Adding support for the CX23888 DIF.
Changes regression tested against the HVR1700 and HVR1800.
Split out much of the set and init handling of the cx23885 based
cards into their own functions. Added the DIF initialization code
for each supported IF.
Updated the cx23885 code to correctly initialize cx23888 based
video/audio decoders.
Enabled Closed Caption support for CX23885 based cards during
initialization.

Added three new control calls (g_std, querystd and g_ctrl) to
the -417 driver. Also routed other controls through the main
cx23885 driver meaning that the controls for the 417 and the
raw video device all enter the driver code and are handled

First in a series of patches that adds support to the cx23885 driver
for CX23888 analog video handling. Raw and MPEG video support is
being added for the HVR1850 driver in the patch, and the following
series of patches.
Some basic cx23885 driver cleanup. Partly to add HVR1850 support
and partly to allow -417.c V4L2 calls to be routed through thr
driver core and handled in a single place.
Make a number of core driver functions available to the -417.c
driver to streamline the driver.
Add the analog tuner ops definition so we can reach/tune the
hardware when we need to. Added the tff field so 888 based cards
(which have a weird field ordering issue) can be accomodated
and worked around in the driver.

The CX23888 (HVR1850 and other new cards) contain a DIF which is responsible
for demodulating the audio and video. It's built directly into the CX23888
PCIe bridge. It needs to be enabled and disabled on a per-card and per-input
basis. We pass this flag from the cx23885 core driver to the sub-device
when we need the cx25840 driver to enable/disable with the DIF correctly.

The function hdmi_audio_trigger is a callback used by ASoC to stop/start

Hence, it should be placed in the general portion of the HDMI driver,

Also, make this function static.

These functions require access to IP-secific data. However, it is not possible
to pass such data as a function argument as such functions have a specific
signature specified by ASoC. Instead, they will have access to the IP-specific
data by calling snd_soc_codec_get_drvdata. The codec driver data is set
at probe time.

Under the new DSS architecture for HDMI, there is a clear separation
between general DSS code and HDMI IP-specific data. Functions
that require access to the HDMI driver IP-specific data receive an
hdmi_ip_data structure. The ASoC codec require access to such
IP-specific data. Then, instead of accessing it directly, it will be
passed as codec driver data. This also helps to have a clear separation
between DSS and ASoC portions of the code.

As has been discussed many times[1], Using NO_IRQ set to anything other
than 0 is bug waiting to happen since many drivers follow the pattern
"if (!irq)" for testing whether or not an irq has been set.
This patch changes the Microblaze NO_IRQ setting from -1 to 0 to bring
it in line with most of the rest of the kernel. It also prepares for
Microblaze eventually supporting multiple interrupt controllers by
breaking the assumption that hwirq# == Linux IRQ#. The Linux IRQ
number is just a cookie with no guarantee of a direct relationship
with the hardware irq arrangement.
At this point, Microblaze interrupt handling only supports only one
instance of one kind of interrupt controller (xilinx_intc). This change
shouldn't affect any architecture code outside of the interrupt
controller driver and the irq_of mapping.
Updated to 3.2 and to use irq_data.hwirq by Rob Herring.
Tested and fixed by Michal Simek.

The main reason is that this generic function calls irq_create_of_mapping

process sometimes hangs indefinitely in jbd2_journal_lock_updates().
Toshiyuki identified that the following race happens:
jbd2_journal_lock_updates() |jbd2_journal_stop()
---------------------------------------+---------------------------------------
write_lock(&journal->j_state_lock) | .
++journal->j_barrier_count | .
spin_lock(&tran->t_handle_lock) | .
atomic_read(&tran->t_updates) //not 0 |
| atomic_dec_and_test(&tran->t_updates)
| // t_updates = 0

prepare_to_wait() | // no process is woken up.
spin_unlock(&tran->t_handle_lock) |
write_unlock(&journal->j_state_lock) |
schedule() // never return |
We fix the problem by first calling prepare_to_wait() and only after that
checking t_updates in jbd2_journal_lock_updates().

The REBOOT_TYPE may be either grub or script, if it is script
it is expected that a REBOOT_SCRIPT is defined.
With the SWITCH_TO_TEST which is the complement of SWITCH_TO_GOOD,
which does basically the same thing as REBOOT_SCRIPT and but for
both grub and script, the REBOOT_SCRIPT does not need to be mandatory
anymore.
Do not require the REBOOT_SCRIPT and always run the reboot code
