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. NAND on DRA72 EVM is already unusable due to a similar patch. A patch included here disables the GPMC node. v1 -> v2: - Add a patch to disable GPMC node on DRA72x EVM - Disable GPMC node on DRA74x EVM Kishon Vijay Abraham I (1): ARM: dts: dra7-evm: add pinmux configuration for mmc1/2 Sekhar Nori (2): ARM: dts: dra7-evm: Remove pinmux configurations for erratum i869 ARM: dts: dra72-evm: drop NAND support arch/arm/boot/dts/dra7-evm.dts | 282 ++++---------------------------- arch/arm/boot/dts/dra72-evm-common.dtsi | 7 +- 2 files changed, 35 insertions(+), 254 deletions(-) -- 2.9.0 ^ permalink raw reply [flat|nested] 10+ messages in thread

* [PATCH v2 2/3] ARM: dts: dra7-evm: add pinmux configuration for mmc1/2 @ 2016-12-13 11:29 ` Sekhar Nori 0 siblings, 0 replies; 10+ messages in thread From: Sekhar Nori @ 2016-12-13 11:29 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.
