[U-Boot] [PATCH v4 0/9] mmc: sunxi: Enable DM_MMC

[Andre Przywara]

This series gathers all remaining patches we need to enable DM_MMC for
Allwinner boards. It relies on the clock gates framework already merged,
and adds the respective gates and resets for each SoC.
It then teaches the sunxi MMC driver to use the clock framework for
those reset and gates clocks. The "mod clock", responsible for setting
the actual interface speed, is still handled in the MMC driver, as the
DM_CLK part of that is not ready yet (and is not trivial).
This allows to turn on DM_MMC, and gets rid of the doomsday warning
message every Allwinner board was blessed with for a while.

---------------------------

Jagan, can you please have a look whether this is fine? If you are not
sure about patch 7, you can leave this one out for now.
If you are good with it, can you merge it to sunxi/master and send the
PR, so that it still goes into the release?
We can then fix all the remaining issues until the release.

Cheers,
Andre.

Changes in v4:
- Add proper A80 support (special MMC config clock)
- Add V3s support (gates and resets)
- Fix pinmux problem when not booting via SD or eMMC
- smaller fixes per ML discussion
Changes for v3:
- Handle clock via CLK framework.
Changes for v2:
- update the 'reset enablement' logic to do
  required SoC's
