From: Wolfram Sang <w...@the-dreams.de> This series enables SDHI instances on R-Car Gen3 to access eMMC with 8 bit bus width. I think the patch descriptions speak for themselves.
I decided to not protect this new feature with a flag because it needs specifically to be enabled by setting the bus width to 8. No legacy platform does that. The DTS changes for R-Car Gen3 will come via a seperate series. Note that 'non-removable' is not supported yet because of Runtime PM issues. It seems we need to overhaul Runtime PM handling for other reasons as well, so I suggest the basic support goes in like this and DTS do not use 'non-removable' for now. These patches are based on top of Simon's sdr104-v7 patches but they apply to current mmc/next as well.
