Currently, pinctrl-single only allows #pinctrl-cells = 1.

This series will allow pinctrl-single to also support #pinctrl-cells = 2

If "pinctrl-single,pins" has 3 arguments (offset, conf, mux) then
pcs_parse_one_pinctrl_entry() does an OR operation on conf and mux to
get the value to store in the register.

To take advantage of #pinctrl-cells = 2, the AM33XX_PADCONF macro in
omap.h is modified to keep pin conf and pin mux values separate.

change log:
- v4: squash patches 2 and 3 together so that git biesct will not result
  in a boot failure

- v3: change order of patches to make sure the pinctrl-single.c patch
  does not break anything without the dts patches

- v2: remove outer parentheses from AM33XX_PADCONF macro as it causes a
  compile error in dtc.  I had added it per suggestion from checkpatch
  about having parentheses around complex values.

Drew Fustini (2):
  pinctrl: single: parse #pinctrl-cells = 2
  ARM: dts: am33xx-l4: change #pinctrl-cells from 1 to 2

Both patches applied to the pinctrl devel branch for v5.9!

Please make sure not to create colliding patches in the DTS files merged
through ARM SoC this merge window.

Yours,
Linus Walleij

Thanks.

Which repo/branch is the best for me to use if I am going to be
posting any further dts patches?
