From: Wolfram Sang <w...@the-dreams.de> Here are the DTS changes to enable the on-board eMMC memory at 8 bit bus widths on R-Car Gen3 Salvator-X boards.
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. Note also that I decided to use the pattern that pinctrl-0 is 3.3v and pinctrl-1 is 1.8v, although the eMMC is fixed at 1.8v. I tried a few ways to only use pinctrl-0 being 1.8v here, but they all ended up to be confusing for users IMO, so I sticked to the most consistent solution after all. These patches are based on top of Simon's sdr104-v7 patches and the accompanied driver patches sent a minute ago.
