Hi. The first part is to document DT bindings for Keem Bay eMMC PHY.
The second is the driver file, loosely based on phy-rockchip-emmc.c and phy-intel-emmc.c. The latter is not being reused as there are quite a number of differences i.e. registers offset, supported clock rates, bitfield to set. The patch was tested with Keem Bay evaluation module board. Thank you. Best regards, Zainie Changes since v3: - Exit keembay_emmc_phy_power() with return ret;. - In keembay_emmc_phy_init(), use PTR_ERR_OR_ZERO(...). - In keembay_emmc_phy_probe(), devm_regmap_init_mmio(...) in single line. Changes since v2: - Modify DT example to use single cell for address and size. Changes since v1: - Rework phy-keembay-emmc.c to make it similar to phy-intel-emmc.c. - Use regmap_mmio, and remove reference to intel,syscon. - Use node name phy@.... - Update license i.e. use dual license.
