#1514683 — [PATCHv2 0/4] Generic #pinctrl-cells and and pinctrl_parse_index_with_args

From	Tony Lindgren <tony@atomide.com>
Date	2016-11-03 17:40 +0100
Subject	[PATCHv2 0/4] Generic #pinctrl-cells and and pinctrl_parse_index_with_args
Message-ID	<sztdv-6nD-5@gated-at.bofh.it>

Hi all,

Here a repost of some pinctrl changes to introduce #pinctrl-cells and
a generic parser pinctrl_parse_index_with_args that the drivers can
optionally use.

Regards,

Tony

Changes from v1:

- Update based on comments from Linus Walleij to not pass
  #pinctrl-cells as an argument and improve the binding
  documentation

Tony Lindgren (4):
  pinctrl: Introduce generic #pinctrl-cells and
    pinctrl_parse_index_with_args
  pinctrl: single: Use generic parser and #pinctrl-cells for
    pinctrl-single,pins
  pinctrl: single: Use generic parser and #pinctrl-cells for
    pinctrl-single,bits
  ARM: dts: Add #pinctrl-cells for pinctrl-single instances

#1514684 — [PATCH 4/4] ARM: dts: Add #pinctrl-cells for pinctrl-single instances

From	Tony Lindgren <tony@atomide.com>
Date	2016-11-03 17:40 +0100
Subject	[PATCH 4/4] ARM: dts: Add #pinctrl-cells for pinctrl-single instances
Message-ID	<sztdv-6nD-11@gated-at.bofh.it>
In reply to	#1514683

Drivers using pinctrl-single,pins have #pinctrl-cells = <1>, while
pinctrl-single,bits need #pinctrl-cells = <2>.

Note that this patch can be optionally applied separately from the
driver changes as the driver supports also the legacy binding without
#pinctrl-cells.

We can now use generic parser and keep things compatible with the
old binding.

+Optionally an altenative binding can be used if more suitable depending on the

+pin controller instances, naming each pin and function can easily become
+unmaintainable. This is especially the case if the same controller is used for
+different pins and functions depending on the SoC revision and packaging.
+
+For cases like this, the pin controller driver may use pinctrl-pin-array helper
+binding with a hardware based index and a number of pin configuration values:

+Above #pinctrl-cells specifies the number of value cells in addition to the
+index of the registers. This is similar to the interrupts-extended binding with
+one exception. There is no need to specify the phandle for each entry as that

+node. Further having the phandle pointing to another pin controller would not
+currently work as the pinctrl framework uses named modes to group pins for each
+pin control device.

+The index for pinctrl-pin-array must relate to the hardware for the pinctrl
+registers, and must not be a virtual index of pin instances. The reason for
+this is to avoid mapping of the index in the dts files and the pin controller
+driver as it can change.

Nah. I just did this:
