Subject: [PATCH 05/10] arm64: dts: qcom: sm6375: Add pin configs for some QUP configurations
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
