[ 0.257415] pinctrl-s700 e01b0000.pinctrl: can't request region for resource [mem 0xe01b0000-0xe01b0fff] [ 0.266902] pinctrl-s700: probe of e01b0000.pinctrl failed with error -16 This is due to the fact that memory range for "sps" power domain controller clashes with pinctrl. One way to fix it, is to limit pinctrl address range which is safe to do as current pinctrl driver uses address range only up to 0x100. This commit limits the pinctrl address range to 0x100 so that it doesn't conflict with sps range.
