> Subject: [Intel-gfx] [PATCH 05/29] drm/i915/tc: Move TC port fields to a new
> intel_tc_port struct
>
> Move the TC port specific fields from intel_digital_port to a new
> intel_tc_port
> struct. Pass an intel_tc_port pointer to all static functions in intel_tc.c
> keeping
> dig_port accessible for these via a pointer stored in the new struct.
>
> The next patch will allocate the intel_tc_port dynamically, allowing moving
> the
> struct definition to intel_tc.c.
