      OMAP: DSS2: Fix FIFO threshold and burst size for OMAP4 · 5ed8cf5b
      由 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
      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

CPR is enabled via manager?/cpr_enable file, and the coefficient matrix
is set via manager?/cpr_coef file. The values in cpr_coef are in the
following order:

      OMAP: DSS2: Add FEAT_VENC_REQUIRES_TV_DAC_CLK · 525dae61
      由 Tomi Valkeinen 提交于 
      OMAP3430 requires an 96MHz clock to VENC's DAC, but no other OMAP needs
it.

Add a new feature, FEAT_VENC_REQUIRES_TV_DAC_CLK, which tells if the
clock is needed on this platform, and use that feature in venc.c to
decide if the clock needs enabling.

      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: 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.
