3.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Balaji T K <balajitk@xxxxxx> commit 2ba2866f782f7f1c38abc3dd56d3295efd289264 upstream. pin mux wl12xx_gpio and wl12xx_pins should be part of omap4_pmx_core and not omap4_pmx_wkup. So, move wl12xx_* to omap4_pmx_core. Fix the following error message: pinctrl-single 4a31e040.pinmux: mux offset out of range: 0x38 (0x38) pinctrl-single 4a31e040.pinmux: could not add functions for pinmux_wl12xx_pins 56x SDIO card is not detected after moving pin mux to omap4_pmx_core since sdmmc5_clk pull is disabled. Enable Pull up on sdmmc5_clk to detect SDIO card. This fixes a regression where WLAN did not work after a warm reset or after one up/down cycle that happened when we move omap4 to boot using device tree only.
