      drm/omap: display: don't use dsi_get_pixel_size() · 892fdcb0
      Tomi Valkeinen authored
      display.c uses dsi_get_pixel_size() which is implemented in the DSI
      driver, and we won't have that in the omapdss-base module, to which we
      want to move display.c
      
      This patch changes display.c not to use dsi_get_pixel_size(). The call
      can be replaced with a simple check for OMAP_DSS_DSI_FMT_RGB565.
      
      We can also make dsi_get_pixel_size() static as it's no longer used
      outside dsi.c.

      drm/omap: output: use dev_err instead of DSSERR · 39637e10
      Tomi Valkeinen authored
      We don't have omapdss's custom error printing functions in the common
      omapdss-base module, to which we want to move output.c.
      
      This patch changes output.c to use dev_err instead of DSSERR so that it
      doesn't depend on DSSERR.

      drm/omap: move dss_initialized to omapdss-base · 7c299716
      Tomi Valkeinen authored
      omapdss_is_initialized() is used to find out if omapdss has been probed
      successfully. This patch moves the related code to the common
      omapdss-base module, so that the same support will be there for both
      omapdss and omapdss6.

      drm/omap: add omapdss-base.ko · a99ac0d9
      Tomi Valkeinen authored
      We are working towards enabling omapdss6, which will consists of a new
      dss, dispc and dpi drivers. omapdss6 will be a new module. The panel,
      encoder and omapdrm will need to use either the current omapdss driver
      or the new omapdss6 driver, depending on the platform.
      
      This will be implemented with a common base module and function
      pointers.
      
      This patch adds a skeleton omapdss-base.ko module, to which we'll be
      moving common dss functionality like registration of the panels.

      drm/omap: fix HDMI sync polarities · d5e7efad
      Tomi Valkeinen authored
      While implementing writeback support, odd behavior of WBDELAYCOUNT was
      observed with the combination of WB capture and HDMI. The result of the
      debugging was that the HDMI sync polarities are not set correctly.
      
      The current code sets the sync polarities going from HDMI WP to DISPC
      according to the video mode used, which seems to work normally fine, but
      causes problems with WB as WB expects the syncs to be active-high.
      
      This patch changes the HDMI sync polarities so that the DISPC always
      gets active-high syncs from HDMI WP, and the HDMI core gets sync
      polarities according to the used video mode.

      drm/omap: Add support for render nodes · 5f6ab8ca
      Hemant Hariyani authored
      Add support for render nodes in omap driver and allow required
      ioctls to be accessible via render nodes.
      
      This enables unprivileged clients to allocate resources like GEM buffers
      for rendering their content into. Mode setting (KMS ioctls) is not
      allowed using render nodes. These buffers are then shared with
      a previleged process (e.g compositor) that has mode setting access.
      
      An example of this use case is Android where the hardware composer is
      the only master and has mode setting access. Every other client then
      uses render node(e.g /dev/dri/renderD128 to allocate and use its buffers.

      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.
