GPIO 10 default settings

custom_board

#1

Hi,
in my board the default settings for GPIO 10 is high. meaning when the system is powered up the pin is in HIGH.
i have the option to control it only after system complete it boot up.
How I can change the default settings to Low?

Thx,
Ofer

Did you enable SPI3? GPIO 10 is part of as SPI3 pinctrl (chip select pin, def high) (cf /arch/arm64/boot/dts/qcom/msm8916-pins.dtsi) and selected by blsp_spi3 node in the msm8916 dtsi.

thanks for your prompt treply/
The problem is not to control it, that I can do.
my issue is to change the default during boot.
currently its 1, need to change to 0.

thx,
Ofer
