Instead of applying few independent series, I need to: 1. Apply, drop patches (or apply 1-by-1). 2. Re-order patches. 3. Apply remaining 1-by-1 on pinctrl. Please organize your series per subsystem. SoC is a subsystem. pinctrl is different. Bindings always go first, I asked for it already. And here everything is mixed. Best regards, Krzysztof
