The patches apply to latest linux-next. Tested on DRA74x EVM Rev H using U-Boot 2016.11. Boot tested using NFS and basic testing carried out on SD card, eMMC, Audio capture and playback.

* [PATCH 2/2] ARM: dts: dra7-evm: add pinmux configuration for mmc1/2 @ 2016-11-29 9:24 ` Sekhar Nori 0 siblings, 0 replies; 8+ messages in thread From: Sekhar Nori @ 2016-11-29 9:24 UTC (permalink / raw) To: linux-arm-kernel From: Kishon Vijay Abraham I <kishon@ti.com> Add pinmux configuration for SD card slot and eMMC device found on TI's DRA74x EVM. Only the default modes are supported. For higher speed modes (UHS and HS200) to function, we need full fledged IODelay support in kernel. IODelay support is yet to be added.
