cs5535: define lxfb/gxfb MSRs in linux/cs5535.h

2009-12-15T16:53:28+00:00

..and include them in the lxfb/gxfb drivers rather than asm/geode.h (where
possible).

gx1fb: properly alloc cmap and plug cmap leak

2009-02-11T22:25:34+00:00

We weren't properly allocating the cmap for depths greater than 8bpp,
which caused pain for things like DirectFB.  Also, we never freed the cmap
memory upon module unload..

pci: use pci_ioremap_bar() in drivers/video

2009-01-06T23:59:26+00:00

Use the newly introduced pci_ioremap_bar() function in drivers/video.
pci_ioremap_bar() just takes a pci device and a bar number, with the goal
of making it really hard to get wrong, while also having a central place
to stick sanity checks.

lxfb: fix console blanking

2008-07-24T17:47:40+00:00

Simply enabling DAC blanking without turning off the CRT seems to be resulting
in characters remaining on the screen when the monitor blanks.  This patch
turns off the CRT for all modes, and also powers down the DACs when vsync
and/or hsync are disabled.

lxfb: drop dead declarations from header

2008-07-24T17:47:40+00:00

We never sent the gamma stuff upstream, and don't really care about it.
However, lx_[gs]_et_gamma prototypes snuck into lxfb.h anyways; there are
no definitions for them.  Drop the dead code.

fix "lxfb: extend PLL table to support dotclocks below 25 MHz"

2008-05-15T02:11:13+00:00

The following patch caused a regression with OLPC panels:

 commit 3888d4639e78802c4ec1086127124e890461b9e4
    lxfb: extend PLL table to support dotclocks below 25 MHz

    Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to
    make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25
    MHz.  These are needed for small LCDs (e.g.  320x240).  Also inserts some
    intermediate steps between pre-existing frequencies.

The problem was the insertion of intermediate steps into the frequency
table; they would cause the wrong frequency to be matched.  This patch
drops those intermediate frequencies while keeping the sub-25MHz
frequencies.
