[PATCH v3 1/2] arm64: dts: ti: k3-am62p/j722s: Remove HS400 support from common
Posted by Judith Mendez 5 months ago 
Since eMMC HS400 has been descoped for J722s due to errata i2478 [0]
and is supported for AM62Px device, remove eMMC HS400 support from
common-main.dtsi and include only in am62p-main.dtsi.
