I don't think this is right. Looking at device tree, regulator-5 is using main_gpio0 31 to control SD ENA with PMIC. Which is GPMC0_CLK (N22 pad) and VSEL_SD_SOC. Which is 0x000F407C address in the device datasheet. So as far as I can see, the original address is correct and just the (M19) name is wrong. Did you test this patch to see if that fixed the failure? ~ Judith
