[PATCH] mmc: sdhci_am654: Add Support for TI's AM62 SoC

[PATCH] mmc: sdhci_am654: Add Support for TI's AM62 SoC

[Aswath Govindraju]

Add support for the controller present on the AM62x SoC.

There are instances:
sdhci0: 8bit bus width, max 200 MBps
sdhci1: 4bit bus width, max 100 MBps
sdhci2: 4bit bus width, max 100 MBps

The PHY used for 8 bit instance is same as the PHY for the 4 bit instance.
Therefore, introduce a new bus width independent compatible for AM62 SoC
that uses the driver data required for 4 bit instance.

Applied for next, thanks!
