If that may help, we are going to upstream it (need > some rework after rebasing from 11.x). From a quick look at Linux, should be very similar. LX2160 uses just "fsl,esdhc" which is handled by the same driver as "fsl,ls1046a-esdhc" but w/o any specific clock data. https://github.com/torvalds/linux/blob/master/drivers/mmc/host/sdhci-of-esdhc.c https://github.com/SolidRun/edk2-platforms/blob/eec706c2d693be0b3793d9180e7d1a4813a526cf/Silicon/NXP/LX2160A/Include/DeviceTreeInclude/fsl-lx2160a.dtsi#L364-L387 The changes you're going to upstream, are they for fsl_sdhci or generic sdhci?help
