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.
