ARM: dts: imx53-qsb: Let the codec control MCLK pinctrl (3d177f48) · Commits · 戴 / test

The hog pinctrl hog is meant for pins that do not have an associated driver. The MX53_PAD_GPIO_0__CCM_SSI_EXT1_CLK pin is the one that provides the MCLK signal to the SGTL5000 codec, so a better represenation is to move it under the codec node. While at it, change the pinctrl value from 0x80000000 to the POR reset value of register IOMUXC_SW_PAD_CTL_PAD_GPIO_0. Signed-off-by:
