Subject: [PATCH V3 1/3] dt-bindings: mmc: imx-esdhc: Update compatible fallbacks
Date: Sat, 2 Apr 2022 14:39:39 -0500 [thread overview]
Message-ID: <20220402193942.744737-2-aford173@gmail.com> (raw)
In-Reply-To: <20220402193942.744737-1-aford173@gmail.com>
The SDHC controller in the imx8mn and imx8mp have the same controller
as the imx8mm which is slightly different than that of the imx7d.
Using the fallback of the imx8mm enables the controllers to support
HS400-ES which is not available on the imx7d. After discussion with NXP,
it turns out that the imx8qm should fall back to the imx8qxp, because
those have some additional flags not present in the imx8mm.

V3: Marked the imx7d-usdhc as deprecated when there are better
fallback options or the fallback isn't needed.
Leave the deprecated fallback in the YAML to prevent errors
Remove Reviewed-by from Krzysztof Kozlowski due to the above
V2: Update the table per recomendation from Haibo.
