* gpio: add gpio_is_valid() to omap_gpio APINikita Kiryanov2012-12-101-0/+7

* omap: gpio: Use generic APISanjeev Premi2011-09-131-15/+0
| | | | | | | | | | | | | | | Convert all OMAP specific functions to use the common API definitions in include/asm/gpio.h. In the process, made few additional changes: - Use -EINVAL consistently. -1 was used in many places. - Removed one-liner static functions that were used only once. Replaced the content as necessary. - Combines implementation of functions omap_get_gpio_dataout() and omap_get_gpio_datain(). To do so, new static function _get_gpio_direction() was added.
