      OMAP: DSS2: Fix FIFO threshold and burst size for OMAP4 · 5ed8cf5b
      Tomi Valkeinen 提交于
      The DMA FIFO threshold registers and burst size registers have changed
      for OMAP4.  The current code only handles OMAP2/3 case, and so the
      values are a bit off for OMAP4.  A summary of the differences between
      OMAP2/3 and OMAP4:
      
      Burst size:
      OMAP2/3: 4 x 32 bits / 8 x 32 bits / 16 x 32 bits
      OMAP4: 2 x 128 bits / 4 x 128 bits / 8 x 128 bits
      
      Threshold size:
      OMAP2/3: in bytes (8 bit units)
      OMAP4: in 128bit units
      
      This patch fixes the issue by creating two new helper functions in
      dss_features: dss_feat_get_buffer_size_unit() and
      dss_feat_get_burst_size_unit(). These return (in bytes) the unit size
      for threshold registers and unit size for burst size register,
      respectively, and are used to calculate correct values.
      
      For the threshold size the usage is straightforward. However, the burst
      size register has different multipliers for OMAP2/3 and OMAP4. This
      patch solves the problem by defining the multipliers for the burst size
      as 2x, 4x and 8x, which fit fine for the OMAP4 burst size definition
      (i.e. burst size unit for OMAP4 is 128bits), but requires a slight twist
      on OMAP2/3 by defining the burst size unit as 64bit.
      
      As the driver in practice always uses the maximum burst size, and no use
      case currently exists where we would want to use a smaller burst size,
      this patch changes the driver to hardcode the burst size when
      initializing DISPC. This makes the threshold configuration code somewhat
      simpler.

      OMAP: DSS2: DSI: sync when disabling a display · 15ffa1da
      Tomi Valkeinen 提交于
      When the panel driver calls omapdss_dsi_display_disable() it is possible
      that there are still some unsent packets in the TX fifo.
      
      Add dsi_sync_vc() calls in the beginning of
      omapdss_dsi_display_disable() to make sure the TX fifos are empty.
      
      This allows us to remove the msleep(10) hack from panel-taal.c

      OMAP: DSS2: Reset LANEx_ULPS_SIG2 bits after use · 8ef0e614
      Tomi Valkeinen 提交于
      LANEx_ULPS_SIG2 bits are left on after entering ULPS. This doesn't cause
      any problems currently, as DSI HW is reset when it is enabled. However,
      if the reset is not done, operation fails if the bits are still set.
      
      So reset the bits after entering ULPS to ensure operation even without
      HW reset.

      OMAP: DSS2: Taal: Make driver more fault tolerant · e8945677
      Tomi Valkeinen 提交于
      If ULPS exit fails, and the following reset fails also, Taal driver was
      left in state where it thinks DSI is enabled while it really isn't,
      leading to crash.
      
      This patch checks the return value of taal_panel_reset, and if that
      fails, ulps_enabled is left true, causing the driver to retry ulps exit
      later.
      
      Also the return value of taal_wake_up is checked at taal_disable, and if
      wake up fails, we'll skip the power_off. This could leave the panel into
      a not-quite-valid state, but there's nothing we can do about it in that
      situation.

      OMAP: DSS2: OMAPFB: Implement auto-update mode · 27cc213e
      Tomi Valkeinen 提交于
      Implement auto-update mode for manual-update displays. omapfb driver
      uses a delayed work to update the display with a constant rate.
      
      The update mode can be changed via OMAPFB_SET_UPDATE_MODE ioctl, which
      previously called omapdss but is now handled inside omapfb, and a new
      sysfs file, "update_mode".
      
      The update interval is by default 20 times per second, but can be
      changed via "auto_update_freq" module parameter. There is also a new
      module parameter "auto_update", which will make omapfb start manual
      update displays in auto-update mode.
      
      This auto-update mode can be used for testing if the userspace does not
      support manual update displays properly. However, it is a very
      inefficient solution, and should be considered more as a hack for
      testing than something that could be used as a long term solution.

      Add the support for NV12 color format.
      Configure base address for UV component of NV12 color format.
      Change the way chroma scaling is handled for YUV formats on OMAP4 by enabling
      chroma-resampling for video pipeline and hence using FIR2 register set for
      scaling UV.
      Changes to _dispc_set_scaling(), because of the reason above, are:
      - call _dispc_set_scaling_common() to handle scaling for all color formats
        except for OMAP4 where it only handles scaling for RGB or Y-component
      - call _dispc_set_scaling_uv() for special handling required for UV
        component on OMAP4.
      - dispc_set_scaling_uv() also resets chroma-resampling bit for RGB color modes.

      - FIR registers used for UV-color-component scaling on OMAP4
      - Accumulator registers used for UV-color-component scaling
      Add these new registers to save/restore and DUMPREG functions.
      Also add two new features for OMAP4:
      - FEAT_HANDLE_UV_SEPARATE - this is used on OMAP4 as UV color-component requires
        separate handling.
      - FEAT_ATTR2 - this is used on OMAP4 to configure new ATTRIBUTES2 register.

      OMAP: DSS2: Ensure non-zero FIR values are configured · ed14a3ce
      Amber Jain 提交于
      FIR values can never be zero as per TRM, and the current code writes zero
      when scaling is not used. It was not causing any problem as scaling was
      disabled when zero was written. Its still safer to not write zero to
      it in any case.
      Now we configure correct FIR values even when scaling is not used (i.e. set FIR
      to 1024 when scaling is not used), but the scaling enable bits are still kept
      off if the scaling is not needed.
