Mauro Carvalho Chehab b2cd27448b [media] media-device: map new functions into old types for legacy API
The legacy media controller userspace API exposes entity types that
carry both type and function information. The new API replaces the type
with a function. It preserves backward compatibility by defining legacy
functions for the existing types and using them in drivers.

This works fine, as long as newer entity functions won't be added.

Unfortunately, some tools, like media-ctl with --print-dot argument
rely on the now legacy MEDIA_ENT_T_V4L2_SUBDEV and MEDIA_ENT_T_DEVNODE
numeric ranges to identify what entities will be shown.

Also, if the entity doesn't match those ranges, it will ignore the
major/minor information on devnodes, and won't be getting the devnode
name via udev or sysfs.

As we're now adding devices outside the old range, the legacy ioctl
needs to map the new entity functions into a type at the old range,
or otherwise we'll have a regression.

Detected on all released media-ctl versions (e. g. versions <= 1.10).

Fix this by deriving the type from the function to emulate the legacy
API if the function isn't in the legacy functions range.

Luis R. Rodriguez f6e45661f9 dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc()
Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs. Keep the
old names for compatibility for a while, these can be removed
at a later time. A guard is left to enable backporting of the
rename, and later remove of the old mapping defines seemlessly.

Build tested successfully with allmodconfig.

The following Coccinelle SmPL patch was used for this simple
transformation:

@ rename_dma_alloc_writecombine @
expression dev, size, dma_addr, gfp;
@@

-dma_alloc_writecombine(dev, size, dma_addr, gfp)
+dma_alloc_wc(dev, size, dma_addr, gfp)

@ rename_dma_free_writecombine @
expression dev, size, cpu_addr, dma_addr;
@@

-dma_free_writecombine(dev, size, cpu_addr, dma_addr)
+dma_free_wc(dev, size, cpu_addr, dma_addr)

@ rename_dma_mmap_writecombine @
expression dev, vma, cpu_addr, dma_addr, size;
@@

-dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
+dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)

We also keep the old names as compatibility helpers, and
guard against their definition to make backporting easier.

The driver verifies that the type of the remote entity matches its
expectations when setting up fimc-lite links and returns an error if it
doesn't. Those checks can never fail as the links are created by the
driver in a way that always match its expectations (the SINK and
SOURCE_ISP pads are connected to subdevs only and the SOURCE_DMA pad is
connected to a video node only). Remove them.

Matthieu Rogez 0899f62ff9 [media] em28xx: fix Terratec Grabby AC97 codec detection
EMP202 chip inside Terratec Grabby (hw rev 2) seems to require some time
before accessing reliably its registers. Otherwise it returns some values
previously put on the I2C bus.

To account for that period, we delay card setup until we have a proof that
accessing AC97 registers is reliable. We get this proof by polling
AC97_RESET until the expected value is read. We also check that unrelated
registers don't return the same value. This second check handles the case
where the expected value is constantly returned no matter which register
is accessed.

This makes it easier to handle in userspace and allows to

Changing to a text format and values in microseconds also
makes the userspace interface independent of the setting of
SAMPLE_PERIOD in the driver.

Sakari Ailus 76413791a0 [media] v4l: Add generic pipeline power management code
When the Media controller framework was merged, it was decided not to add
pipeline power management code for it was not seen generic. As a result, a
number of drivers have copied the same piece of code, with same bugfixes
done to them at different points of time (or not at all).

Add these functions to V4L2. Their use is optional for drivers.

Shuah Khan 050b6c98b4 [media] media: au0828 enable the right media source when input changes
Change vidioc_s_input() to enable the media source for the newly
selected input.

v4l2-core enables source before calling au0828's vidioc_s_input()
handler. Hence, when input selection changes, media source for the
newly selected input needs to be enabled.

Shuah Khan 174ced212c [media] media: au0828 set ctrl_input in au0828_s_input()
dev->ctrl_input is set in vidioc_s_input() and doesn't get set in
au0828_s_input(). As a result, dev->ctrl_input is left uninitialized
until user space calls s_input.

It works correctly because the default input value is 0 and which is
what dev->ctrl_input gets initialized via kzalloc().

Change to set dev->ctrl_input in au0828_s_input(). Also optimize
vidioc_s_input() to return if the new input value is same as the
current.

Heiner Kallweit 449c1fcd86 [media] media: rc: nuvoton: support reading / writing wakeup sequence via sysfs
This patch adds a binary attribute /sys/class/rc/rc?/wakeup_data which
allows to read / write the wakeup sequence.

In combination with the core extension for exposing the most recent raw
packet this allows to easily define and set a wakeup sequence.

At least on my Zotac CI321 the BIOS resets the wakeup sequence at each boot
to a factory default. Therefore I use a udev rule
SUBSYSTEM=="rc", DRIVERS=="nuvoton-cir", ACTION=="add", RUN+="<script>"
with the script basically doing
cat <stored wakeup sequence> >/sys${DEVPATH}/wakeup_data
