These changes enable the flashlight LED driver (fled_rt5033), and add support for switching the light on and off from userspace. In more detail: * CONFIG_FLED_RT5033 enables the flashlight driver * CONFIG_VIDEO_EXYNOS_FIMC_IS is required for the flashlight driver to compile (there seems to be a lot of cross-dependency between the two drivers) * patch 0001 fixes the use of usleep (which no longer exists), to make the kernel compile with those settings With these changes, /sys/class/flashlight/rt-flash-led shows up in sysfs, but it's only possible to control the brightness of the LED, not to switch it on. Patch 0002 is what actually makes the flashlight usable: it makes the /sys/class/flashlight/rt-flash-led/mode file writable. Writing "Torch" there enables the flashlight, writing "Off" disables it again. "Mixed" mode works like "Torch" as well. I have not figured out yet how to trigger the camera flash, so setting the mode to "Flash" is possible, albeit pointless.
