Cover letter [PATCH 0/3] backlight/arcxcnn fix vendor prefix in driver and bindings and add support for arc1, arc3
The vendor-prefix.txt file correctly uses the prefix arctic for ArcticSand. The ArcticSand driver and the device tree bindings for it incorreclty use just arc. This mismatch was an error in the original patchset for the driver and is fixed in the first two patches here.
ArcticSand has been purchased by Peregrine Semiconductor, now pSemi. The company wishes to continue using the ArcticSand name and arctic prefix for its LED backlight drivers.
There are two newer chips created by ArcticSand team. The chips are very similar to the arc2 chip supported by the current kernel driver. Support for the two new chips (arc1 family and arc3 family) is added here based on reading the chip id via i2c in probe and making minor adjustments to ranges and register addresses based on the id.
