[PATCH v2 0/3] Allwinner H6 MMC support

[PATCH v2 0/3] Allwinner H6 MMC support

[Icenowy Zheng]

This patchset adds support for MMC controller in the Allwinner H6 SoC.

Its function is a superset of the A64 MMC controller's, so it currently
use A64 compatible as a fallback.

  dt-binding: mmc: sunxi: add H6 compatible (with A64 fallback)
  arm64: allwinner: h6: add device tree nodes for MMC controllers
  arm64: allwinner: h6: enable MMC0/2 on Pine H64

[PATCH v2 1/3] dt-binding: mmc: sunxi: add H6 compatible (with A64 fallback)

[Icenowy Zheng]

The MMC controllers on H6 is similar to the ones on A64, but with some
new features.

Add compatible strings for them (with the A64 compatible strings as
fallback, in order to make them to work with A64 drivers).
