leds: Make flash and multicolor dependencies unconditional Along the same lines as making devm_led_classdev_register() declared extern unconditional, do the same thing for the two sub-classes that have similar stubs. The users of these interfaces go to great lengths to allow building with both the generic leds API and the extended version, but realistically there is not much use in this, so just simplify it to always rely on it and remove the confusing fallback logic.

The flash module can have 3 or 4 channels and each channel can be controlled indepedently and support full scale current up to 1.5 A. It also supports connecting two channels together to supply one LED component with full scale current up to 2 A. In that case, the current will be split on each channel symmetrically and the channels will be enabled and disabled at the same time.

leds: rt8515: add V4L2_FLASH_LED_CLASS dependency The leds-rt8515 driver can optionall use the v4l2 flash led class, but it causes a link error when that class is in a loadable module and the rt8515 driver itself is built-in: ld.lld: error: undefined symbol: v4l2_flash_init >>> referenced by leds-rt8515.c >>> leds/flash/leds-rt8515.o:(rt8515_probe) in archive drivers/built-in.a Adding 'depends on V4L2_FLASH_LED_CLASS' in Kconfig would avoid that, but it would make it impossible to use the driver without the v4l2 support. Add the same dependency that the other users of this class have instead, which just prevents the broken configuration.

leds: rt8515: Add Richtek RT8515 LED driver This adds a driver for the Richtek RT8515 dual channel torch/flash white LED driver. This LED driver is found in some mobile phones from Samsung such as the GT-S7710 and GT-I8190. A V4L interface is added. We do not have a proper datasheet for the RT8515 but it turns out that RT9387A has a public datasheet and is essentially the same chip. We designed the driver in accordance with this datasheet. The day someone needs to drive a RT9387A this driver can probably easily be augmented to handle that chip too. Sakari Ailus, Pavel Machek and Andy Shevchenko helped significantly in getting this driver right.
