drivers/leds/leds-gpio.c: use linux/gpio.h rather than asm/gpio.h

2012-03-23T23:58:35+00:00

Direct usage of the asm include has long been deprecated by the
introduction of gpiolib.

drivers/leds/leds-gpio.c: use gpio_get_value_cansleep() when initializing

2011-11-01T00:30:55+00:00

I get the following warning:

My GPIOs are on an I2C port expander, so we must use the *_cansleep()
variant of the GPIO functions.  This is was not being done in
create_gpio_led().

We can change gpio_get_value() to gpio_get_value_cansleep() because it is
only called from the platform_driver probe function, which is a context
where we can sleep.

Only tested on my gpio_cansleep() system, but it seems safe for all
systems.

drivers/leds: Add module.h to files using it implicitly

2011-10-31T23:31:49+00:00

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in the leds
dir are actually calling out for  explicitly in advance.

leds: remove config option LEDS_GPIO_PLATFORM from Kconfig

2011-06-03T18:14:16+00:00

Since the commit a314c5c0040aab51ebb1ecfd37a9198a91962243
(leds/leds-gpio: merge platform_driver with of_platform_driver),
the config option LEDS_GPIO_PLATFORM becomes useless, so remove it.

leds/leds-gpio: merge platform_driver with of_platform_driver

2011-02-28T08:36:39+00:00

Both interfaces can be driven with the same driver, and
of_platform_driver is getting removed.  This patch merges the two
driver registrations.

drivers/leds/leds-gpio.c: properly initialize return value

2010-11-12T15:55:32+00:00

In the event that none of the configs are set (CONFIG_LEDS_GPIO_PLATFORM,
CONFIG_LEDS_GPIO_OF, CONFIG_LEDS_GPIO_PLATFORM), we will return a bogus
value when initializing the module.

of/device: Replace struct of_device with struct platform_device

2010-08-06T15:25:50+00:00

of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.
