af28c99628 media: drivers: Adjust checks for null pointers
The script “checkpatch.pl” pointed information out like the following.

Comparison to NULL could be written !…

Thus fix the affected source code places.

2d3da59ff1 media: drivers: improve a size determination
Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.

1e33936d3b media: cec-gpio: add HDMI CEC GPIO driver
Add a simple HDMI CEC GPIO driver that sits on top of the cec-pin framework.

While I have heard of SoCs that use the GPIO pin for CEC (apparently an
early RockChip SoC used that), the main use-case of this driver is to
function as a debugging tool.

By connecting the CEC line to a GPIO pin on a Raspberry Pi 3 for example
it turns it into a CEC debugger and protocol analyzer.

With 'cec-ctl --monitor-pin' the CEC traffic can be analyzed.

But of course it can also be used with any hardware project where the
HDMI CEC line is hooked up to a pull-up gpio line.

In addition this has (optional) support for tracing HPD changes if the
HPD is connected to a GPIO.

e949f61461 media: s5p-cec: add NACK detection support
The s5p-cec driver returned CEC_TX_STATUS_ERROR for the NACK condition.

Some digging into the datasheet uncovered the S5P_CEC_TX_STAT1 register where
bit 0 indicates if the transmit was nacked or not.

Use this to return the correct CEC_TX_STATUS_NACK status to userspace.

This was the only driver that couldn't tell a NACK from another error, and
that was very unusual. And a potential problem for applications as well.

Tested with my Odroid-U3.

Pull media updates from Mauro Carvalho Chehab:
 "Brazil's Independence Day pull request :-)

  This is one of the biggest media pull requests, with 625 patches
  affecting almost all parts of media (RC, DVB, V4L2, CEC, docs).

  This contains:

   - A lot of new drivers:
     * DVB frontends: mxl5xx, stv0910, stv6111;
     * camera flash: as3645a led driver;
     * HDMI receiver: adv748X;
     * camera sensor: Omnivision 6650 5M driver (ov6650);
     * HDMI CEC: ao-cec meson driver;
     * V4L2: Qualcom camss driver;
     * Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers.

   - The DDbridge DVB driver got a massive update, with makes it in sync
     with modern hardware from that vendor;

   - There's an important milestone on this series: the DVB
     documentation was written in 2003, but only started to be updated
     in 2007. It also used to contain several gaps from the time it was
     kept out of tree, mentioning error codes and device nodes that
     never existed upstream. On this series, it received a massive
     update: all non-deprecated digital TV APIs are now in sync with the
     current implementation;

   - Some DVB APIs that aren't used by any upstream driver got removed;

   - Other parts of the media documentation algo got updated, fixing
     some bugs on its PDF output and making it compatible with Sphinx
     version 1.6.

     As the number of hacks required to build PDF output reduced, I hope
     we'll have less troubles as newer versions of our documentation
     toolchain are released (famous last words);

   - As usual, lots of driver cleanups and improvements"

2436bdcda5 dma-coherent: remove the DMA_MEMORY_MAP and DMA_MEMORY_IO flags
DMA_MEMORY_IO was never used in the tree, so remove it.  That means there is
no need for the DMA_MEMORY_MAP flag either now, so remove it as well and

Use standard V4L2 control to get pixel clock rate from a sensor
linked in the media controller pipeline. Then calculate clock
rates on CSIPHY, CSID and VFE to use the lowest possible.

If the currnet pixel clock rate of the sensor cannot be read then
use the highest possible. This case covers also the CSID test
generator usage.

If VFE is already powered on by another pipeline, check that the
current VFE clock rate is high enough for the new pipeline.
If not return busy error code as VFE clock rate cannot be changed
while VFE is running.

Implements g_/s_selection crop support by using DCMI crop
hardware feature.
User can first get the maximum supported resolution of the sensor
by calling g_selection(V4L2_SEL_TGT_CROP_BOUNDS).
Then user call to s_selection(V4L2_SEL_TGT_CROP) will reset sensor
to its maximum resolution and crop request is saved for later usage
in s_fmt().
Next call to s_fmt() will check if sensor can do frame size request
with crop request. If sensor supports only discrete frame sizes,
the frame size which is larger than user request is selected in
order to be able to match the crop request. Then s_fmt() resolution
user request is adjusted to match crop request resolution.

ab45e85851 media: v4l: vsp1: Allow entities to participate in the partition algorithm
The configuration of the pipeline and entities directly affects the
inputs required to each entity for the partition algorithm. Thus it
makes sense to involve those entities in the decision making process.

Extend the entity ops API to provide an optional .partition() operation.
This allows entities that affect the partition window to adapt the
window based on their configuration.

Entities implementing this operation must update the window parameter in
place, which will then be passed up the pipeline. This creates a process
whereby each entity describes what is required to satisfy the required
output to its predecessor in the pipeline.

787d862091 media: s5p-jpeg: Clear JPEG_CODEC_ON bits in sw reset function
Bits EXYNOS4_DEC_MODE and EXYNOS4_ENC_MODE do not get cleared
on software reset. These bits need to be cleared explicitly.

Even though the bits in question are already cleared in interrupt
service routine, the reset should also clear them in case when
e.g. bootloader uses the codec and leaves it in a bad state.

Clearing the bits turns off the encoder/decoder. If the hardware
is not turned off after use, at subsequent uses it does not work
in a stable manner, resulting in incorrect interrupt status value
being read and e.g. erroneous read of compressed bitstream size.

In case of corrupt images, multiple interrupts may occur
due to different error scenarios.

Since we are removing the src and dest buffers in the first
interrupt itself, crash occurs in the second error interrupts.

Disable the global interrupt before we start processing
the interrupt to avoid the crash.

7ec2c0f72c media: platform: Add Amlogic Meson AO CEC Controller driver
The Amlogic SoC embeds a standalone CEC controller, this patch adds a driver
for such controller.
The controller does not need HPD to be active, and could support up to max
5 logical addresses, but only 1 is handled since the Suspend firmware can
make use of this unique logical address to wake up the device.

The Suspend firmware configuration will be added in an other patchset.

e047c5e0da media: coda: reduce iram size to leave space for suspend to ram
The on-chip SRAM of i.MX6S is only 128 KiB. 4 KiB of that are allocated
for suspend to RAM since commit df595746fa ("ARM: imx: add suspend in
ocram support for i.mx6q"). Reduce the requested IRAM size to 124 KiB to
avoid an allocation failure that causes the coda driver to not use the
SRAM at all.

45340c14e5 media: coda: fix decoder sequence init escape flag
coda_command_sync calls coda_command_async, which writes the
bit_stream_param context variable into the BIT_STREAM_PARAM register,
overwriting the previously set value during coda_start_decoding. Instead
of writing to the register, set bit_stream_param to ensure that the
decoder sequence init command is executed with the escape flag set.

0f59b2d013 media: v4l: omap_vout: vrfb: initialize DMA flags
Passing uninitialized flags into device_prep_interleaved_dma is clearly
a bad idea, and we get a compiler warning for it:

drivers/media/platform/omap/omap_vout_vrfb.c: In function 'omap_vout_prepare_vrfb':
drivers/media/platform/omap/omap_vout_vrfb.c:273:5: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized]

It seems that the OMAP dmaengine ignores the flags, but we should
pick the right ones anyway. This sets the flags I guessed based
on what other drivers used, and Peter confirmed that they are the
right ones.

Commit a53e35db70 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.
