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() [1] https://lkml.org/lkml/2014/5/17/38 Antoine Tenart (4): Documentation: bindings: pinctrl: document the generic groups property pinctrl: add helpers for group based drivers pinctrl: add a generic way to map node to map for group based drivers pinctrl: berlin: use the generic node to map function .../bindings/pinctrl/pinctrl-bindings.txt | 1 + drivers/pinctrl/berlin/Kconfig | 1 + drivers/pinctrl/berlin/berlin.c | 53 +--------------------- drivers/pinctrl/pinconf-generic.c | 36 +++++++++++++++ drivers/pinctrl/pinctrl-utils.c | 26 +++++++++++ drivers/pinctrl/pinctrl-utils.h | 9 ++++ include/linux/pinctrl/pinconf-generic.h | 3 ++ 7 files changed, 78 insertions(+), 51 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
