The relevant register was exposed on the AST2600 and is present for both the SD/MMC controller and the dedicated eMMC controller. v6 simply removes the typedef from v5 in favour of a struct containing the phase array. I've just done a quick build test of v6 given the small change and more extensive testing done with v5. v5 can be found here: https://lore.kernel.org/linux-mmc/20201208012615.2717412-1-andrew@aj.id.au/ Please review!
