The DSI0 and DSI1 blocks on the 2835 are related hardware blocks.
Some registers move around, and the featureset is slightly different,
as DSI1 (the 4-lane DSI) is a later version of the hardware block.
This driver doesn't yet enable DSI0, since we don't have any hardware
to test against, but it does put a lot of the register definitions and
code in place.
v2: Use the clk_hw interfaces, don't set CLK_IS_BASIC (from review by
Stephen Boyd)

Choose this option if you have a system that has a Broadcom
|
|
VC4 GPU, such as the Raspberry Pi or other BCM2708/BCM2835.

This driver requires that "avoid_warnings=2" be present in
|
|
the config.txt for the firmware, to keep it from smashing
|

our display setup.
