Cubietruck AXP20x-regulator

[David Jones]

Notes on Cubietruck Rawhide and Fedora 21 3.16.0-0.rc7.git4.1.fc22.armv7hl

I have noticed that mfd core driver for the X-Powers AXP202 and AXP209, 
axp20x-regulator driver is not being included for the cubietruck.

The option is listed in arch/arm/configs/sunxi_defconfig but I believe 
this option CONFIG_MFD_AXP20X is not listed in any of the following

config-arm-generic

config-armv7
config-armv7-generic

config-armv7-lpae

This mentioned in /drivers/regulator/Kconfig
config REGULATOR_AXP20X
tristate "X-POWERS AXP20X PMIC Regulators"
depends on MFD_AXP20X
help
This driver provides support for the voltage regulators on the AXP20X PMIC.

And also in drivers/mfd/Kconfig

config MFD_AXP20X
bool "X-Powers AXP20X"
select MFD_CORE
select REGMAP_I2C
select REGMAP_IRQ
depends on I2C=y
help
If you say Y here you get support for the X-Powers AXP202 and AXP209.
This driver include only the core APIs. You have to select individual
components like regulators or the PEK (Power Enable Key) under the
corresponding menus.

Another area of concern is the sunxi clock found in

drivers/clk/sunxi/clk-sunxi.c

this is not listed in either in /drivers/clk/Kconfig or /drivers/clk/sunxi/Kconfig(not in directory)

Sorry for being vague with the clk-sunxi, did some research around 3.16.0-0.rc2.git1.1.fc22.armv7hl

The regulator should be enabled in 3.16.0 GA, I picked that issue up last
week. Feedback welcome if the exact config needs to be tweaked (from men
its currently all modules).

As for the clk configs they're normally selected when the SoC is enabled
if, I'll cross check in case there's something that's not.

Thanks for the feedback.

Would this also apply to Cubieboard2?
