pinctrl: add pin list based GPIO ranges
Traditionally, GPIO ranges are based on consecutive ranges of both GPIO and pin numbers. This patch allows for GPIO ranges with arbitrary lists of pin numbers. Signed-off-by: Christian Ruppert <christian.ruppert@abilis.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
