot loader to the kernel at boot time.  The device tree

describes what devices are present on the board and how they are

connected.  The device tree can either be passed as a binary blob (as

described in Documentation/powerpc/booting-without-of.txt), or passed

by Open Firmware (IEEE 1275) compatible firmware using an OF compatible

client interface API.

This document specifies the requirements on the device-tree for mpc5200

based boards.  These requirements are above and beyond the details

specified in either the Open Firmware spec or booting-without-of.txt

All new mpc5200-based boards are expected to match this document.  In

cases where this document is not sufficient to support a new board port,

this document should be updated as part of adding the new board support.

II - Philosophy

===============

The core of this document is naming convention.  The whole point of

defining this convention is to reduce or eliminate the number of

special cases required to support a 5200 board.  If all 5200 boards

follow the same convention, then generic 5200 support code will work

rather than coding special cases for each new board.

This section tries to capture the thought process behind why the naming

convention is what it is.

1.  names

---------

There is strong convention/requirements already established for children

of the root node.  'cpus' describes the processor cores, 'memory'

describes memory, and 'chosen' provides boot configuration.  Other nodes

are added to describe devices attached to the processor local bus.

Following convention already established with other system-on-chip

processors, 5200 device trees should use the name 'soc5200' for the

parent node of on chip devices, and the root node should be its parent.

Child nodes are typically named after the configured function.  ie.

the FEC node is named 'ethernet', and a PSC in uart mode is named 'serial'.

2. device_type property

-----------------------

similar to the node name convention above; the device_type reflects the

configured function of a device.  ie. 'serial' for a uart and 'spi' for

an spi controller.  However, while node names *should* reflect the

configured function, device_type *must* match the configured function

exactly.

3. compatible property

----------------------

Since device_type isn't enough to match devices to drivers, there also

needs to be a naming convention for the compatible property.  Compatible

is an list of device descriptions sorted from specific to generic.  For

the mpc5200, the required format for each compatible value is

<chip>-<device>[-<mode>].  The OS should be able to match a device driver

to the device based solely on the compatible value.  If two drivers

match on the compatible list; the 'most compatible' driver should be

selected.

The split between the MPC5200 and the MPC5200B leaves a bit of a

conundrum.  How should the compatible property be set up to provide

maximum compatibility information; but still accurately describe the

chip?  For the MPC5200; the answer is easy.  Most of the SoC devices

originally appeared on the MPC5200.  Since they didn't exist anywhere

else; the 5200 compatible properties will contain only one item;

"mpc5200-<device>".

The 5200B is almost the same as the 5200, but not quite.  It fixes

silicon bugs and it adds a small number of enhancements.  Most of the

devices either provide exactly the same interface as on the 5200.  A few

devices have extra functions but still have a backwards compatible mode.

To express this information as completely as possible, 5200B device trees

should have two items in the compatible list;

"mpc5200b-<device>\0mpc5200-<device>".  It is *strongly* recommended

that 5200B device trees follow this convention (instead of only listing

the base mpc5200 item).

If another chip appear on the market with one of the mpc5200 SoC

devices, then the compatible list should include mpc5200-<device>.

ie. ethernet on mpc5200: compatible = "mpc5200-ethernet"

    ethernet on mpc5200b: compatible = "mpc5200b-ethernet\0mpc5200-ethernet"

Modal devices, like PSCs, also append the configured function to the

end of the compatible field.  ie. A PSC in i2s mode would specify

"mpc5200-psc-i2s", not "mpc5200-i2s".  This convention is chosen to

avoid naming conflicts with non-psc devices providing the same

function.  For example, "mpc5200-spi" and "mpc5200-psc-spi" describe

the mpc5200 simple spi device and a PSC spi mode respectively.

If the soc device is more generic and present on other SOCs, the

compatible property can specify the more generic device type also.

ie. mscan: compatible = "mpc5200-mscan\0fsl,mscan";

At the time of writing, exact chip may be either 'mpc5200' or

'mpc5200b'.

Device drivers should always try to match as generically as possible.

III - Structure

===============

The device tree for an mpc5200 board follows the structure defined in

booting-without-of.txt with the following additional notes:

0) the root node

----------------

Typical root description node; see booting-without-of

1) The cpus node

----------------

The cpus node follows the basic layout described in booting-without-of.

The bus-frequency property holds the XLB bus frequency

The clock-frequency property holds the core frequency

2) The memory node

------------------

Typical memory description node; see booting-without-of.

3) The soc5200 node

-------------------

This node describes the on chip SOC peripherals.  Every mpc5200 based

board will have this node, and as such there is a common naming

convention for SOC devices.

Required properties:

name			type		description

----			----		-----------

device_type		string		must be "soc"

ranges			int		should be <0 baseaddr baseaddr+10000>

reg			int		must be <baseaddr 10000>

compatible		string		mpc5200: "mpc5200-soc"

					mpc5200b: "mpc5200b-soc\0mpc5200-soc"

system-frequency	int		Fsystem frequency; source of all

					other clocks.

bus-frequency		int		IPB bus frequency in HZ.  Clock rate

					used by most of the soc devices.

#interrupt-cells	int		must be <3>.

