The M.2 connector on this board can operate in both PCIe and SDIO modes, and SDIO-based WLAN modules require proper power control through the same M.2 WLAN enable line (W_DISABLE1 on pin 56). The first two patches are preparation changes: - Patch 1 corrects the IOMUX configuration by enabling the pull-select bit for the M.2 regulator GPIO, ensuring that the weak pull-up is actually applied. - Patch 2 renames the regulator node from reg_pcie0 to reg_m2_wlan so that the same GPIO-controlled power rail can be cleanly reused by both PCIe- and SDIO-based WLAN modules. The final patch enables usdhc1 and associated pinctrl settings needed for SDIO WiFi operation on the M.2 connector.
