Merge tag 'extcon-next-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next
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>;
+ };
