Add a new device table that contains information that can be checked
at runtime in order to decide which configuration to use. This allows
us to map the full cfg independently from the tran-specific

With the new concept of separating the trans-specific (trans_cfg) data
from the rest of the cfg, we will start mapping only the trans_cfg
part to the PCI device ID/subsystem device ID. So we can assume that
the data passed to the probe function contains the trans_cfg, but
since the full cfg still contains the trans_cfg at the beginning, we
can allow a full cfg to be passed as well. This makes it easier to
convert the existing tables one by one.

We have many different firmware images with the same version,
and it's sometimes cumbersome to figure out which image was
really used, especially as the marketing strings that we do
print out can be the same for (slightly) different hardware
using different firmware images.
Incorporate the firmware filename into the fw_version so it's
printed out all the time. Unfortunately, this will make the
string be longer than the 32 characters for ethtool, but we
almost never really use ethtool, so strip the "iwlwifi-"
prefix (if not overridden), and the remaining data that may
then be stripped at the end is not usually useful anyway.

The current implementation of ALSA control API fully relies on the
callbacks of each driver, and there is no verification of the values
passed via API. This patch is an attempt to improve the situation
slightly by adding the validation code for the values stored via info
and get callbacks.
The patch adds a new kconfig, CONFIG_SND_CTL_VALIDATION. It depends
on CONFIG_SND_DEBUG and off as default since the validation would
require a slight overhead including the additional call of info
callback at each get callback invocation.
When this config is enabled, the values stored by each info callback
invocation are verified, namely:
- Whether the info type is valid
- Whether the number of enum items is non-zero
- Whether the given info count is within the allowed boundary
Similarly, the values stored at each get callback are verified as
well:
- Whether the values are within the given range
- Whether the values are aligned with the given step
- Whether any further changes are seen in the data array over the
given info count
The last point helps identifying a possibly invalid data type access,
typically a case where the info callback declares the type being
SNDRV_CTL_ELEM_TYPE_ENUMERATED while the get/put callbacks store
the values in value.integer.value[] array.
When a validation fails, the ALSA core logs an error message including
the device and the control ID, and the API call also returns an
error. So, with the new validation turned on, the driver behavior
difference may be visible on user-space, too -- it's intentional,
though, so that we can catch an error more clearly.
The patch also introduces a new ctl access type,
SNDRV_CTL_ELEM_ACCESS_SKIP_CHECK. A driver may pass this flag with
other access bits to indicate that the ctl element won't be verified.
It's useful when a driver code is specially written to access the data
greater than info->count size by some reason. For example, this flag
is actually set now in HD-audio HDMI codec driver which needs to clear
the data array in the case of the disconnected monitor.
Also, the PCM channel-map helper code is slightly modified to avoid
the false-positive hit by this validation code, too.

The A10/A20 Allwinner SoCs have two camera sensor interface blocks,
named CSI0 and CSI1. The two have the same register layouts with
slightly different features:
- CSI0 has an image signal processor (ISP); CSI1 doesn't
- CSI0 can support up to four separate channels under CCIR656;
CSI1 can only support one
- CSI0 can support up to 16-bit wide bus with YUV422;
CSI1 can support up to 24-bit wide bus with YUV444
For now the driver doesn't support wide busses, nor CCIR656. So the
only relevant difference is whether a clock needs to be taken and
enabled for the ISP.
Add structs to record the differences, tie them to the compatible
strings, and deal with the ISP clock. Support for the new CSI1
hardware block is added as well.

scheme without the DRAM starting offset.
Deal with this using the "interconnects" property from the device tree,

The Allwinner camera sensor interface has a different definition of
[HV]sync. While the timing diagram uses the names HSYNC and VSYNC,
the note following the diagram and register names use HREF and VREF.
Combined they imply the hardware uses either [HV]REF or inverted
[HV]SYNC. There are also registers to set horizontal skip lengths
in pixels and vertical skip lengths in lines, also known as back
porches.
Fix the polarity handling by using the opposite polarity flag for
the checks. Also rename `[hv]sync_pol` to `[hv]ref_pol` to better

This driver supports both the mt9v032 (color) and the mt9v022 (mono)
sensors. Depending on which sensor is used, the format from the sensor is
different. The format.code inside the dev struct holds this information.
The enum mbus and enum frame sizes need to take into account both type of
sensors, not just the color one. To solve this, use the format.code in
these functions instead of the hardcoded bayer color format (which is only
used for mt9v032).

Currently the various modes are placed into a table, but when
ov5640_find_mode is called, it has to double check whether
or not the requested framerate is tolerated by the mode.
The determination is based on checking hact, vact, and frame rate.
Only 640x480 is allowed at 60fps and QSXGA is limited to 15fps, but
as the number of permitted frame rates change, this will begin to
add more and more complexity to the check.
This patch simplifies the check by adding the max framerate
allowed for each mode into the table of modes. It then compares
the requested framerate to the max permitted in the mode's table.
This reduces the number of comparisions to one down from three
at run-time.
