Because of fundamental interface issues in am65x pg1, only the initial sdhci1 node at 25 MHz was added in the u-boot.dtsi from which both the base-board.dts and r5-base-board.dts inherit the node. Move the node out to k3-am65-main.dtsi where it belongs and add the board specific properties in base-board.dts and r5-base-board.dts This ensures dts compatibility with the kernel dts in the base-board.dts and enables the SD card interface at 50 MHz and High Speed mode While we are here, also fix the main_mmc0_pins_default property to be included and inherit from the base-board.dts instead of the u-boot.dtsi Signed-off-by: Faiz Abbas <faiz_abbas@ti.com> Signed-off-by: Aswath Govindraju <a-govindraju@ti.com>
