Subject: Re: [PATCH v4 3/3] arm64: dts: qcom: sc7180: align TLMM pin
 configuration with DT schema

Quoting Krzysztof Kozlowski (2022-10-20 15:51:35)
> DT schema expects TLMM pin configuration nodes to be named with
> '-state' suffix and their optional children with '-pins' suffix.
>
> Merge subnodes named 'pinconf' and 'pinmux' into one entry, add function
> where missing (required by bindings for GPIOs) and reorganize overriding
> pins by boards.
>
> Split the SPI and UART configuration into separate nodes
> 1. SPI (MOSI, MISO, SCLK), SPI chip-select, SPI chip-select via GPIO,
> 2. UART per each pin: TX, RX and optional CTS/RTS.
>
> This allows each board to customize them easily without adding any new
> nodes.
