Subject: [PATCH v4 0/2] phy: intel: Add Keem Bay eMMC PHY support

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.
