6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Lukasz Czechowski <lukasz.czechowski@xxxxxxxxxxxxx> commit 4eee627ea59304cdd66c5d4194ef13486a6c44fc upstream. In the PX30-uQ7 (Ringneck) SoM, the hardware CTS and RTS pins for uart5 cannot be used for the UART CTS/RTS, because they are already allocated for different purposes. CTS pin is routed to SUS_S3# signal, while RTS pin is used internally and is not available on Q7 connector. Move definition of the pinctrl-0 property from px30-ringneck-haikou.dts to px30-ringneck.dtsi. This commit is a dependency to next commit in the patch series, that disables DMA for uart5.
