The uniphier-sd controller needs to control some siginals from the SD
interface logic to transition to UHS mode.

This series adds UHS mode support to the controller driver
to refer to and control the interface logic registers, which include
mode selector and SDR speed selector.

Kunihiko Hayashi (5):
  dt-bindings: mmc: uniphier-sd: Add socionext,syscon-uhs-mode property
  mmc: uniphier-sd: Add control of UHS mode using SD interface logic
  mmc: uniphier-sd: Add control to switch UHS speed
  ARM: dts: uniphier: Add syscon-uhs-mode to SD node
  arm64: dts: uniphier: Add syscon-uhs-mode to SD node

Patch 1 to 3 applied for next (I fixed up the comments from Krzysztof
when I applied), thanks!

Kind regards

Thank you for fixing up and applying. I'll send patch 4 and 5 (related to
the devicetree sources) as other requests for the SoC.

Thank you,
