This patch updates the PFC code with some clarifying

Fix divide by zero and broken output. Commit 600ce1a0fa ("fix clock
setting for Samsung SoC Framebuffer") introduced a mandatory refresh
parameter to the platform data for the S3C framebuffer but did not
introduce any validation code, causing existing platforms (none of which
have refresh set) to divide by zero whenever the framebuffer is
configured, generating warnings and unusable output.Ben Dooks noted several problems with the patch:
- The platform data supplies the pixclk directly and should already
have taken care of the refresh rate.
- The addition of a window ID parameter doesn't help since only the
root framebuffer can control the pixclk.
- pixclk is specified in picoseconds (rather than Hz) as the patch
assumed.and suggests reverting the commit so do that. Without fixing this no
mainline user of the driver will produce output.[akpm@linux-foundation.org: don't revert the correct bit]

Many platform support this feature, and it can provide significant
power savings when the reduced refresh rate is low. However, on some
platforms a secondary (reduced) timing is provided but not actually
supported by the hardware. This results in undesirable flicker at
runtime.So disable the feature by default, but allow users to opt-in to the
reduced clock behavior with a new module parameter, lvds_downclock,
that can be set to 1 to enable the feature.Signed-off-by: Jesse Barnes

There are some tg3 devices that require the driver to post new rx
buffers in smaller increments. Commit
4361935afe3abc3e5a93006b99197fac1fabbd50, "tg3: Consider
rx_std_prod_idx a hw mailbox" changed how the driver tracks the rx
producer ring updates, but it does not make any special considerations
for the above-mentioned devices. For those devices, it is possible for
the driver to hit the special case path, which updates the hardware
mailbox register but skips updating the shadow software mailbox member.
If the special case path represents the final mailbox update for this
ISR iteration, the hardware and software mailbox values will be out of
sync. Ultimately, this will cause the driver to use a stale mailbox
value on the next iteration, which will appear to the hardware as a
large rx buffer update. Bad things ensue.The fix is to update the software shadow mailbox member when the special
case path is taken.Signed-off-by: Matt Carlson
