Can I simply use dcmi_pins_b (as the first unused identifier) or is there some way to match specific pin groups to an identifier (b, c, d, and so on)? > Current convention is also to place all STM32MP1 pinctrl nodes into > a central file, not in the individual board device trees. Sure, I will update the patch. Thanks for your comments! -- Grzegorz
