Subject: [PATCH 2/3] ACPI / watchdog: Prefer iTCO_wdt on Lenovo Z50-70
WDAT table on Lenovo Z50-70 is using RTC SRAM (ports 0x70 and 0x71) to
store state of the timer. This conflicts with Linux RTC driver
(rtc-cmos.c) who fails to reserve those ports for itself preventing RTC
from functioning. In addition the WDAT table seems not to be fully
functional because it does not reset the system when the watchdog times
out.
On this system iTCO_wdt works just fine so we simply prefer to use it
instead of WDAT. This makes RTC working again and also results working
watchdog via iTCO_wdt.

Subject: [PATCH 2/3] drm/i915/edp: Only use the alternate fixed mode if it's
asked for
In commit dc911f5bd8aa ("drm/i915/edp: Allow alternate fixed mode for
eDP if available."), the patch allows for the use of an alternate fixed
mode if it is available, but the patch was not ensuring that the only
time the alternate mode is used is when it is specifically requested.
This patch adds an additional comparison to intel_edp_compare_alt_mode
to ensure that we only use the alternate mode if it is directly
requested.
Fixes: dc911f5bd8aac ("Allow alternate fixed mode for eDP if available.")

Subject: [PATCH 3/3] Revert "drm/i915/edp: Allow alternate fixed mode for eDP
if available."
This reverts commit dc911f5bd8aacfcf8aabd5c26c88e04c837a938e.
Per the report, no matter what display mode you select with xrandr, the
i915 driver will always select the alternate fixed mode. For the
reporter this means that the display will always run at 40Hz which is
quite annoying. This may be due to the mode comparison.
But there are some other potential issues. The choice of alt_fixed_mode
seems dubious. It's the first non-preferred mode, but there are no
guarantees that the only difference would be refresh rate. Similarly,
there may be more than one preferred mode in the probed modes list, and
the commit changes the preferred mode selection to choose the last one
on the list instead of the first.
(Note that the probed modes list is the raw, unfiltered, unsorted list
of modes from drm_add_edid_modes(), not the pretty result after a
drm_helper_probe_single_connector_modes() call.)
Finally, we already have eerily similar code in place to find the
downclock mode for DRRS that seems like could be reused here.
Back to the drawing board.
Note: This is a hand-crafted revert due to conflicts. If it fails to
backport, please just try reverting the original commit directly.

The specification update indicates these have the same errate for
implementing non-standard ACS capabilities.
