      drm/omap: improve DPI clock selection on DRA7xx · 7bbdef2b
      Tomi Valkeinen authored
      The clock source selection for the LCD outputs is too hardcoded at the
      moment. For example, LCD3 is set to use PLL2_1, and PLL2 doesn't exist
      on DRA72x SoCs.
      
      There are quite many ways to configure the clocks, even using HDMI PLL
      for LCD outputs, but enabling full configuration of the clocks is rather
      tricky.
      
      This patch improves the situation a bit by checking if the PLL about to
      be used exists, and if not, tries another one.

      drm/omap: decrease min width & height · 1e90711d
      Tomi Valkeinen authored
      mode_config's min_width and min_height are both set to 32, which is
      overly restrictive.
      
      The real limits depend on whether we're configuring a crtc or a plane,
      but a limit of 8x2 is safe for both cases.

      drm/omap: remove divider constraint from hsdiv · 0e81798e
      Tomi Valkeinen authored
      The driver only uses even dividers for hsdiv when pclk >= 100MHz, as odd
      dividers can create uneven duty cycle. However, while this holds true
      for some dividers like DISPC's LCK and PCK dividers, it is not actually
      true for hsdiv.
      
      hsdiv always produces even duty cycle, so the constraint can be removed.

      drm/omap: refactor CRTC HW property setup · 7e3d9274
      Tomi Valkeinen authored
      The current driver doesn't expose any of the CRTC HW properties like
      background color or transparency key, and sets them at CRTC enable time.
      
      Refactor this into a separate function and call that function from
      omap_crtc_atomic_flush(). This is the behavior we want when the
      properties can be configured, so this patch makes it easier to add
      patches later which implement those properties.

      drm/omap: work-around for errata i886 · 7d267f06
      Tomi Valkeinen authored
      DRA7 errata i886 (FPDLink PLL Unlocks With Certain SoC PLL M/N Values)
      says that FPDLink is sensitive to jitter on the vout clock, and that low
      PLL M and N values result in more jitter than high M and N values.
      
      This patch implements a workaround for the problem by changing the PLL
      setup to search for clocks starting from high M and N values, instead of
      low values. This should not cause any functional change, and only
      reduces the jitter.
