get_user_pages() may return -errno, such as -EFAULT. So don't blindly use
its return value as an offset into dma->map[] for the next get_user_pages()
call. Since we'll give up and return an error if either fails, don't even
make the second call if the first failed to give us exactly what we were
looking for.
The old code would also call put_page() on as many elements of dma->map[]
as we'd asked for, regardless of how many were valid.
[Andy Walls modified this patch to return -EFAULT instead of -EINVAL
as Paul's observation "I'm not sure -EINVAL is the best return code vs
-EFAULT or -ENOMEM, [...]" was correct. The return value bubbles up
as a return code for write(), for which the V4L2 API spec indicates
EINVAL is incorrect and EFAULT is correct.]

This patch in fourcc_to_ipu_pix, eliminate also the pixel formats mappings
that, first are not used within mainline code and second, standing at
the datasheets, they will not work properly:
The IPU internal bus support only the following data formatting
(44.1.1.3 Data Flows and Formats):
1 YUV 4:4:4 or RGB-8 bits per color component
2 YUV 4:4:4 or RGB-10 bits per color component
3 Generic data (from sensor to the system memory only)
And format conversions are done:
- from memory: unpacking from other formats to IPU supported ones
- to memory: packing in the inverse order.
So, assigning a packing/unpacking strategy to the IPU for those formats
will produce a packing to memory and not the inverse.

v4l2-ctl and qv4l2 enumerate controls using V4L2_CTRL_FLAG_NEXT_CTRL,
falling back to the old method if the flag isn't supported.
The v4l2_subdev_queryctrl function will currently handle that flag, but
for the controls of the subdev only. This isn't right, it should refuse
this flag, otherwise v4l2-ctl will only see the controls of the first
subdev.

Having the device detection happening at reset is bad, as every time,
it will produce a message like:

This only polutes the log and for an accidental kernel hacker, it looks

Remove the now obsolete set_freq. Also merge set_addr and set_type_addr.
In the past, it used to have two different setup calls, one to set just
the tuner type to any tuner found, and another to set the type only if
the address matches. Those two internal calls were grouped together,
but the functions weren't merged, making the code uglier.

Power down tuners at suspend. At resume, if the tuner is in standby,
calls set_mode, that will turn it on and set the latest frequencies.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
In the past, T_STANDBY were used on devices with a separate radio tuner to
mark a tuner that were disabled. With the time, it got newer meanings.
Also, due to a bug at the logic, the driver might incorrectly return
T_STANDBY to userspace.
So, instead of keeping the abuse, just use a boolean for storing
such information.
We can't remove T_STANDBY yet, as this is used on two other drivers. A
latter patch will address its usage outside tuner-core.

Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
This is a big patch with no functional changes. It just
rearranges everything inside the driver, and prepares to
break TV and Radio into two separate fops groups.
Currently, it has an heuristics logic to determine if the
call came from radio or video. However, the caller driver
knows for sure, so tuner-core shouldn't try to guess it.

Instead of per-model tests all over the code, use some parameters
at the board entries to describe the model variants for:
- devices with 417 MPEG encoder;
- devices that use external AV;
- devices where vbi VANC endpoint doesn't work;
- devices with xc5000 that require different IF
initialization (and probably will cover also
xc3028).
- devices with xceive tuner that require a reset
during init.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
The check for xc5000 assumes that the tuner will always
be using the same bus and will have the same address.
As those are configurable via dev->board, it should use,
instead, the values defined there.
Also, a similar type of test will be needed by other
tuners (for example, for TUNER_XC2028)

When a device is not detected, the driver prints a warning message.
That's ok, except for the fact that, even on newer devices that have
eeprom but aren't yet supported, it prints a message saying that the

Fix it by having a separate message for devices with eeprom, but not

The STV0900 features two demodulator paths in one chip. Thus it is not
possible to use the generic power off function of the chip when sending
one of them to standby. The other path will stop working in that case.
The sleep function now switches off functionality specific to the demod
path. The global stuff is only switched off, when both paths are in
sleep mode. The wakeup function always turns on the global functionality
and then works specific to the path.
