[PATCH v2 0/2] Remove HS400 support from common

Posted by Judith Mendez 1 day, 3 hours ago

Since eMMC HS400 has been descoped for j722s due to errata i2478 [0]
and is supported by default for AM62Px device, remove sdhci0 node from
common-main.dtsi and include instead only for AM62Px in am62p-main.dtsi.

Also, update the STRB value for am62p eMMC sdhci0 node.

Tested on am62p SK board.

- Keep the common node and only remove hs400 support from the common
  node. Enable instead HS400 support only for AM62Px in am62p-main.dtsi.
