      drm/vc4: kms: Wait for the commit before increasing our clock rate · 244a36e5
      Maxime Ripard authored
      Several DRM/KMS atomic commits can run in parallel if they affect
      different CRTC. These commits share the global HVS state, so we have
      some code to make sure we run commits in sequence. This synchronization
      code is one of the first thing that runs in vc4_atomic_commit_tail().
      
      Another constraints we have is that we need to make sure the HVS clock
      gets a boost during the commit. That code relies on clk_set_min_rate and
      will remove the old minimum and set a new one. We also need another,
      temporary, minimum for the duration of the commit.
      
      The algorithm is thus to set a temporary minimum, drop the previous
      one, do the commit, and finally set the minimum for the current mode.
      
      However, the part that sets the temporary minimum and drops the older
      one runs before the commit synchronization code.
      
      Thus, under the proper conditions, we can end up mixing up the minimums
      and ending up with the wrong one for our current step.
      
      To avoid it, let's move the clock setup in the protected section.

      [danvet: re-apply this from 0c980a00 ("drm/vc4: kms: Wait for the
      commit before increasing our clock rate") because I lost that part in
      my merge resolution in 99b03ca6 ("Merge v5.16-rc5 into drm-next")]

       - Fix qcom mux logic to look at the proper parent table member. Luckily
         this clk type isn't very common.

         out of the bootloader. We will simply skip programming the PLL rate
         if it's already done.
      
       - Use the proper clk_ops for the qcom sm6125 ICE clks.
      
       - Use module_platform_driver() in i.MX as it can be a module.
