[v3,0/4] arm64: dts: qcom: qrb5165-rb5: use GPIO as SPI0 CS

Message

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). Configure SPI0 CS pin as a GPIO.

Changes since v2:
 - Move pinctrl-names to the board file.
 - Reorder CS/CS-gpio/data-clk nodes to follow alphabetical sort.

Changes since v1:
 - Split sm8250's spi pin config into mux/config parts, split away CS
   handling from main SPI pinctrl nodes.

Dmitry Baryshkov (4):
      arm64: dts: qcom: sm8250: split spi pinctrl config
      arm64: dts: qcom: sm8250: further split of spi pinctrl config
      arm64: dts: qcom: sm8250: add pinctrl for SPI using GPIO as a CS
      arm64: dts: qcom: qrb5165-rb5: switch into using GPIO for SPI0 CS
