Add PCIe pinctrl entries in stm32mp25-pinctrl.dtsi init: forces GPIO to low while probing so CLKREQ is low for phy_init default: restore the AFMUX after controller probe Add Analog pins of PCIe to perform power cycle Signed-off-by: Christian Bruel <christian.bruel@foss.st.com> --- arch/arm64/boot/dts/st/stm32mp25-pinctrl.dtsi | 20 +++++++++++++++++++ 1 file changed, 20 insertions(+)
