This config option is strictly speaking independent of the

Besides, it looks odd when drivers select CEC_CORE and

The CEC framework is used by both drm and media. That makes it tricky
to get the dependencies right.
This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options
out of the media menu and instead drivers that want to use CEC should
select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).

On this driver, it can fall through a switch. I tried to
annotate it, in order to shut up a gcc warning, but that
didn't work, as the logic there is somewhat complex.
So, instead, let's just repeat the code. gcc should likely
optimize it anyway, and this makes the code better readable,

The conversion from soc_camera omitted a correct handling of the clock
gating for a sensor. When the pxa_camera driver module was removed it
tried to unregister clk, but this caused a similar warning:
WARNING: CPU: 0 PID: 6740 at drivers/media/v4l2-core/v4l2-clk.c:278
v4l2_clk_unregister(): Refusing to unregister ref-counted 0-0030 clock!
The clock was at time still refcounted by the sensor driver. Before
the removing of the pxa_camera the clock must be dropped by the sensor
driver. This should be triggered by v4l2_async_notifier_unregister() call
which removes sensor driver module too, calls unbind() function and then
tries to probe sensor driver again. Inside unbind() we can safely
unregister the v4l2 clock as the sensor driver got removed. The original
v4l2_clk_unregister() should be put inside test as the clock can be
already unregistered from unbind(). If there was not any bound sensor
the clock is still present.
The codepath is practically a copy from the old soc_camera. The bug was
tested with a pxa_camera+ov9640 combination during the conversion
of the ov9640 from the soc_camera.

ir_lirc_register() currently creates its own lirc_buffer before
passing the lirc_driver to lirc_register_driver().
When a module is later unloaded, ir_lirc_unregister() gets called
which performs a call to lirc_unregister_driver() and then free():s
the lirc_buffer.
The problem is that:
a) there can still be a userspace app holding an open lirc fd
when lirc_unregister_driver() returns; and
b) the lirc_buffer contains "wait_queue_head_t wait_poll" which
is potentially used as long as any userspace app is still around.
The result is an oops which can be triggered quite easily by a
userspace app monitoring its lirc fd using epoll() and not closing
the fd promptly on device removal.
The minimalistic fix is to let lirc_dev create the lirc_buffer since
lirc_dev will then also free the buffer once it believes it is safe to
do so.

Merge tag 'hwparam-20170420' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull hw lockdown support from David Howells:
"Annotation of module parameters that configure hardware resources
including ioports, iomem addresses, irq lines and dma channels.
This allows a future patch to prohibit the use of such module
parameters to prevent that hardware from being abused to gain access
to the running kernel image as part of locking the kernel down under
UEFI secure boot conditions.
Annotations are made by changing:
module_param(n, t, p)
module_param_named(n, v, t, p)
module_param_array(n, t, m, p)
to:
module_param_hw(n, t, hwtype, p)
module_param_hw_named(n, v, t, hwtype, p)
module_param_hw_array(n, t, hwtype, m, p)
where the module parameter refers to a hardware setting
hwtype specifies the type of the resource being configured. This can
be one of:
ioport Module parameter configures an I/O port
iomem Module parameter configures an I/O mem address
ioport_or_iomem Module parameter could be either (runtime set)
irq Module parameter configures an I/O port
dma Module parameter configures a DMA channel
dma_addr Module parameter configures a DMA buffer address
other Module parameter configures some other value
Note that the hwtype is compile checked, but not currently stored (the
lockdown code probably won't require it). It is, however, there for
future use.
A bonus is that the hwtype can also be used for grepping.
The intention is for the kernel to ignore or reject attempts to set
annotated module parameters if lockdown is enabled. This applies to
options passed on the boot command line, passed to insmod/modprobe or
direct twiddling in /sys/module/ parameter files.
The module initialisation then needs to handle the parameter not being
set, by (1) giving an error, (2) probing for a value or (3) using a
reasonable default.
What I can't do is just reject a module out of hand because it may
take a hardware setting in the module parameters. Some important
modules, some ipmi stuff for instance, both probe for hardware and
allow hardware to be manually specified; if the driver is aborts with
any error, you don't get any ipmi hardware.
Further, trying to do this entirely in the module initialisation code
doesn't protect against sysfs twiddling.
[!] Note that in and of itself, this series of patches should have no
effect on the the size of the kernel or code execution - that is
left to a patch in the next series to effect. It does mark
annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
an already existing field"

killer driver was finally deleted, much to the celebration of the -mm
developers.

show up when you merge to your tree"

When the kernel is running in secure boot mode, we lock down the kernel to
prevent userspace from modifying the running kernel image. Whilst this
includes prohibiting access to things like /dev/mem, it must also prevent
access by means of configuring driver modules in such a way as to cause a
device to access or modify the kernel image.
To this end, annotate module_param* statements that refer to hardware
configuration and indicate for future reference what type of parameter they
specify. The parameter parser in the core sees this information and can
skip such parameters with an error message if the kernel is locked down.
The module initialisation then runs as normal, but just sees whatever the
default values for those parameters is.
Note that we do still need to do the module initialisation because some
drivers have viable defaults set in case parameters aren't specified and
some drivers support automatic configuration (e.g. PNP or PCI) in addition
to manually coded parameters.
This patch annotates drivers in drivers/media/.

