Add the pin setup for SPI/I2C configurations that are supported downstream. I can guesstimate the correct settings for other buses, but: - I have no hardware to test it on - Some QUPs are straight up missing pin funcs in TLMM - Vendors probably didn't really care and used whatever was there in the reference design and BSP - should any other be used, they can be configured at a later time Signed-off-by: Konrad Dybcio <konrad.dybcio@linaro.org> --- arch/arm64/boot/dts/qcom/sm6375.dtsi | 43 ++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+)
