Commit Message

Dmitry Baryshkov Feb. 9, 2021, 8:28 p.m. UTC
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.
