This patch defines DSI_HTX_TO, DSI_LRX_H_TO, DSI_PWAIT_TO
and DSI_TA_TO registers for DSI transcoders '0' and '1'.
They are used for contention recovery on DPHY.
v2: Define SHIFT for bitfields.
v3 by Jani:
- Fix timeout bit definitions
Ok. I was little confused with BSPEC description "HW will set this bit,
SW must clear it with a write of 1b"
meaning timeout will happen (reverse behavior) when bit is '0' :).
Regards,
Madhav
