From 6c1757be927ab1800754b14df01ad56da795339a Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Sun, 10 Apr 2022 14:35:41 -0500 Subject: [PATCH] dt-bindings: mmc: imx-esdhc: Update compatible fallbacks 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. Mark the current state of the fallbacks as deprecated, and add the proper fallbacks so in the future, the deprecated combination can be removed and prevent any future devices from using the wrong fallback.
