      fbdev: section cleanup in viafb driver · eca9c47b
      Henrik Kretzschmar authored 
      This patch moves two functions from .devexit to .text,
which are called on the probe error path.
Also a function which is called by probe is moved
from .text to .devinit.

WARNING: vmlinux.o(.devinit.text+0x2ca5): Section mismatch in reference
from the function via_pci_probe() to the function
devexit.text:via_teardown_subdevs()
The function __devinit via_pci_probe() references
a function __devexit via_teardown_subdevs().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
via_teardown_subdevs() so it may be used outside an exit section.

WARNING: vmlinux.o(.devinit.text+0x2cb1): Section mismatch in reference

The function __devinit via_pci_probe() references

      viafb: fix accel_flags check_var bug

In check_var we should check and modify the var given and not the
one which is currently active. So this code was obviously wrong.
Probably this was doing no harm because all acceleration functions
also check whether acceleration is possible. (otherwise I would
expect this to lead to a null pointer dereference)

      viafb: remove ioctls which break the framebuffer interface

The ioctls VIAFB_SET_DEVICE, VIAFB_SET_DEVICE_INFO and
VIAFB_SET_SECOND_MODE are removed because they prevent a clean
framebuffer driver because they modify the hardware and/or the
internal structures.
There are no known applications using these ioctls so no breakage is
expected. Additionaly the main functionality was duplicating the
framebuffer interface so there really should not exist any user.

      viafb: update fix before calculating depth

As the depth calculation depends on information in fix it is saner to
do the update first.
No runtime change expected as the value visual in fix used never
changes to MONO.

      viafb: PLL value cleanup · 1f844350
      Florian Tobias Schandinat authored 
      viafb: PLL value cleanup

This is a big change of how PLL values are handled on the road to
dynamic PLL value generation. The table was converted automatically in
the relevant parameters for frequency generation. Sadly there were some
bits set whose meaning is unknown. Those differences are documented
but ignored as the unichrome code implies that they are not important
(a big thanks to Luc for his amazing work).
The PLL values for 31490000 and 133308000 are deleted as they were more
than 5% off and not used anyway. The values for CX700@60466000 and
VX855@153920000 are corrected as they were wrong and easily correctable
as enough correct values was available because CX700 and VX855 support
the same values only with a little difference in hardware format.
All remaining values are not more than 2% off.
Additionally the surrounding code is changed as needed especially the
byte order of the values written to hardware to allow nicer conversion
functions.
This is mostly a change preparing for dynamic PLL generation and the two
corrected values aside no runtime change is expected.

      viafb: simplify lcd size "detection"

Remove all occurences of get_lcd_size_method as only the values
GET_LCD_SIZE_BY_VGA_BIOS and GET_LCD_SIZE_BY_USER_SETTING were used
which had the identical code so there is no need to make things look
more complicated than they actually are.
Just a bit of of cleanup, really no regressions expected.

      viafb: fix PCI table

This patch fixes an oddity in the device table where the P4M890 ID was
assigned with the enumeration value of CN700 which itself was missing.
This is a regression introduced by
	"viafb: make viafb a first-class citizen using pci_driver"

While at it reorder the table to reflect the order of the  enumeration
values.

      viafb: add lcd scaling support for some IGPs

These IGPs should also support lcd scaling but likely this switch was
missed when adding support for them. Fix it, allowing lcd scaling on
CN750, VX800 and VX855. At least this improves the situation for
VX855. (there seems to be another scaling unrelated bug somewhere)

      viafb: remove duplicated scaling code

The code for P4M900 does the same as for all newer IGPs so there is no
reason to duplicate it. Just reducing the code to maintain.
