imx: Return gpio_set_value in gpio_direction_output

2012-04-16T12:53:59+00:00

Return gpio_set_value in gpio_direction_output.
Earlier it returned 0 and ignored gpio_set_value's return value.

sandbox: gpio: add basic driver for simulating GPIOs

2012-03-12T15:03:42+00:00

This provides a way of simulating GPIOs by setting values which are seen
by the normal gpio_get/set_value() calls.

gpio: Replace ARM gpio.h with the common API in include/asm-generic

2012-01-10T02:10:32+00:00

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

extended to the new mxs_gpio.c.

tegra2: Use new GPIO APIs in gpio_config_uart()

2011-12-09T16:30:08+00:00

... rather than open-coding the register accesses.

However, gpio_request() typically stores the "label" parameter in a global
data structure. This causes problems when called from gpio_config_uart(),
since the code is running before relocation. To solve this, pass a NULL
string to gpio_request(), and modify gpio_request() not to touch the string
if it's NULL.
