      drm/i915: Apply post-sync write for pipe control invalidates · 7d54a904
      Chris Wilson authored
      When invalidating the TLBs it is documentated as requiring a post-sync
      write. Failure to do so seems to result in a GPU hang.
      
      Exposure to this hang on IVB seems to be a result of removing the extra
      stalls required for SNB pipecontrol workarounds:

          drm/i915: Only apply the SNB pipe control w/a to gen6
      
      Note: Manually switch the pipe_control cmd to 4 dwords to avoid a
      (silent) functional conflict with -next. This way will get a loud (but
      conflict with next (since the scratch_addr has been deleted there).

      drm/i915: reorder edp disabling to fix ivb MacBook Air · 35a38556
      Daniel Vetter authored
      eDP is tons of fun. It turns out that at least the new MacBook Air 5,1
      model absolutely doesn't like the new force vdd dance we've introduced
      in
      
      commit 6cb49835
      Author: Daniel Vetter <daniel.vetter@ffwll.ch>

          drm/i915: enable vdd when switching off the eDP panel
      
      But that patch also tried to fix some neat edp sequence issue with the
      force_vdd timings. Closer inspection reveals that we've raised
      force_vdd only to do the aux channel communication dp_sink_dpms. If we
      move the edp_panel_off below that, we don't need any force_vdd for the
      disable sequence, which makes the Air happy.
      
      Unfortunately the reporter of the original bug that the above commit
      fixed is travelling, so we can't test whether this regresses things.
      But my theory is that since we don't check for any power-off ->
      force_vdd-on delays in edp_panel_vdd_on, this was the actual
      root-cause of this failure. With that force_vdd dance completely
      eliminated, I'm hopeful the original bug stays fixed, too.
      
      For reference the old bug, which hopefully doesn't get broken by this:
      
      https://bugzilla.kernel.org/show_bug.cgi?id=43163
      
      In any case, regression fixers win over plain bugfixes, so this needs
      to go in asap.
      
      v2: The crucial pieces seems to be to clear the force_vdd flag
      uncoditionally, too, in edp_panel_off. Looks like this is left behind
      by the firmware somehow.
      
      v3: The Apple firmware seems to switch off the panel on it's own, hence
      we still need to keep force_vdd on, but properly clear it when switching
      the panel off.

      GPIO: gpio-pxa: fix building without CONFIG_OF · f43e04ec
      Arnd Bergmann authored
      Commit 72121572 ("GPIO: gpio-pxa: fix devicetree functions") added an
      "xlate" function pointer to the irq_domain_ops, but this function is nor
      declared or defined anywhere when CONFIG_OF is disabled, causing the
      build error:
      
        drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function)
      
      Extending the DT-only code section to cover the irq_domain_ops and the
      pxa_gpio_dt_ids solves this problem and makes it clearer which code is
      actually used without DT.
