[PATCH 00/10] i2c: designware-platdrv: Some improvments related to PM

[ulf.hansson@linaro.org (Ulf Hansson)]

Here's a couple changes for the i2c-designware driver. Most of them a related to
the support for runtime PM and system PM, but there's also a few that improves
some error handling.

I have tested these on Hisilicon Linaro 96-board (hi6220). I used a couple local
changes to enable the power-key to act as a wakeup in system PM suspend state.
If anyone are interested about those as well, I am happy to share them.

Ulf Hansson (10):
  i2c: designware-platdrv: Return error in ->probe() when clk ungate
    fails
  i2c: designware-platdrv: Gate clk in error path in ->probe()
  i2c: designware-platdrv: Unconditionally enable runtime PM
  i2c: designware-platdrv: Disable autosuspend in error path in
    ->probe()
  i2c: designware-platdrv: Fix clk gating in ->remove()
  i2c: designware-platdrv: Update runtime PM last busy mark in ->probe()
  i2c: designware-platdrv: Re-init the HW when resuming
  i2c: designware-platdrv: Check return value from clk_prepare_enable()
  i2c: designware-platdrv: Simplify code by using dev_get_drvdata()
  i2c: designware-platdrv: Rework system PM support
