      drm/omap: display: Add displays in sorted order to the panel_list · 389c5763
      Peter Ujfalusi authored
      Keep the panel_list ordered according to aliases. The DRM connectors will
      be created following the panel_list. By keeping the list ordered the DRM
      connectors will be created in the same order regardless of the driver
      probe order.

      drm/omap: Use omapdss_stack_is_ready() to check that the display stack is up · a09d2bc1
      Peter Ujfalusi authored
      Instead of 'guessing' based on aliases of the status of the DSS drivers,
      use the new interface to check that all needed drivers are loaded.
      In this way we can be sure that all needed drivers are loaded so it is
      safe to continue the probing of omapdrm.
      This method will allow the omapdrm to be probed 'headless', without
      outputs.

      drm/omap: dss: Support for detecting display stack readiness · 1e08c822
      Peter Ujfalusi authored
      When omapdss is loaded (all core components are in place) create a list of
      devices used in the display graph. This list later can be used by omapdrm
      via the omapdss_stack_is_ready() function to check that these components
      are loaded. Based on this information, omapdrm can defer probe in case when
      the omapdss stack is not ready yet.

      drm/omap: dss: Functions to check components in the display/output list · 7c79e8d6
      Peter Ujfalusi authored
      The functions can be used to check a component (by it's of_node) if it is
      part of the omapdss display or output list. If the component is found, it
      means that the driver is loaded.

      drm/omap: fix replication logic · be2d68c6
      Tomi Valkeinen authored
      DSS uses "replication logic" to convert color components from smaller
      bit widths to bigger bit widths. Without replication logic, the color
      component would be shifted and the least significant bits would be left
      at 0, whereas with replication logic, the least significat bits will be
      filled with the most significant bit.
      
      For some reason omapdrm leaves replication logic always to off, which,
      in the most common case, means that showing 16-bit RGB colors on 24-bit
      display gives a bit darker colors than expected.
      
      The reset value of the replication logic bit is enabled, and it should
      always be set, as there's no practical reason to disable it. This patch
      removes the option to disable it from omapdrm, and always sets it to
      enabled in dispc.

      drm/omap: remove all EXPORT_SYMBOLs from dispc.c · 5034b1fa
      Tomi Valkeinen authored
      omapdrm now uses dispc_ops instead of direct function calls so we can

      made static, but a few are used outside dispc.c.

      drm/omap: use dispc_ops · 9f759225
      Tomi Valkeinen authored
      Change omapdrm to get dispc_ops and use that to call the dispc functions
      instead or direct function calls.
      
      The change is very straightforward.
      
      The only problem was in omap_crtc_init() which calls pipe2vbl(crtc), and
      at that point of time the crtc->dev link, which is used to get the
      dispc_ops, has not been set up yet. This patch makes omap_crtc_init()
      skip the call to pipe2vbl() and instead calls
      dispc_ops->mgr_get_vsync_irq() directly.

      drm/omap: move dispc related dss-feat funcs to dispc · c283400a
      Tomi Valkeinen authored
      omapdrm still uses a few non-dispc functions: dss_feat_get_num_mgrs(),
      dss_feat_get_num_ovls() and  dss_feat_get_supported_color_modes(). We
      want to provide omapdrm a single dispc_ops function pointer struct so
      that omapdrm will use either the current omapdss or the new omapdss6
      driver depending on the platform.
      
      Those three functions are really dispc functions, but are located in the
      dss_features.c for legacy reasons.
      
      This patch adds similar functionss to the dispc, and changes omapdrm to
      use those new functions. Underneath the functions still call the
      functions from dss_feature.c.

      We are working towards enabling omapdss6, which will consists of a new

      This will be implemented with a common base module and function
      pointers.

      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: 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.

      The current driver doesn't expose any of the CRTC HW properties like

      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.
