[media] saa7134-i2c: make debug macros to use pr_fmt()
Converting debug prints to use pr_foo() is not trivial, as the
result will be a way worse than what's provided here, due to the
pieces of the code that prints the I2C transfers. Those use a
lot pr_cont(), and, depending on using either level 1 or 2,
a different set of macros are selected.
So, let's replace d1printk() and d2printk() macros by i2c_dbg()
and i2c_count() adding a debug level there.
On media drivers, debugging messages should be grouped into
categories, as this makes easier to debug the driver.
In the case of saa7134, the core has 2 debug categories, one
for IRQ, and another one for the core itself. The IRQ have
actually 2 levels of debug.
So, instead of using pr_dbg(), where everything would be in
the same box, let's define two macros that use pr_fmt(),
one for the core, and another one for irq.
With that, we can replace the remaining printk() occurrences
at the core to use either core_dbg() or irq_dbg(), depending
on the group of debug macros that need to be enabled.

GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner.
It's based on the following components:
- USB bridge: RTL2832P (contains also DVB-T demodulator)
- Demodulator: Si2168-A30
- Tuner: Si2148-A20
The demodulator and the tuner will need firmwares. The Si2148 uses Si2158
firmware. Antti has the firmwares available for download:
http://palosaari.fi/linux/v4l-dvb/firmware/
Do note that for DVB-T either of the demodulators can be used. DVB-C and
DVB-T2 are only supported by the Si2168 demodulator. The driver will
register 2 frontends for the same adapter. Frontend 0 will be the RTL2832
demodulator and frontend 1 will be the Si2168 demodulator. The same
tuner is used for both.
As a consequence of the above, it's recommended to use application that
does implement proper DVBv5 support.

drm: Zero out invalid vblank timestamp in drm_update_vblank_count.
Since commit 844b03f27739135fe1fed2fef06da0ffc4c7a081 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

Pull ARM SoC fixes from Arnd Bergmann:
"A few patches have come up since the merge window. The largest one is
a rewrite of the PXA lubbock/mainstone IRQ handling. This was already
broken in 2011 by a change to the GPIO code and only noticed now.
The other changes contained here are:
MAINTAINERS file updates:
- Ray Jui and Scott Branden are now co-maintainers for some of the
mach-bcm chips, while Christian Daudt and Marc Carino have stepped
down.
- Andrew Victor is no longer maintaining at91. Instead, Alexandre
Belloni now becomes an official maintainer, after having done a
bulk of the work for a while.
- Baruch Siach, who added the mach-digicolor platform in 4.1 is now
listed as maintainer
- The git URL for mach-socfpga has changed
Bug fixes:
- Three bug fixes for new rockchip rk3288 code
- A regression fix to make SD card support work on certain ux500
boards
- multiple smaller dts fixes for imx, omap, mvebu, and shmobile
- a regression fiix for omap3 power consumption
- a fix for regression in the ARM CCI bus driver
Configuration changes:
- more imx platforms are now enabled in multi_v7_defconfig"
