This series enables the Allwinner MMC driver to drive all SoCs with its DM_MMC variant. We use the gates clock and reset support from the new clock driver, but keep the actual mod clock in its somewhat hackish state. Properly supporting this via the clock driver is a bit more work. The per-compatible variant struct for now only holds the mod clock address (which will go away), but we will need the struct later again for the various timing modes.
This allows us to eventually enable DM_MMC for all SoCs, and get rid of the nasty deprecation warning.
The first patch adds the MMC clock gates and resets to the clock driver. Patch 2/9 adds support for the A80 MMC config clock, which is a bit special. I can't test this, so please give this a try if you have a board.
Patch 3 uses the new clocks in the MMC driver, the following three patches add the remaining compatible strings along with their required mod clock addresses.
Patch 7 fixes the Pine64-LTS board, while patch 8 eventually enables everything. Patch 9 is some comment fix to make it easier to reason about what part of the driver is for DM_MMC and which is not.
I successfully compiled the HEAD for all 142 Allwinner boards, also compiled all patches for selected boards.
This was briefly tested on Pine-H64 (H6), Pine64-LTS (A64), OrangePi PC 2 (H5), OrangePi Zero (H2+) and BananaPi-M1 (A20).
Please run it on every board that you can get hold of to give this series a good shake.
This goes on top of current sunxi/master (543049ab5906) and is available on https://github.com/apritzel/u-boot/commits/sunxi-dm.
This replaces Jagan's v2 series "mmc: sunxi: Enable DM_MMC" in a more driver model compliant way, borrowing two patches from him.
Cheers, Andre.
