We get a link error when V4L2_FLASH_LED_CLASS=m and AS3645A is built-in:

drivers/leds/leds-as3645a.o: In function `as3645a_v4l2_setup':
leds-as3645a.c:(.text+0x258): undefined reference to `v4l2_flash_init'

leds-as3645a.c:(.text+0x784): undefined reference to `v4l2_flash_release'

This adds the same Kconfig dependency that the other V4L2 flash
drivers in drivers/leds use, to avoid that broken configuration.

Add a LED flash class driver for the as3654a flash controller. A V4L2 flash
driver for it already exists (drivers/media/i2c/as3645a.c), and this driver
is based on that.

The PCA955x family of chips are I2C LED blinkers whose pins not used
to control LEDs can be used as general purpose I/Os (GPIOs).

The following adds such a support by defining different operation
modes for the pins (See bindings documentation for more details). The
pca955x driver is then extended with a gpio_chip when some of pins are
operating as GPIOs. The default operating mode is to behave as a LED.

The GPIO support is conditioned by CONFIG_LEDS_PCA955X_GPIO.

SEAD3 is using the generic syscon & regmap based register-bit-led
driver as of commit c764583f40b8 ("MIPS: SEAD3: Use register-bit-led
driver via DT for LEDs") merged in the v4.9 cycle. As such the custom
SEAD-3 LED driver is now unused, so remove it.

All users of the Versatile LED driver are deleted and replaced
with the very generic leds-syscon. Delete the old driver.

Motorola CPCAP is a PMIC (power management integrated circuit) found
in multiple smartphones. This driver adds support for the chip's LED
controllers. This introduces support for all controllers used by the
Droid 4. According to Motorola's driver (no datasheets available)
there a couple of more LED controllers. I did not add support for
them, since I cannot verify that they work with my modifications.

In ACPI world any ID should be carefully chosen and registered
officially. The discussion [1] as I read it gets to wilful assignment
an ID for non-existing real DSDT example.

Rafael already told [2] how this device would be enumerated using
compatible string. To be more precise look at the possible DSDT excerpt
below:

	Device (LDX0) {
		Name (_HID, "PRP0001")
		Name (_DDN, "TI LP3952 compatible led driver")
		...
	})

	Name (_DSD, Package () {
		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
		Package () {
			Package () {"compatible", "ti,lp3952"},
			...
		}
	})

Based on above, remove non-official ACPI IDs and enumeration from the
driver.

Note: currently driver has no compatible strings at all, to make above
working one should add at least one.

MT6323 PMIC is a multi-function device that includes LED function.
It allows attaching up to 4 LEDs which can either be on, off or dimmed
and/or blinked with the controller.

The dell-led driver handles a specific WMI GUID present on some Dell
laptops and as such it belongs in the x86 platform driver subsystem.
Source code is moved along with the relevant Kconfig and Makefile
entries, with some minor modifications:

  - Kconfig option is renamed from CONFIG_LEDS_DELL_NETBOOKS to
    CONFIG_DELL_WMI_LED,

  - the X86 Kconfig dependency is removed as the whole
    drivers/platform/x86 menu depends on it, so there is no need to
    duplicate it,

  - the name of the module's source file is removed from the header
    comment to avoid the need to update it in the future.
