Subject: [PATCH v3 02/15] pinctrl: ingenic: use struct pinfunction instead
of struct function_desc
From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
struct function_desc is a wrapper around struct pinfunction with an
additional void *data pointer. This driver doesn't use the data pointer.
We're also working towards reducing the usage of struct function_desc in
pinctrl drivers - they should only be created by pinmux core and
accessed by drivers using pinmux_generic_get_function(). Replace the
struct function_desc objects in this driver with smaller struct
pinfunction instances.
