leds: fix the incorrect display in menuconfig

2011-06-16T03:04:01+00:00

Seems when a config option does not have a dependency of the menuconfig,
it messes the display of the rest configs, even if it's a hidden one.

leds: move LEDS_GPIO_REGISTER out of menuconfig NEW_LEDS

2011-06-16T03:04:00+00:00

Commit 4440673a95e6 ("leds: provide helper to register "leds-gpio"
devices") broke the display of the NEW_LEDS menu as it didn't depend on
NEW_LEDS and so made "LED drivers" and "LED Triggers" appear at the same
level as "LED Support" instead of below it as it was before 4440673a.

Moving LEDS_GPIO_REGISTER out of the menuconfig NEW_LEDS fixes this
unintended side effect.

drivers/leds/leds-asic3: make LEDS_ASIC3 depend on LEDS_CLASS

2011-06-16T03:04:00+00:00

We call led_classdev_unregister/led_classdev_register in
asic3_led_remove/asic3_led_probe, thus make LEDS_ASIC3 depend on
LEDS_CLASS.

This patch fixes below build error if LEDS_CLASS is not configured.

leds: Add ASIC3 LED support

2011-05-26T17:45:46+00:00

Add LED support for the HTC ASIC3. Underlying support is provided by the mfd/asic3 and leds/leds-asic3 drivers. An example configuration is provided by the pxa/hx4700 platform.

leds: provide helper to register "leds-gpio" devices

2011-05-25T15:39:51+00:00

This function makes a deep copy of the platform data to allow it to live
in init memory.  For a kernel that supports several machines and so
includes the definition for several leds-gpio devices this saves quite
some memory because all but one definition can be free'd after boot.

As the function is used by arch code it must be builtin and so cannot go
into leds-gpio.c.

leds: remove the leds-h1940 driver

The H1940 machine now uses leds-gpio and leds-h1940 has no users anymore.

drivers/leds/leds-pca9532.c: add gpio capability

2011-05-25T15:39:50+00:00

Allow unused leds on pca9532 to be used as gpio.  The board I am working
on now has no less than 6 pca9532 chips.  One chips is used for only leds,
one has 14 leds and 2 gpio and the rest of the chips are gpio only.

There is also one board in mainline which could use this capabilty;
arch/arm/mach-iop32x/n2100.c
 232         {       .type = PCA9532_TYPE_NONE }, /* power OFF gpio */
 233         {       .type = PCA9532_TYPE_NONE }, /* reset gpio */

This patch defines a new pin type, PCA9532_TYPE_GPIO, and registers a
gpiochip if any pin has this type set.  The gpio will registers all chip
pins but will filter on gpio_request.

leds: fix up dependencies

2010-12-02T22:51:15+00:00

It's not useful to build LED triggers when there's no LEDs that can be
triggered by them.  Therefore, fix up the dependencies so that this
cannot happen, and fix a few users that select triggers to depend on
LEDS_CLASS as well (there is also one user that also selects LEDS_CLASS,
which is OK).
