Subject: [PATCH 0/3] pinctrl: single: support #pinctrl-cells = 2

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 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.

Drew Fustini (3):
  ARM: dts: change AM33XX_PADCONF macro separate conf and mux
  ARM: dts: am33xx-l4: change #pinctrl-cells from 1 to 2
  pinctrl: single: parse #pinctrl-cells = 2
