This series ports some of the patches from fsl_esdhc to fsl_esdhc_imx. Because these drivers share a common lineage, many of these patches apply with minor changes. For each one, I have noted the originating commit in the style of linux stable backports.
In fa33d20749 ("mmc: split fsl_esdhc driver for i.MX"), Yangbo says
For the two series processors, the eSDHCs are becoming more and more different
However, these drivers are still extremely similar; the differences between them are not major. However, NXP has not done a good job of porting patches which apply to both drivers. This causes the fsl_esdhc_imx driver to rot, as the fsl_esdhc gets more general fixes. For this reason, I think that the fsl_esdhc_imx driver should be removed unless NXP can commit to creating series like this which port patches which apply to both drivers.
