Subject: [PATCH 0/3] leds: Add Broadchip BCT3024 LED driver

Hi,

I'm sending a series of patches to add support for the Broadchip BCT3024
LED driver. The first adds Broadchip to the DT vendor prefixes, the
second is the DT bindings documentation and the third is the driver
itself.

The Broadchip BCT3024 is an I2C LED driver with 24 independent channels,
each with 256 brightness levels. It is targeted mainly for mobile phones
and other hand-held devices.

As we use the chip in a device that needs to keep its power consumption
to a minimum, I added support for the runtime PM to let the kernel
disable the chip and its power supply when brightness is set to zero.

Any comments are welcome.
