      OMAP: DSS2: Create an enum for DSI pixel formats · a3b3cc2b
      由 Archit Taneja 提交于 
      Currently, DSI pixel info is only represented by the pixel size in bits using
the pixel_size parameter in omap_dss_device struct's ctrl member.

This is not sufficient information for DSI video mode usage, as two of the
supported formats(RGB666 loosely packed, and RGB888) have the same pixel
container size, but different data_type values for the video mode packet header.

Create enum "omap_dss_dsi_pixel_format" which describes the pixel data format
the panel is configured for. Create helper function dsi_get_pixel_size() which
returns the pixel size of the given pixel format.

Modify functions omapdss_default_get_recommended_bpp() and dss_use_replication()
to use dsi_get_pixel_size().

      OMAP: DSS2: Use MIPI DSI enums from include/video/mipi_display.h · 7a7c48f9
      由 Archit Taneja 提交于 
      MIPI DSI Transaction types and DCS commands are currently defined as
macros in dsi.c and panel-taal.c, remove these and replace them with
enum members defined in include/video/mipi_display.h.

      OMAP: DSS2: DSI: sync when disabling a display · 15ffa1da
      由 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: Taal: Make driver more fault tolerant · e8945677
      由 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: remove update_mode from omapdss · 8cff88c5
      由 Tomi Valkeinen 提交于 
      Remove the whole update_mode stuff from omapdss driver. If automatic
update for manual update displays is needed, it's better implemented in
higher layers.

      OMAP: DSS2: Use request / release calls in Taal for DSI Virtual Channels. · bc6d4b1d
      由 Archit Taneja 提交于 
      Taal driver used to take a hard coded Macro for Virtual Channel and the VC_ID.
The Taal panel driver now requests for a Virtual channel through the
omap_dsi_request_vc() call in taal_probe().

The channel number returned by the request_vc() call is used for sending command
and data to the Panel. The DSI driver automatically configures the Virtual
Channel's source to either Video Port or L4 Slave port based on what the panel
driver is using it for.

The driver uses omap_dsi_release_vc() to free the VC specified by the panel.
taal_remove() or when a request_vc() call fails.
