+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.

- 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.
