The pcie pinctrl override added in the commita76aa6ffa6("rockchip: rk3568-rock-3a: Enable PCIe and NVMe support") is causing a pinmux issue on linux when using a EFI boot flow. The pcie reset-gpios must however be configured with gpio function, or the device will freeze running pci enum and nothing is connected. Adjust the pinctrl override in u-boot.dtsi to fix this issue. PCIe/NVMe continues to work in both U-Boot and linux after this change. Also revert disable of sdmmc2 and uart1 to fix use of wifi in linux when using a EFI boot flow. Fixes:a76aa6ffa6("rockchip: rk3568-rock-3a: Enable PCIe and NVMe support") Fixes:073d911ae6("rockchip: rk3568-rock-3a: Sync device tree from linux") Signed-off-by: Jonas Karlman <jonas@kwiboo.se>
