Subject: [PATCH v2 0/3] mmc: pwrseq: convert to proper driver

Hi Ulf, 

This patchset aims at converting the pwrseq devices to proper in drivers,
The issue is that on Qualcomm based platforms, most of the gpios require
a pinctrl setup. Existing pwrseq code does not do any kind of pinctrl setup.
So this makes the pwrseq unusable on those platfroms.

Convert the pwrseq to proper drivers so that they can reuse
common driver setup like pinctrl from drivers/base/pinctrl.c and clocks.
This solution works much better and would make pwrseq to reuse 
all the driver setup done in the common code.


Changes sinc v1:
	- Fixed issue while building as module.

Changes since RFC:
	- Fixed issues reported by kbuild test robot.
	- return EPROBE_DEFER from *_alloc() suggested by Ulf.

Thanks,
srini
