soc: mediatek: PMIC wrap: Fix possible NULL derefrence.

2017-05-15T08:47:25+00:00

of_match_device could return NULL, and so can cause a NULL
pointer dereference later.

soc: mediatek: PMIC wrap: Fix error handling

2017-05-15T08:47:25+00:00

According to error handling in this function, it is likely that going to
'err_out2' was expected here.

soc: mediatek: avoid using fixed spm power status defines

2017-05-15T08:47:24+00:00

Use variables to replace fixed defines since the offset
of the status of spm power might be different for some chips

soc: mediatek: Add MT2701 scpsys driver

2016-10-30T23:58:58+00:00

Add scpsys driver for MT2701.

mtk-scpsys now supports MT8173 (arm64) and MT2701 (arm). So it should
be enabled on both arm64 and arm platforms.

soc: mediatek: PMIC wrap: Extend the waiting time to 10ms.

2016-08-22T17:31:36+00:00

Read data fails sometimes because of a timeout that PMIC cannot transfer data
to PMIC wrap on time, extend the waiting time to 10ms to reduce the failed
rate.

soc: mtk-pmic-wrap: avoid integer overflow warning

2016-05-19T13:20:24+00:00

On ARM64, the mtk-pmic-wrap driver causes a harmless warning:

mtk-pmic-wrap.c:1062:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
mtk-pmic-wrap.c:1074:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
mtk-pmic-wrap.c:1086:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
  .int_en_all = ~(BIT(31) | BIT(1)),

The problem is that the result of the BIT() macro is an 'unsigned long',
so taking the bitwise NOT operation of that results in an integer
with the upper 32 bits all set and that cannot be assigned to a
'u32' variable without loss of information.

This is harmless because we were never interested in the upper bits
here anyway, so we can shut up the warning by adding a simple cast
to 'u32'.

Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2016-05-18T20:14:02+00:00

Pull ARM SoC driver updates from Arnd Bergmann:
 "Driver updates for ARM SoCs, these contain various things that touch
  the drivers/ directory but got merged through arm-soc for practical
  reasons.

  For the most part, this is now related to power management
  controllers, which have not yet been abstracted into a separate
  subsystem, and typically require some code in drivers/soc or arch/arm
  to control the power domains.

  Another large chunk here is a rework of the NVIDIA Tegra USB3.0
  support, which was surprisingly tricky and took a long time to get
  done.

  Finally, reset controller handling as always gets merged through here
  as well"
