Add the "1v8" pinctrl state and sd-uhs-sdr50 property to SDHI{0,2}.Signed-off-by: Ben Hutchings <[email protected]> --- None of the states includes the CD pins, as they can't be allocated both through pinctrl and as GPIOs. But the Lager manual shows these signals being pulled up to the same variable voltage as the other signals. This might possibly lead to spurious card detect interrupts after switching to 1.8V signalling.
