2012-01-09gpio: Replace ARM gpio.h with the common API in include/asm-genericJoe Hershberger
ARM boards should use the generic GPIO API This means changing gpio to unsigned type Remove the unused gpio_toggle() function which is not part of the API Comment that free should not modify pin state Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Cc: Joe Hershberger <joe.hershberger@gmail.com> fixed merge conflict in da8xx_gpio.c, tegra2_gpio.c, and extended to the new mxs_gpio.c.

2011-10-27omap: Don't use gpio_free to change direction to inputJoe Hershberger
gpio_free() should not have the side effect of setting the line to input since this prevents the gpio command from being able to set a line as output.

2011-09-13omap: gpio: Use generic APISanjeev Premi
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.
