led: gpio: Sort include headers alphabetically

2014-09-29T17:18:28+00:00

If the inlcude headers aren't sorted alphabetically, then the
logical choice is to append new ones, however that creates a
lot of potential for conflicts or duplicates because every change
will then add new includes in the same location.

drivers/leds: delete non-required instances of include

2014-02-27T17:56:56+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

leds: leds-gpio: add retain-state-suspended property

2014-02-27T17:56:56+00:00

Some gpio-leds need retain the state even in suspend, such as charger led.
But this property missed in devicetree, add it.

leds-gpio: of: led should not be created if its status is disabled

2013-10-25T17:12:55+00:00

now the leds-gpio driver will create every child led node without
checking the status is disabled or not.

for example, if we have a led node like d3, and its status is disabled:
	leds {
		d3 {
			label = "d3";
			gpios = <&pioE 24 0>;
			status = "disabled";
		};
	};

we except the d3 should not be created. And the gpios should not be
request as well.

But current driver will create d3 and request its gpio.

This patch fix this by using for_each_available_child_of_node() and
of_get_available_child_count() to enumerate all child nodes. So the
disabled node will be inavailable.

leds: use dev_get_platdata()

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

leds: leds-gpio: Let device core handle pinctrl

2013-06-20T23:21:33+00:00

Since commit ab78029 (drivers/pinctrl: grab default handles from device core)
we can rely on device core for handling pinctrl, so remove
devm_pinctrl_get_select_default() from the driver.

leds: leds-gpio: remove unnecessary platform_set_drvdata()

2013-06-20T23:21:32+00:00

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.
