Subject: [PATCH v2 0/4] LED: Add basic LP5860 LED matrix driver

The lp5860 is a LED matrix driver with 18 constant current sinks and 11
scan switches which allows controlling up to 198 LED dots.

This series adds just the basic support for the device on the SPI bus.
It is also possible to use it on I2C. The interface can be
switched/selected via an interface select pin.
