It would be a minor conflict, though, and you would have to resolve that yourself, when merging my renesas-pinctrl PR. So when you will send a PR to The Other Linus, there won't be a conflict anymore, and no angriness ;-) Thanks! Gr{oetje,eeting}s, Geert

Can you just drop drivers/pinctrl/renesas/pinctrl.c from this patch? Rob

You just exposed how lazy I am ;) OK I did that, patch applied sans the renesas hunk. Yours, Linus Walleij

It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.
