Chanwoo writes:

Update extcon for v3.17

This patchset add new extcon provider driver and fix minor issue of extcon driver.

Detailed description for patchset:
1. Add new Silicon-Mitus SM5502 MUIC (Micro-USB Interface Controller) device
- extcon-sm5502 driver  is capable of identifying the type of the external power
source and attached accessory. And external power sources, such as Dedicated
charger or a standard USB port, are able to charge the battery in the smart
phone via the connector.

2. Fix minor issue of extcon driver
- extcon-arizona driver
- extcon-palmas driver
- Remove unnecessary OOM messages for all extcon device drivers

3. Fix minor issue of extcon core
- Re-order the sequence of extcon device driver in Kconfig/Makefile alphabitically
- Set parent device of extcon device automatically using devm_extcon_dev_allocate()

4. Fix MAX77693 driver
- This patchset has dependency on MFD/Regulator/Extcon. So, Lee Jones
(MFD Maintainer) created Immutable branch between MFD and Extcon due
for v3.17 merge-window and then I merged this patchset from MFD git repo[1]
to Extcon git repo.

* SM5502 MUIC (Micro-USB Interface Controller) device



The Silicon Mitus SM5502 is a MUIC (Micro-USB Interface Controller) device

which can detect the state of external accessory when external accessory is

attached or detached and button is pressed or released. It is interfaced to

the host controller using an I2C interface.



Required properties:

- compatible: Should be "siliconmitus,sm5502-muic"

- reg: Specifies the I2C slave address of the MUIC block. It should be 0x25

- interrupt-parent: Specifies the phandle of the interrupt controller to which

  the interrupts from sm5502 are delivered to.

- interrupts: Interrupt specifiers for detection interrupt sources.



Example:



	sm5502@25 {

		compatible = "siliconmitus,sm5502-muic";

		interrupt-parent = <&gpx1>;

		interrupts = <5 0>;

		reg = <0x25>;

	};
