Linus Walleij e1c6edcbea 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.
