+
+commit 8b2be55f4d6c1099d7f629b0ed7535a5be788c83 upstream.
+
+For SOC21 ASICs, there is an issue in re-enabling PM features if a
+suspend got aborted. In such cases, reset the device during resume
+phase. This is a workaround till a proper solution is finalized.

+Subject: drm/i915/cdclk: Fix CDCLK programming order when pipes are active
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Ville Syrjälä <ville.syrjala@linux.intel.com>
+
+commit 7b1f6b5aaec0f849e19c3e99d4eea75876853cdd upstream.
+
+Currently we always reprogram CDCLK from the
+intel_set_cdclk_pre_plane_update() when using squash/crawl.
+The code only works correctly for the cd2x update or full
+modeset cases, and it was simply never updated to deal with
+squash/crawl.
+
+If the CDCLK frequency is increasing we must reprogram it
+before we do anything else that might depend on the new
+higher frequency, and conversely we must not decrease
+the frequency until everything that might still depend
+on the old higher frequency has been dealt with.
+
+Since cdclk_state->pipe is only relevant when doing a cd2x
+update we can't use it to determine the correct sequence
+during squash/crawl. To that end introduce cdclk_state->disable_pipes
+which simply indicates that we must perform the update
+while the pipes are disable (ie. during
+intel_set_cdclk_pre_plane_update()). Otherwise we use the
+same old vs. new CDCLK frequency comparsiong as for cd2x
+updates.
+
+The only remaining problem case is when the voltage_level
+needs to increase due to a DDI port, but the CDCLK frequency
+is decreasing (and not all pipes are being disabled). The
+current approach will not bump the voltage level up until
+after the port has already been enabled, which is too late.
+But we'll take care of that case separately.
+
+v2: Don't break the "must disable pipes case"
+v3: Keep the on stack 'pipe' for future use
