viafb: avoid refresh and mode lookup in set_par

2012-03-08T18:41:38+00:00

As check_var already ensures that the mode is valid there is no need
to do those expensive lookups here again. The only thing that might
change is that the deprecated interface could report slightly
different refresh rates due to rounding errors.

viafb: modetable conversion

2012-03-08T18:41:35+00:00

This patch converts the modetables used in viafb to
- remove the strange thing that sync_end and blanking_end contained
  the length and not the absolute value
- remove hundreds of useless defines
- use fb_videomode and not our own definition so modes defined in
  the subsystem and received via EDID are compatible with ours

As the modes are now stored in a flat structure and no longer in a
tree like thing the lookup time was increased but as it is a rare
event anyway it shouldn't matter. Otherwise the behaviour should be
the same as before.

viafb: LCD bpp cleanup

2012-03-04T12:05:15+00:00

This patch removes redundant bits per pixel information by using the
one storged in var directly. Simplifies code without any functional
changes.

viafb: fix IGA1 modesetting on VX900

2012-02-24T00:38:14+00:00

Even if the documentation calls this bit "Reserved" it has to be set
to 0 for correct modesetting on IGA1.

viafb: select HW scaling on VX900 for IGA2

2012-02-24T00:38:02+00:00

VX900 can do hardware scaling for both IGAs in contrast to previous
hardware which could do it only for IGA2. This patch ensures that
we set the parameter for IGA2 and not for IGA1. This fixes hardware
scaling on VX900 until we have the infrastructure to support it for
both IGAs.

viafb: Fix bug in centering code

2012-02-21T08:50:27+00:00

Obviously this is a typo and although there were no effects observed
it's probably better to fix it.

viafb: another workaround for OLPCs weird wiring

2012-02-21T08:50:19+00:00

On OLPC we must not touch this I2C bus or it will hang.

viafb: NULL dereference on allocation failure in query_edid()

2012-02-17T07:56:21+00:00

We should handle the allocation here, if only to keep the static
checkers happy.
