[PATCH v3 0/6] ARM: sunxi: RTC support for A31/A23

[Chen-Yu Tsai]

Hi everyone,

This is v3 of the sun6i RTC series. This series adds support for
the RTC in A31 and A23 SoCs. The series applies to sunxi-next.

The A31 has a new RTC block that is separate from the timer block.
It has separate interrupts for each of the alarms, and a different
format for the counter alarm. The driver has been tested on the
A31 Hummingbird, and the A23 tablet I'm using to work on sun8i
support.

Patch 1 adds the driver for the RTC.

Patch 2 is a minor cleanup. This makes rtc-sunxi depend on sun4i or
sun7i, the 2 platforms the driver is actually used on.

Patch 3 adds the RTC device node to the sun6i DTSI.

Patch 4 adds the RTC device node to the sun8i DTSI.

Patch 5 adds enables rtc-sun6i in the sunxi defconfig.

Patch 6 adds enables rtc-sun6i in the multi_v7 defconfig.
This patch applies to arm-soc/next/defconfig (e9a86d96)

Changes since v2:
  - fixed indentation in DT binding docs
  - have function argument indentation match open parenthesis
  - drop driver owner field

Changes since v1:
  - Enable rtc-sun6i in multi_v7_defconfig
  - Cleanup the time/date GET/SET macros
  - Use GENMASK for control register mask
  - Change Kconfig option to show 'A31'
  - Remove leftover comment from rtc-sun4i
  - Remove extra newline


Cheers
ChenYu
