[PATCH 1/2] arm64: dts: imx8qm-mek: mux and hook up GPIOs related to SD1

[Tamás Szűcs]

Add pinctrl node grouping USDHC1_DATA6, USDHC1_DATA7 and USDHC1_RESET_B and use
them as Write Protect and Card Detect for usdhc2 and regulator enable for
SD1_SPWR respectively.

[PATCH 2/2] arm64: dts: imx8qm-mek: add usdhc pinctrl states to enable higher data rates

[Tamás Szűcs]

Add pinctrl states 'state_100mhz' and 'state_200mhz' to usdhc1 and usdhc2 to
enable higher data rates for eMMC and SD.
