So, having read through the entire thread I *think* this is what the
status of this patchset is:
1. Patches 1-17 are noncontroversial, Raghavendra is going to send an
update split into two patchsets;
2. There are at least two versions of patch 15; I think the "PATCH
RESEND RFC" is the right

The video-input-port (VIP) is highly configurable. This prepares
current driver to allow to configure VIP configuration, as some
boards connect lcd controller and TDA998x "pin-swapped" and depend
on VIP to swap the pins by register configuration.

Some LCD controller cannot provide valid VESA style sync, i.e. coincident
HS/VS edges. First, this patch adds hskew passed from the adjusted_mode to
reference pixel calculation to allow those controllers to add an offset
relative to the expected reference pixel.
From: Darren Etheridge
Add a fixup function that will flip the hsync priority and
add a hskew value that is used to shift the tda998x to the
right by a variable number of pixels depending on the mode.
This works around an issue with the sync timings that tilcdc
is outputing.

This patch seems to fix the garbage at the end problem. Booting an
old kernel and using openssl decodes them OK.
Still have problems booting if there are any compressed images in ERST
to be inflated.

From the backtrace I have no idea if this was from the aio code using it
or the cgroup code - Sasha, any idea?
AIO is probably more likely, I'm going to look to see if I can find
anything...

These changes add new features and fix bugs in the Tilera PCI
root complex subsystem. Among the new tilegx features are support
for I/O space access, more MXI-X interrupt vectors, and support for
TRIO 0 MAC 0 on Gx72 systems.
Chris Metcalf (20):
tile PCI RC: cleanups for tilepro PCI RC
tile
The TRIO shim initialization is shared with other kernel drivers
such as the endpoint and StreamIO drivers, so reorganize the
initialization flow to ensure that the root complex driver properly
initializes TRIO state regardless of what kind of TRIO driver will
end up using the shim.
Allow longer delays if requested, and print the info messages
as we are performing the delay, not when parsing the arguments.

To support PCIe devices with higher number of MSI-X interrupt vectors,
e.g. 16 for the LSI RAID card, enhance the Gx RC stack to provide more
MSI-X vectors by using the TRIO Scatter Queues, which provide 8 more
vectors in addition to ~10 from the Map Mem regions.

If we are rebooting (e.g. via kexec) then the PCI RC link may
already be up. In that case, we don't want to do the software
fixup to force the link up, since that can degrade it to Gen1.

The divider width used to be hardcoded. Some A31 dividers are no longer

we will introduce the sun6i (A31) clocks.
