What ensures that the LPI pins are being muxed out on the pads of the SoC? There's the eGPIO support in the tlmm driver, which seems to let us override the LPI pins and mux them away from this pinctrl device to the tlmm pinctrl device. Should this driver be requesting gpios from tlmm and making sure they're not muxed away to tlmm so we don't have conflicts?
