Subject: [PATCH 74/77] pinctrl: Introduce struct pinfunction and
|
||
|
|
PINCTRL_PINFUNCTION() macro

|
|
||
|
|
There are many pin control drivers define their own data type for
|
||
|
|
pin function representation which is the same or embed the same data
|
||
|
|
as newly introduced one. Provide the data type and convenient macro
|
||
|
|
for all pin control drivers.
