[PATCH v7 0/3] phy: intel: Add Keem Bay eMMC PHY support

[Wan Ahmad Zainie]

Hi.

The first patch is new and added to rename rename
phy-intel-{combo,emmc}.c to phy-intel-lgm-{combo,emmc}.c..

The second patch is to document DT bindings for Keem Bay eMMC PHY.

The the third 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
