Merge tag 'berlin-dt-3.16' of https://github.com/shesselba/linux-berlin into next/dt 

Merge "ARM: berlin: DT changes for v3.16" from Sebastian Hesselbart:

Quite a lot changes but it looks like DT approach is really paying off.
BG2Q joins Berlin SoC family with corresponding development board, DW
gpio nodes for all SoCs. Most notably, we have settled clock bindings
to allow us to continue on drivers requiring clocks and pinctrl bindings.
Last but not least, BG2Q gained SDHCI support and is able to properly
boot into userspace.

* Marvell Berlin2 chip control binding



Marvell Berlin SoCs have a chip control register set providing several

individual registers dealing with pinmux, padmux, clock, reset, and secondary

CPU boot address. Unfortunately, the individual registers are spread among the

chip control registers, so there should be a single DT node only providing the

different functions which are described below.



Required properties:

- compatible: shall be one of

	"marvell,berlin2-chip-ctrl" for BG2

	"marvell,berlin2cd-chip-ctrl" for BG2CD

	"marvell,berlin2q-chip-ctrl" for BG2Q

- reg: address and length of following register sets for

  BG2/BG2CD: chip control register set

  BG2Q: chip control register set and cpu pll registers



* Marvell Berlin2 system control binding



Marvell Berlin SoCs have a system control register set providing several

individual registers dealing with pinmux, padmux, and reset.



Required properties:

- compatible: should be one of

	"marvell,berlin2-system-ctrl" for BG2

	"marvell,berlin2cd-system-ctrl" for BG2CD

	"marvell,berlin2q-system-ctrl" for BG2Q

- reg: address and length of the system control register set



* Clock provider binding



As clock related registers are spread among the chip control registers, the

chip control node also provides the clocks. Marvell Berlin2 (BG2, BG2CD, BG2Q)

SoCs share the same IP for PLLs and clocks, with some minor differences in

features and register layout.



Required properties:

- #clock-cells: shall be set to 1

- clocks: clock specifiers referencing the core clock input clocks

- clock-names: array of strings describing the input clock specifiers above.

    Allowed clock-names for the reference clocks are

      "refclk" for the SoCs osciallator input on all SoCs,

    and SoC-specific input clocks for

      BG2/BG2CD: "video_ext0" for the external video clock input



Clocks provided by core clocks shall be referenced by a clock specifier

indexing one of the provided clocks. Refer to dt-bindings/clock/berlin<soc>.h

for the corresponding index mapping.



* Pin controller binding



Pin control registers are part of both register sets, chip control and system

control. The pins controlled are organized in groups, so no actual pin

information is needed.



A pin-controller node should contain subnodes representing the pin group

configurations, one per function. Each subnode has the group name and the muxing

function used.



Be aware the Marvell Berlin datasheets use the keyword 'mode' for what is called

a 'function' in the pin-controller subsystem.



Required subnode-properties:

- groups: a list of strings describing the group names.

- function: a string describing the function used to mux the groups.



Example:



chip: chip-control@ea0000 {

	compatible = "marvell,berlin2-chip-ctrl";

	#clock-cells = <1>;

	reg = <0xea0000 0x400>;

	clocks = <&refclk>, <&externaldev 0>;

	clock-names = "refclk", "video_ext0";



	spi1_pmux: spi1-pmux {

		groups = "G0";

		function = "spi1";

	};

};



sysctrl: system-controller@d000 {

	compatible = "marvell,berlin2-system-ctrl";

	reg = <0xd000 0x100>;



	uart0_pmux: uart0-pmux {

		groups = "GSM4";

		function = "uart0";

	};



	uart1_pmux: uart1-pmux {

		groups = "GSM5";

		function = "uart1";

	};



	uart2_pmux: uart2-pmux {

		groups = "GSM3";

		function = "uart2";

	};

};
