When performing a modeset, use the framebuffer pitch value to set FIMD
IMG_SIZE and Mixer SPAN registers. These are both defined as pitch - the
distance between contiguous lines (bytes for FIMD, pixels for mixer).

The legcy colorkey ioctls are only implemented for sprite planes, so
reject the ioctl for primary/cursor planes. If we want to support
colorkeying with these planes (assuming we have hw support of course)
we should just move ahead with the colorkey property conversion.

A few more fixes for 4.0 for radeon.  Sorry for the delay, I was
a little under the weather this week and time got away from me.

Pull ARM SoC fixes from Olof Johansson:
 "The latest and greatest fixes for ARM platform code.  Worth pointing
  out are:

   - Lines-wise, largest is a PXA fix for dealing with interrupts on DT
     that was quite broken.  It's still newish code so while we could
     have held this off, it seemed appropriate to include now

   - Some GPIO fixes for OMAP platforms added a few lines.  This was
     also fixes for code recently added (this release).

   - Small OMAP timer fix to behave better with partially upstreamed
     platforms, which is quite welcome.

   - Allwinner fixes about operating point control, reducing
     overclocking in some cases for better stability.

  plus a handful of other smaller fixes across the map"

Fixes for omaps for the -rc cycle:

- Fix a device tree based booting vs legacy booting regression for

- Fix /sys/bus/soc/devices/soc0/family for am33xx devices.

The UART reference clock speed is 7273.8 kHz, not 72738 kHz.

Dots aren't usually used in node names even though ePAPR permits
them.  However, this can easily be avoided by expressing the
frequency in Hz, not kHz.

This patch changes the name to refclk7273800hz, reflecting the
actual clock speed.

If the user supplies EDID through firmware or debugfs override, the
driver callbacks are bypassed and the connector ELD does not get
updated, and audio fails. Set ELD for firmware and debugfs EDIDs too.

There should be no harm in gratuitously doing this for non HDMI/DP
connectors, as it's still up to the driver to use the ELD, if any.

The IMG PDC watchdog driver heartbeat module parameter has no default so
it is initialised to zero. This results in the following warning during
probe:

imgpdc-wdt 2006000.wdt: Initial timeout out of range! setting max timeout

The module parameter description implies that the default value should
be PDC_WDT_DEF_TIMEOUT, which isn't yet used, so initialise it to that.

Also tweak the heartbeat module parameter description for consistency.

The IMG PDC watchdog probe function calls pdc_wdt_stop() prior to
watchdog_set_drvdata(), causing a NULL pointer dereference when
pdc_wdt_stop() retrieves the struct pdc_wdt_dev pointer using
watchdog_get_drvdata() and reads the register base address through it.

Fix by moving the watchdog_set_drvdata() call earlier, to where various
other pdc_wdt->wdt_dev fields are initialised.