Recommended properties:

name			type		description

----			----		-----------

model			string		Exact model of the chip;

					ie: model="fsl,mpc5200"

revision		string		Silicon revision of chip

					ie: revision="M08A"

The 'model' and 'revision' properties are *strongly* recommended.  Having

them presence acts as a bit of a safety net for working around as yet

undiscovered bugs on one version of silicon.  For example, device drivers

can use the model and revision properties to decide if a bug fix should

be turned on.

4) soc5200 child nodes

----------------------

Any on chip SOC devices available to Linux must appear as soc5200 child nodes.

Note: The tables below show the value for the mpc5200.  A mpc5200b device

tree should use the "mpc5200b-<device>\0mpc5200-<device> form.

Required soc5200 child nodes:

name		device_type		compatible	Description

----		-----------		----------	-----------

cdm@<addr>	cdm			mpc5200-cmd	Clock Distribution

pic@<addr>	interrupt-controller	mpc5200-pic	need an interrupt

							controller to boot

bestcomm@<addr>	dma-controller		mpc5200-bestcomm 5200 pic also requires

							 the bestcomm device

Recommended soc5200 child nodes; populate as needed for your board

name		device_type	compatible	  Description

----		-----------	----------	  -----------

gpt@<addr>	gpt		fsl,mpc5200-gpt	  General purpose timers

gpt@<addr>	gpt		fsl,mpc5200-gpt-gpio	General purpose

							timers in GPIO mode

pci@<addr>	pci		mpc5200-pci	  PCI bridge

serial@<addr>	serial		mpc5200-psc-uart  PSC in serial mode

i2s@<addr>	sound		mpc5200-psc-i2s	  PSC in i2s mode

spi@<addr>	spi		mpc5200-psc-spi	  PSC in spi mode

irda@<addr>	irda		mpc5200-psc-irda  PSC in IrDA mode

spi@<addr>	spi		mpc5200-spi	  MPC5200 spi device

ethernet@<addr>	network		mpc5200-fec	  MPC5200 ethernet device

ata@<addr>	ata		mpc5200-ata	  IDE ATA interface

i2c@<addr>	i2c		mpc5200-i2c	  I2C controller

usb@<addr>	usb-ohci-be	mpc5200-ohci,ohci-be	USB controller

xlb@<addr>	xlb		mpc5200-xlb	  XLB arbitrator

Important child node properties

name		type		description

----		----		-----------

cell-index	int		When multiple devices are present, is the

				index of the device in the hardware (ie. There

				are 6 PSC on the 5200 numbered PSC1 to PSC6)

				    PSC1 has 'cell-index = <0>'

				    PSC4 has 'cell-index = <3>'

5) General Purpose Timer nodes (child of soc5200 node)

On the mpc5200 and 5200b, GPT0 has a watchdog timer function.  If the board

design supports the internal wdt, then the device node for GPT0 should

include the empty property 'fsl,has-wdt'.

6) PSC nodes (child of soc5200 node)

PSC nodes can define the optional 'port-number' property to force assignment

order of serial ports.  For example, PSC5 might be physically connected to

the port labeled 'COM1' and PSC1 wired to 'COM1'.  In this case, PSC5 would

have a "port-number = <0>" property, and PSC1 would have "port-number = <1>".

PSC in i2s mode:  The mpc5200 and mpc5200b PSCs are not compatible when in

i2s mode.  An 'mpc5200b-psc-i2s' node cannot include 'mpc5200-psc-i2s' in the

compatible field.

7) GPIO controller nodes

Each GPIO controller node should have the empty property gpio-controller and

#gpio-cells set to 2. First cell is the GPIO number which is interpreted

according to the bit numbers in the GPIO control registers. The second cell

is for flags which is currently unsused.

8) FEC nodes

The FEC node can specify one of the following properties to configure

the MII link:

"fsl,7-wire-mode" - An empty property that specifies the link uses 7-wire

                    mode instead of MII

"current-speed"   - Specifies that the MII should be configured for a fixed

                    speed.  This property should contain two cells.  The

                    first cell specifies the speed in Mbps and the second

                    should be '0' for half duplex and '1' for full duplex

"phy-handle"      - Contains a phandle to an Ethernet PHY.

IV - Extra Notes

================

1. Interrupt mapping

--------------------

The mpc5200 pic driver splits hardware IRQ numbers into two levels.  The

split reflects the layout of the PIC hardware itself, which groups

interrupts into one of three groups; CRIT, MAIN or PERP.  Also, the

Bestcomm dma engine has it's own set of interrupt sources which are

cascaded off of peripheral interrupt 0, which the driver interprets as a

fourth group, SDMA.

The interrupts property for device nodes using the mpc5200 pic consists

of three cells; <L1 L2 level>

    L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]

    L2 := interrupt number; directly mapped from the value in the

          "ICTL PerStat, MainStat, CritStat Encoded Register"

    level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]

2. Shared registers

-------------------

Some SoC devices share registers between them.  ie. the i2c devices use

a single clock control register, and almost all device are affected by

the port_config register.  Devices which need to manipulate shared regs

should look to the parent SoC node.  The soc node is responsible

for arbitrating all shared register access.
