Shawn,

Here's v8 of GPCv2 patches with more feedback from Dong incorporated.

Thanks,
Andrey Smirnov

Changes since v7 (see [v7]):

	- Drop the code to support USB OTG power domains and simplify
          a number of codepaths because of that

	- Add access table to regmap config to prevent accesses to
          undesired locations in the register file

	- Dropped cache type specifier from regmap config

	- Re-arrange constant definition to align more closesly with RM

	- Minor stylistic adjustments

Changes since v6 (see [v6]):

	- Drop .readable_reg related code

	- Switch regmap to REGCACHE_NONE and drop .volatile_reg

	- Remove unnecessary #include directives

Changes since v5 (see [v5]):

	- Apply reverse tree variable declartaion fromatting to
          imx_gpcv2_probe() and imx7_gpc_pu_pgc_sw_pxx_req()

	- Drop patch #3 in favour of defaulting to y in Kconfig
	
Changes since v4 (see [v4]):

	- Single patch is split into multiple as per Shawn's reques

	- Incorporated various feedback from Shawn

Changes since v3 (see [v3]):

	- Minor device tree bindings documentation fixes as per
          feedback from Rob Herring
	- Collect Acked-by from Rob

Changes since v2 (see [v2]):

	- Fix a critical bug where incorrect state of a bit was
          expected in a busy wait loop (bit set instead of bit
          cleared) imx7_gpc_pu_pgc_sw_pxx_req()

	- Add missing step (setting of PCR in GPC_PGC_nCTRL) in power
