Subject: [PATCH] gpio: palmas: add dt support
Date: Thu, 21 Mar 2013 20:00:14 +0530 [thread overview]
Message-ID: <1363876214-25933-1-git-send-email-ldewangan@nvidia.com> (raw)
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>;
};
};
