gpio: palmas: add dt support
Add of_device_id table for Palma GPIO to be enable the driver from DT file. The driver can be registered from DT file as: palmas: tps65913@58 { ::::::::::: palmas_gpio: palmas_gpio { compatible = "ti,palmas-gpio"; gpio-controller; #gpio-cells = <2>; }; }; Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
