      OMAP: DSS2: Reset LANEx_ULPS_SIG2 bits after use · 8ef0e614
      由 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
      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: OMAPFB: Implement auto-update mode · 27cc213e
      由 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.

      OMAP: DSS2: OMAPFB: Add struct to store per-display data · 065a40bd
      由 Tomi Valkeinen 提交于 
      Create a new struct omapfb_display_data to contain omapfb's private
per-display data. Move the bpp override there.

This struct will be used to hold auto/manual update state of a display
in the following patches.

      OMAP: DSS2: DSI: Change dummy macros to inline functions · 4a9a5e39
      由 Tomi Valkeinen 提交于 
      Using empty macros for performance measurement functions when DSS DEBUG
is not enabled causes an unused variable warning.

Change the empty macros to empty inline functions to remove the
warning.

      OMAP: DSS2: remove extra includes from include/video/omapdss.h · 24e6289c
      由 Tomi Valkeinen 提交于 
      omapdss.h included platform_device.h and atomic.h, neither of which is
needed by omapdss.h. Remove those includes from omapdss.h, and fix the
affected .c files which did not include platform_device.h even though
they should.
