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.

mfd: Use mfd cell platform_data for 88pm860x cells platform bits

2011-05-26T17:45:12+00:00

With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

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.

drivers/leds/leds-lm3530.c: add regulator

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

Add add regulator support to lm3530 driver.  The lm3530 driver needs to
get proper regulator during device probe and enable it before accessing
the device.  Also it disables the regulator in case of brightness ==
LED_OFF, and puts it back during driver removal.

leds: remove the leds-h1940 driver

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

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

drivers/leds/leds-pca9532.c: add support pca9530, pca9531 and pca9533

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

The pca953x family are only different in number of leds and register
layout Adding chipinfo to use driver with whole pca953x family Rename
driver to pca953x, but left files and platformflags named pca9532.

Tested with pca9530 and pca9533

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: support automatic start of blinking with ledtrig-timer

2011-05-25T15:39:49+00:00

By setting initial values blink_delay_on and blink_delay_off in a
led_classdev struct, this change starts the blinking when the led is
initialized.

With this patch, you can initialize blink_delay_on and blink_delay_off in
led_classdev with default_trigger set to "timer", and the led will start
up blinking.  The current ledtrig-timer implementation ignores any initial
blink_delay_on/blink_delay_off settings, and requires setting
blink_delay_on/blink_delay_off (typically from userspace) before the led
blinks.
