[PATCH 5/5] ARM: dts: cm-t335: add support for bluetooth

2015-12-13 Thread Uri Mashiach 
bluetooth HW is WLS1271 chip connected to UART1.

Device tree modifications:
- Pinmux for UART1.
- Pinmux for bluetooth enable GPIO.

Bluetooth enable GPIO is set to enable during startup by setting the
relevant pinmux pin to pull-up.

[PATCH v2 0/3] regulator: TPS65917/palmas: Add bypass enabling/disabling support

2015-12-13 Thread Keerthy 
ldo9 in palmas/tps659038 and ldo1,ldo2 in tps65917 have bypass
capability. Adding the ops for the same.

Boot tested on DRA7-EVM and DRA72-EVM.

[PATCH v2 1/3] regulator: tps65917/palmas: Add bypass ops for LDOs with bypass capability

2015-12-13 Thread Keerthy 
set/get_bypass ops were missing for ldo1/ldo2 on tps65917 and
ldo9 on palmas/tps659038 which support bypass mode.
Adding the bypass ops helps consumers configure these ldos in
bypass mode or remove bypass mode if need be.

Changes in v2:

 * Added palmas/tps659038 ldo9 bypass ops.
