Subject: [PATCH 09/42] drm/i915/tc: move legacy code out of the
main _max_lane_count() func
From: Luca Coelho <luciano.coelho@xxxxxxxxx>
This makes the code a bit more symmetric and readable, especially when we
start adding more display version-specific alternatives.

Rather than having two functions:
mtl_tc_port_get_max_lane_count()
& intel_tc_port_get_max_lane_count() that both call:
with_intel_display_power(i915, POWER_DOMAIN_DISPLAY_CORE, wakeref)
lane_mask = intel_tc_port_get_lane_mask(dig_port);
to get the lane mask the us directly pass the lane_mask to the above two functions
and make the call for getting the lane_mask common i.e lets call it in
intel_tc_port_fia_max_lane_count().
Maybe, but I will let this to be decided between you and Luca. Pasting
from the cover letter:
3. Patches 7 through 10 can also be ignored: they are not
applied yet, but being reviewed in other patch series by its
author[2].
[2] https://patchwork.freedesktop.org/series/120980/
The only reason I added them here is that since this series will take
some time to be applied, I figured it would be better not to create
unnecessary conflicts. I expect these patches to merge soon so I will
just drop them in the next revision of this series.
thanks
