      OMAPDSS: DISPC: print fifo threshold values in bytes · 3cb5d966
      由 Tomi Valkeinen 提交于 
      Fifo thresholds are calculated using bytes, but the debug print prints
values in buffer units. Change the prints to use bytes to be in line
with the calculations, and also to print in the same units on all OMAPs.

      OMAPDSS: APPLY: add fifo-merge support · 1d71f42b
      由 Tomi Valkeinen 提交于 
      Add fifo-merge support. This is done mainly in four functions:
mgr_enable/disable and ovl_enable/disable. These are the functions where
overlays are taken into and out of active use.

The process to enable and disable fifo-merge is not simple. We need to
do it in steps, waiting in between for certain settings to be taken into
use, and continuing after that. The reason for this is that fifo-merge
is a common thing for all managers/overlays, and its use must be
synchronized.

As an example, when we disable an overlay, we first set the overlay as
disabled, then wait until the overlay is actually disabled in the HW,
and only after that we may re-configure the fifos, possibly taking
fifo-merge into use.

      OMAPDSS: APPLY: add fifo merge support funcs · fb011974
      由 Tomi Valkeinen 提交于 
      Add mechanism to set/unset the DISPC fifo-merge:

Add new fields to dss_data, fifo_merge and fifo_merge_dirty. These are
similar to the other info/dirty flags in ovl_priv_data and ovl_mgr_data,
but fifo merge is a common attribute to all managers and thus outside
the ovl_mgr_data.

The fifo-merge field is used in the dss_write_regs_common, which handles
writing the register.

dss_apply_fifo_merge() can be used to set/unset the fifo merge field in
the dss_data.

      OMAPDSS: FEAT: Add FIFO_MERGE feature · e6b0f884
      由 Tomi Valkeinen 提交于 
      Add feature flag for fifo merge. OMAP2 doesn't contain fifo merge, later
OMAPs do.

dispc_enable_fifomerge() checks for the flag when called, and gives a
WARN if fifo merge is being enabled when it is not supported.
