[PATCH v8 00/13] Add Maxim 77802 PMIC support

[Javier Martinez Canillas <javier.martinez@collabora.co.uk>]

This series are based on drivers added by Simon Glass to the Chrome OS
kernel and adds support for the Maxim 77802 Power Management IC, their
regulators, clocks, RTC and i2c interface.

This is a v8 of the patch-set that addresses issues pointed out in v7.
Individual changes are added on each patch but the biggest changes are:

* Patches 1-7 from v7 are not included since those were improvements to
the max77686 mfd driver and can be applied independently. Lee Jones said
that he is going to pick them from the posted v7 series.

I've created a patchwork bundle with 1-7 from v7 to make it easy to apply:

https://patchwork.kernel.org/bundle/javier/max77686-improvements/

* The Dynamic Voltage Scaling support has been removed since that can be
added in a follow up series and shouldn't block the minimum PMIC support.

The patch-set has been tested on both Daisy/Snow (max77686) and Peach
Pit (max77802) Chromebooks and it's composed of the following patches:

[PATCH v8 01/13] mfd: max77686: Add Maxim 77802 PMIC support
[PATCH v8 02/13] mfd: max77802: Add DT binding documentation
[PATCH v8 03/13] regulator: Add driver for Maxim 77802 PMIC regulators
[PATCH v8 04/13] clk: max77686: Add DT include for MAX77686 PMIC clock
[PATCH v8 05/13] clk: Add generic driver for Maxim PMIC clocks
[PATCH v8 06/13] clk: max77686: Convert to the generic max clock driver
[PATCH v8 07/13] clk: max77686: Improve Maxim 77686 PMIC clocks binding
[PATCH v8 08/13] clk: Add driver for Maxim 77802 PMIC clocks
[PATCH v8 09/13] clk: max77802: Add DT binding documentation
[PATCH v8 10/13] rtc: max77686: Allow the max77686 rtc to wakeup the system
[PATCH v8 11/13] rtc: max77686: Remove dead code for SMPL and WTSR
[PATCH v8 12/13] rtc: Add driver for Maxim 77802 PMIC Real-Time-Clock
[PATCH v8 13/13] ARM: dts: Add max77802 to exynos5420-peach-pit and exynos5800-peach-pi

Patch 01/13 extend the max77686 mfd driver to also support the max77802
PMIC and patch 02/13 adds the DT binding documentation for this PMIC.

Patch 03/13 adds support for the regulators found in the PMIC.

Patch 04/13 to 07/13 are improvements and refactoring to the max77686 clock
driver to avoid code duplication when adding max77802 clocks support in patch
08/13. Patch 09/13 adds the DT binding document for the max77802 clock driver.

Patches 10/13 and 11/13 are improvements to max77686 RTC driver and patch
12/13 adds support for the RTC found in the max77802 PMIC.

Finally patch 13/13 adds the required device node to the Peach Pit and Pi
exynos5 based boards.

Since there are cross-subsystems dependencies, I think that the best way to
sort this out is if relevant maintainers ack the patches so 01/13 to 012/13
can be merged through the mfd tree. The patches and the relevant acks are:

Patch 03/13 (regulator - Mark Brown)
Patches 04/13 to 09/13 (clk - Mike Turquette)
Patches 10/13 to 12/13 (rtc - Alessandro Zummo)

Patch 13/13 is only a DTS change so it can be picked by Kukjin Kim once the
other patches are picked by Lee Jones.

Since we are in 3.16-rc5 already, it would be great if I can get your acks
or feedback since I was hoping this series to make it to 3.17. This is due
other series that were already posted depend on this one.

Also, the series have been reviewed and tested by Samsung folks and most of
the patches already collected Reviewed-by and Tested-by tags.

Thanks a lot and best regards,
Javier
