Are you sure that these USDHC controllers are compatible with i.MX 7D? Could they really run with fsl,imx7d-usdhc compatible? The implementation (Linux kernel driver) is different, I guess on purpose...

AFAIK uSDHC on QXP is derived from the former platforms with adding a few more new features. e.g. HS400ES/CMDQ. Let me loop in uSDHC driver owner Haibo Chen to double confirm.

Haibo, As Krzysztof is helping fix uSDHC binding doc in Patch 12/22, please double check with IC for the whole uSDHC derive relationships on i.MX and feedback to Krzysztof if anything is wrong.

Yes, usdhc of imx8qxp can work by using the compatible "fsl, imx7d-usdhc", but will not support HS400ES/Command Queue any more. Also imx8qxp support Auto CMD23, but imx7d not.

Also imx8qxp support Auto CMD23, but imx7d not. > And imx8qxp need to re-config the clock rate after system PM, imx7d do not need to do this. Then we can leave the compatible in DTS and I will correct the device tree schema. Best regards, Krzysztof

The USDHC on i.MX 8QXP has its own compatible described in bindings and used in the driver (with its own quirks). Remove additional fsl,imx7d-usdhc compatible to fix dtbs_check warnings like: arch/arm64/boot/dts/freescale/imx8qxp-ai_ml.dt.yaml: mmc@5b010000: compatible: ['fsl,imx8qxp-usdhc', 'fsl,imx7d-usdhc'] is too long From schema: /ocumentation/devicetree/bindings/mmc/fsl-imx-esdhc.yaml arch/arm64/boot/dts/freescale/imx8qxp-ai_ml.dt.yaml: mmc@5b010000: compatible: Additional items are not allowed ('fsl,imx7d-usdhc' was unexpected) Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> --- arch/arm64/boot/dts/freescale/imx8qxp.dtsi | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-)
