Linus, Sebastian,
As discussed earlier this year[1], this series introduce helpers for group based
pinctrl drivers:
- of_pinctrl_utils_read_function(): reads the function name of a
specified node, and gets the number of groups it should be
applied to.
- of_pinctrl_for_each_function_group(): navigates through the groups of
a specified node, reading at each iteration the name of the current
group.
A generic function to parse nodes for group based drivers is also added, and
then used in the Berlin pinctrl driver:
- pinconf_generic_function_groups_dt_node_to_map()
