[PATCH 00/20] drm/i915/display: convert to generic poll_timeout_us()

[Jani Nikula <jani.nikula@intel.com>]

Completely remove the remaining custom i915_utils.h wait macro usage
from display code, and unify on the kernel generic poll_timeout_us()
poll waiter. Also convert existing read_poll_timeout() and
readx_poll_timeout() to poll_timeout_us().

This is a rewrite of [1] switching to the new poll_timeout_us() instead
of read_poll_timeout().

The main functional change is losing the exponentially growing sleep
from the custom macros. This is highlighted in each commit message with
details.


BR,
Jani.
