[PATCH v1 00/11] pinctrl: pinmux: Embed and reuse struct pinfunction

[PATCH v1 00/11] pinctrl: pinmux: Embed and reuse struct pinfunction

[Andy Shevchenko]

As promised to Linus W. there is a series that converts struct function_desc
to use struct pinfunction. With this it both struct group_desc and struct
function_desc will rely on the generic data types (struct pingroup and struct
pinfunction respectively).

I haven't compiled everything, some builds might fail. Anyway, comments, reviews,
testing are all appreciated.

Andy Shevchenko (11):
  pinctrl: berlin: Make use of struct pinfunction
  pinctrl: equilibrium: Make use of struct pinfunction
  pinctrl: ingenic: Provide a helper macro INGENIC_PIN_FUNCTION()
  pinctrl: mediatek: Provide a helper macro PINCTRL_PIN_FUNCTION()
  pinctrl: pinmux: Add a convenient define PINCTRL_FUNCTION_DESC()
  pinctrl: pinmux: Embed struct pinfunction into struct function_desc
  pinctrl: imx: Convert to use func member
  pinctrl: ingenic: Convert to use func member
  pinctrl: keembay: Convert to use func member
  pinctrl: mediatek: Convert to use func member
  pinctrl: pinmux: Remove unused members from struct function_desc

This helps further refactoring.

[Andy Shevchenko]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

struct function_desc is a particular version of the struct pinfunction
with associated opaque data. Start switching pin control core and
drivers to use it explicitly.
