ARM: dts: dra7-evm: pinmuxing updates
v2 cover ARM: dts: dra7-evm: pinmuxing updates
Hi,
This patch series drops most of the pinmuxing from dra7-evm to satisfy erratum i869 and adds missing eMMC and SD card pinmuxing.
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

PATCH v2 1/3 ARM: dts: dra7-evm: Remove pinmux configurations for erratum i869
Pinmuxing for DRA7x/AM57x family of processors need to be done in IO isolation as part of initial bootloader executed from SRAM. This is done as part of iodelay configuration sequence and is required due to the limitations introduced by erratum ID: i869[1] (IO Glitches can occur when changing IO settings) and elaborated in the Technical Reference Manual[2] 18.4.6.1.7 Isolation Requirements.
Only peripheral that is permitted for dynamic pin mux configuration is MMC and DCAN. MMC is permitted to change to accommodate the requirements for varied speeds (which require IO-delay support in kernel as well). DCAN is a result of i893[1] (DCAN initialization sequence).
DCAN pinmux is retained in this patch. MMC pinmux is missing from the dra7-evm.dts file and the board is relying on configuration done by bootloader. A subsequent patch will add MMC pinmux configuration.
A side-effect of this patch is that NAND support is removed. NAND pins clash with VOUT3 on DRA7-EVM. U-Boot selects VOUT3 over NAND as per TI EVM application needs.

PATCH v2 2/3 ARM: dts: dra7-evm: add pinmux configuration for mmc1/2
In reply to Sekhar NoriFrom: Kishon Vijay Abraham I <[email protected]>
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.

Disable it. Commit 46cfc8945887 ("ARM: dts: dra72-evm: Remove pinmux configurations for erratum i869") has already removed pinmuxing for NAND making it unusable.

v2 cover ARM: dts: dra7-evm: pinmuxing updates
In reply to Sekhar NoriQuoted 19 lines · Sekhar Nori
Hi,
This patch series drops most of the pinmuxing from dra7-evm to satisfy erratum i869 and adds missing eMMC and SD card pinmuxing.
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 EVMKishon Vijay Abraham I (1):
