for dsixpllbyte to ensure that the parent (VCO) is set at this
rate.
An additional divider (POSTDIV1) generates the bitclk. Since bit clock
can be derived from byteclock, we calculate it internally, and don't
expose it as a clock.

DSI PHY on MSM8960 and APQ8064 is a 28nm PHY that's different from the
supported 28nm LP PHY found in newer chips.
Add support for the new PHY.

The DSI PLL and PHY registers are already there for 8960, but their
offsets are relative to the top level DSI controller base.
Make the offsets relative to the individual sub blocks. Add "28nm" in
the register names while we're at it.

Add support for DSI on 8960/8064. The DSI IP used in these chips is an
older version(DSIv2) of what we have right now(DSI6G).
The bulk of the additions come thanks to a different PHY/PLL. The DSI
host in itself doesn't have too many changes.

This list will be used to find the mipi_dsi_host corresponding to the

the possibility of the host removing the dsi device without the
peripheral driver being aware of it. I don't know a good way to solve
this. Some suggestions here would be of help too.

in a situation where a driver tries to create a device with a virtual
channel already taken by a device populated in DT.

The new device creation process tries to closely follow what's been done
in i2c_new_device in i2c-core.

Some comments on these would help.
