      drm/komeda: Make Komeda interrupts shareable · 2cfb1981
      Ayan Halder authored
      Komeda interrupts may be shared with other hardware blocks.
      One needs to use devm_request_irq() with IRQF_SHARED to create a shared
       interrupt handler.
      As a result of not using drm_irq_install() api, one needs to set
      "(struct drm_device *)->irq_enabled = true/false" to enable/disable
      vblank interrupts.
      
      Changes from v1:-
      1. Squashed the following two patches into one (as the second patch is a
      consequence of the first one):-
         drm/komeda: Avoid using DRIVER_IRQ_SHARED
         drm/komeda: Enable/Disable vblank interrupts
      2. Fixed the commit message (as pointed by Daniel Vetter)
      3. Removed calls to 'drm_irq_uninstall()' as we are no longer using
      drm_irq_install()
      4. Removed the struct member 'komeda_kms_driver.irq_handler' as it is not
      used anywhere.

      drm/komeda: fix 32-bit komeda_crtc_update_clock_ratio · 0b044a99
      Arnd Bergmann authored
      clang points out a bug in the clock calculation on 32-bit, that leads
      to the clock_ratio always being zero:
      
      drivers/gpu/drm/arm/display/komeda/komeda_crtc.c:31:36: error: shift count >= width of type [-Werror,-Wshift-count-overflow]
              aclk = komeda_calc_aclk(kcrtc_st) << 32;
      
      Move the shift into the division to make it apply on a 64-bit
      variable. Also use the more expensive div64_u64() instead of div_u64()
      to account for pxlclk being a 64-bit integer.
      
      Fixes: 1f7f9ab7 ("drm/komeda: Add engine clock requirement check for the downscaling")
