Thanks, that makes it simple: the interrupt controller, I2C and GPIO nodes stay as they are, and the pin controller, when it comes, gets one node for the five mux registers. I checked the boot loader's pin mux on the board: it leaves the reset button line and the touchscreen interrupt line muxed to GPIO, so the dts does not change with the mux register gone from the GPIO binding. > My take would probably be not sending new versions until at least 48h > has passed since the last reply on the current version, rather than 48h > or w/e from time of posting. Noted. Arnd also asked to wait for the 7.4 merge window to close, so the next version comes on top of v7.4-rc1. Thanks, Fil
