This creates read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for
reading and updating those registers.  It creates gxfb.h to house these.

We also drop a no-op readl() from gx_set_mode.  Other than that, there should
be no functionality change.

Use a command line option (vram) rather than hardcoding the vram size.  LxFB
already does this; it's useful for machines that can't query the BIOS for fb
size.  This patch originated from David Woodhouse, was modified by Jordan
Crouse, and was then modified further by me.

This also adds some gxfb documentation in Documentation/fb.

While running in flatpanel mode it is important to change the FP sync bits (VG
register 0x408) rather then the CRT sync bits (VG register 0x008).  This patch
keeps the CRT sync bits at default when a flatpanel exists.

Note that this also fixes inverted logic; we want CRT_VSYNC_POL to be set (ie,
vsync is normally high) when FB_SYNC_VERT_HIGH_ACT is unset.

This is generic VSA2 detection.  It's used by OLPC to determine whether or not

This cleans up a few MSR-using drivers in the following manner:
  - Ensures MSRs are all defined in asm/geode.h, rather than in misc
    places
  - Makes the naming consistent; cs553[56] ones begin with MSR_,
    GX-specific ones start with MSR_GX_, and LX-specific ones start
    with MSR_LX_.  Also, make the names match the data sheet.
  - Use MSR names rather than numbers in source code
  - Document the fact that the LX's MSR_PADSEL has the wrong value
    in the data sheet.  That's, uh, good to note.

Currently, if a perfect match in terms of resolution is not found,
fb_find_mode() only looks for a best-fit mode among modes with a higher
resolution than the one requested.  Thus, if the user requests a resolution
higher than the largest supported one, they are dropped to the default mode
(usually a low resolution one).

Change this behaviour so that all valid video modes are considered when
looking for a best-fit mode, while still preferring modes with a higher
resolution.

If gpio_chip->base is negative during registration, gpiolib performs dynamic
base allocation.  This is useful for devices that aren't always present, such
as GPIOs on hotplugged devices rather than mainboards.  (This behavior was
previously specified but not implemented.)

To avoid using any numbers that may have been explicitly assigned but not yet
registered, this dynamic allocation assigns GPIO numbers from the biggest
number on down, instead of from the smallest on up.

As long as one or more GPIOs on a gpio chip are used its driver should not be
unloaded.  The existing mechanism (gpiochip_remove failure) doesn't address
that, since rmmod can no longer be made to fail by having the cleanup code
report errors.  Module usecounts are the solution.

Assuming standard "initialize struct to zero" policies, this change won't
affect SOC platform drivers.  However, drivers for external chips (on I2C and
SPI busses) should be updated if they can be built as modules.
