This breaks out a <linux/pinctrl/consumer.h> header to be used by all pinmux and pinconfig alike, so drivers needing services from pinctrl does not need to include different headers. This is similar to the approach taken by the regulator API. Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
