[PATCH v4 0/5] Add a new RTC driver for recent mvebu SoCs

[Gregory CLEMENT]

Hi,

The Marvell Armada 38x SoCs contains an RTC which differs from the RTC
used in the other mvebu SoCs until now. This forth version of the
patch set adds support for this new IP and enable it in the Device
Tree of the Armada 38x SoC.

Thanks,

Grégory

Changelog

v3 -> v4:

- Formatted the device tree binding documentation in a better way
- Renamed the soc-int regmap to rtc-soc because this group of register
  was not only about the interrupt.
- Fixed the rtc_delayed_write function. I found the exact description
  of the WA to use, and the wait should really be after the write.

v2 -> v3:

- Fixed the reg-names description in the dt binding documentation
- Used the delayed version of the writel in everyplace.

v1 -> v2:

- Used reg-names to identify the registers in the device tree
- Changed the space into tab in the MAINTAINERS file
- Emphasized that the 5s wait was only needed between two consecutive
  writes
- Reduced the wait in the set_time function, 100ms were enough
- If no interrupt was available, then disable the alarm related
  functions
- Fixed the critical sections
- Updated the mvebu_v7_defconfig by enabling the new RTC support
