[PATCH v3 3/4] arm64: dts: qcom: sm8250: add pinctrl for SPI using GPIO as a CS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



GENI SPI controller shows several issues if it manages the CS on its own
(see 37dd4b777942 ("arm64: dts: qcom: sc7180: Provide pinconf for SPI to
use GPIO for CS")) for the details. Provide pinctrl entries for SPI
controllers using the same CS pin but in GPIO mode.
