128-byte pitch alignement is not a hardware feature, it's a hardware
bug. Split it from the features field into a new quirks field. New
quirks will be added to support the R8A7791 SoC.

When setting a new frame buffer with the mode set base operation the
pitch value might change. Set the hardware plane pitch register at the
same time as the plane base address in the rcar_du_plane_update_base()
function to make sure the pitch value always matches the frame buffer.

In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR(). Also remove the dev_err call to avoid redundant
error message.

We moved minor deallocation to drm_dev_free() in:

  Date:   Sun Oct 20 18:55:45 2013 +0200

      drm: delay minor destruction to drm_dev_free()

However, this causes a call to drm_unplug_minor(), which should just do
nothing as drm_dev_unregister() already called this.

But a separate patch caused kdev lifetime changes:

      drm/sysfs: sort out minor and connector device object lifetimes.

Thus making our dev_is_registered() call useles (and even segfault if it
is NULL). Replace it with a simple !kdev test and we're fine.

The vrefresh field of the mode is 0 for most modes
fetched from the EDID (e.g., established timings).
When dealing with monitors that have a bogus preferred
mode, we may not always select the mode we want because
we compare the target refresh to the mode's vrefresh which
is 0 in a lot of cases.

This reverts commit 555b1b65.

Let's try this again for 3.13.  It's required for proper
interaction with alsa.  Was disabled previously in 3.12
to be on the safe side since it caused problems on older
asics.

In order to have any realistic chance of calculating proper
ACR values, we need to be able to calculate both N and CTS,
not just CTS. We still aim for the ideal N as specified in
the HDMI spec though.

The values were taken from the HDMI spec, but they assumed
exact x/1.001 clocks. Since we round the clocks, we also need
to calculate different N and CTS values.

Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of
spec. Hopefully this mode is rarely used and/or HDMI sinks
tolerate overly large values of N.
