It's supposed to tell the driver which instance # of DSI block it is.
The DSI display bindings on OMAP also had the same issue. It was
dealt with by keeping a copy of the starting MMIO address of each
DSI instance for every supported SoC in the driver, and figure out
which DSI instance the device was through that.
I could do the same here (and drop a similar property for DSI PHY
too). Do you have any suggestions on how the driver could figure
which instance the device is without indirectly figuring out
through some other property?
Thanks for the reviews.
