pinctrl: tegra: define GPIO compatible node per SoC
Tegra 2 uses a different GPIO controller which uses "tegra20-gpio" as compatible string. Make the compatible string the GPIO node is using a SoC specific property. This prevents the kernel from registering the GPIO range twice in case the GPIO range is specified in the device tree. Fixes: 9462510ce31e ("pinctrl: tegra: Only set the gpio range if needed") Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
