Subject: [PATCH v2 0/3] pinctrl: single: support #pinctrl-cells = 2
Date: Fri, 19 Jun 2020 11:06:05 +0200	[thread overview]
Message-ID: <20200619090608.94948-1-drew@beagleboard.org> (raw)

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.

v2 changes:
- 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.
