Hello, This series implements support for the MMC core clk-phase-* devicetree bindings in the Aspeed SD/eMMC driver. The relevant register was exposed on the AST2600 and is present for both the SD/MMC controller and the dedicated eMMC controller. There are a couple of prominent changes from v3 in v4 of the series: 1. The devicetree phase parsing helper has been moved to the MMC core 2. KUnit tests have been added for the phase calculations in the ASPEED driver Other than that I've updated MAINTAINERS to add myself as the maintainer of the driver. v3 can be found here: https://lore.kernel.org/linux-mmc/20201123063004.337345-1-andrew@xxxxxxxx/ The series has had light testing on an AST2600-based platform which requires 180deg of input and output clock phase correction at HS200, as well as some synthetic testing under qemu and KUnit. Please review!
