[PATCH 00/18] drm/i915/display: convert to generic read_poll_timeout()

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

Convert waits that are not related to MMIO reads to the generic iopoll.h
read_poll_timeout() helper.

Together with [1] and [2], this series completely removes the custom
i915_utils.h wait macro usage from display code, and unifies on the
kernel generic poll waiter.


BR,
Jani.
