[PATCH V4 0/7] pinctrl: imx: add imx7ulp pinctrl support

[Dong Aisheng]

i.MX 7ULP has three IOMUXC instances: IOMUXC0 for M4 ports,
IOMUXC1 for A7 ports and IOMUXC DDR for DDR interface.

This patch series adds the IOMUXC1 support for A7.
It only supports generic pin config.

ChangeLog:
v3->v4:
 This patch series is a combine of the following patches per
 Maintainer's request.
[PATCH V3 1/2] dt-bindings: pinctrl: add imx7ulp pinctrl binding doc
https://www.spinics.net/lists/arm-kernel/msg582995.html
[PATCH V3 2/2] pinctrl: imx: add imx7ulp driver
https://www.spinics.net/lists/arm-kernel/msg582996.html
[PATCH 0/2] pinctrl: pinctrl-imx: add gpio support for mx7ulp
https://www.spinics.net/lists/arm-kernel/msg580993.html

 Detailed changes as follows:
 * change pad name to IMX7ULP_PAD_X style
 * switch to generic pinmux property
 * remove input/output generic property decodes as the standard
   input/out property name are still under discussing.
   It does not affect the normal GPIO function as imx7ulp pinctrl
   driver supports gpio_set_direction which will set input/output enable
   automatically.
   See: [PATCH V4 7/7] pinctrl: pinctrl-imx7ulp: add gpio_set_direction
   It will be added back later for other pads once the standard property
   is determined.

Dong Aisheng (7):
  dt-bindings: pinctrl: extend the pinmux property to support integers
    array
  dt-bindings: pinctrl: add imx7ulp pinctrl binding doc
  pinctrl: imx: switch to use the generic pinmux property
  pinctrl: imx: add imx7ulp driver
  pinctrl: imx: remove gpio_request_enable and gpio_disable_free
  pinctrl: imx: make imx_pmx_ops.gpio_set_direction platform specific
    callbacks
  pinctrl: pinctrl-imx7ulp: add gpio_set_direction support