Seeing the kunmap_atomic dma_buf_ops share the same name with a macro
in highmem.h, the former can be aliased if any dma-buf user includes
that header.
I'm personally trying to include highmem.h inside scatterlist.h and this
breaks the dma-buf code proper.
Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP.
To maintain consistency I've renamed all four of kmap* and kunmap* to be
map* and unmap*. (Even though only kmap_atomic presently conflicts.)

Enabling vflip currently causes wrong colors.
It seems that (at least with the current sensor setup) REG04_VFLIP_IMG only
changes the vertical readout direction.
Because pixels are arranged RGRG... in odd lines and GBGB... in even lines,
either a one line shift or even/odd line swap is required, too, but
apparently this doesn't happen.
I finally figured out that this can be done manually by setting
REG04_VREF_EN.
Looking at hflip, it turns out that bit REG04_HREF_EN is set there
permanetly, but according to my tests has no effect on the pixel readout
order.
So my conclusion is that the current documentation of sensor register 0x04
is wrong (has changed after preliminary datasheet version 2.2).
I'm pretty sure that automatic vertical line shift/switch can be enabled,
too, but until anyone finds ot how this works, we have to stick with manual
switching.

According to ov2640 software application notes, there are two Automatic
White Balance (AWB) modes, which are selected by DSP register 0xc7:
1) Simple AWB: assumes the average color is gray
+ independent from lens
- doesn't work well if captured area contains unbalanced colors
(e.g. large blue background)
2) Advanced AWB: uses color temperature information
+ more accurate, works with all image contents
- lens specific, requires calibration

warning: (VIDEO_EM28XX_V4L2) selects VIDEO_OV2640 which has unmet direct dependencies (MEDIA_SUPPORT && VIDEO_V4L2 && I2C && GPIOLIB && MEDIA_CAMERA_SUPPORT)
The em28xx driver can use ov2640, but it doesn't depend

So, as we want to allow both usages with and without

The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.
Move those sources to media/cec as well.
The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.
Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).
Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.
CEC drivers should now depend on CEC_CORE.
CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.
The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

With an unknown sensor, norm_maxw() and norm_maxh() return 0 as max.
height and width values, which causes a devide by zero in size_to_scale().
Of course we could use speculative default values for unknown sensors,
but the chance that the device works at this resolution without any
driver/setup is very low and therefore not worth the efforts.
Instead, just don't treat the device as camera.

Use i2c_smbus_read_word_data() instead of i2c_master_send() and
i2c_master_recv() for reading the ID of Micorn sensors.
i2c_smbus_read_word_data() assumes that byes are in little-endian,
so, it uses:
data->word = msgbuf1[0] | (msgbuf1[1] << 8);
However, Micron datasheet describes the ID as if they were read
in big-endian. So, we need to change the byte order in order to
match the ID number as described on their datasheets.

It started with a sporadic message in syslog: "CAM tried to send a
buffer larger than the ecount size" This message is not the fault
itself, but a consecutive fault, after a read error from the CAM. This
happens only on several CAMs, several hardware, and of course sporadic.
It is a consecutive fault, if the last read from the CAM did fail. I
guess this will not happen on all CAMs, but at least it did on mine.
There was a write error to the CAM and during the re-initialization
procedure, the CAM finished the last read, although it got a RS.
The write error to the CAM happened because a race condition between HC
write, checking DA and FR.
This patch added an additional check for DA(RE), just after checking FR.
It is important to read the CAMs status register again, to give the CAM
the necessary time for a proper reaction to HC. Please note the
description within the source code (patch below).

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

N-1 skipping over the pipeline setup section and then start the pipeline
early, if videobuf2 has already enqueued buffers to the driver for
process N but not called the .start_streaming() operation yet
In the case of the video pipelines, this

1) A null-dereference if the pipe->dl is committed at the same time as
the vsp1_video_setup_pipeline() is processing
2) A hardware hang, where a display list is committed without having

It turned out that all versions of MFC v6+ hardware doesn't have a strict
requirement for ALL buffers to be allocated on higher addresses than the
firmware base like it was documented for MFC v5. This requirement is true
only for the device and per-context buffers. All video data buffers can be
allocated anywhere for all MFC v6+ versions. Basing on this fact, the
special DMA configuration based on two reserved memory regions is not
really needed for MFC v6+ devices, because the memory requirements for the
firmware, device and per-context buffers can be fulfilled by the simple
probe-time pre-allocated block allocator introduced in previous patch.
This patch enables support for such pre-allocated block based allocator
always for MFC v6+ devices. Due to the limitations of the memory management
subsystem the largest supported size of the pre-allocated buffer when no
CMA (Contiguous Memory Allocator) is enabled is 4 MiB.
This patch also removes the requirement to provide two reserved memory
regions for MFC v6+ devices in device tree. Now the driver is fully
functional without them.

The main reason for using special configuration of IOMMU domain was the
problem with MFC firmware, which failed to operate properly when placed
at 0 DMA address. Instead of adding custom code for configuring each
variant of IOMMU domain and architecture specific glue code, simply use
what arch code provides and if the DMA base address equals zero, skip
first 128 KiB to keep required alignment. This patch also make the driver
operational on ARM64 architecture, because it no longer depends on ARM
specific DMA-mapping and IOMMU glue code functions.

Current MFC driver depends on the fact that when IOMMU is available, the
DMA-mapping framework and its IOMMU glue will use first-fit allocator.
This was true for ARM architecture, but its not for ARM64 arch. However, in
case of MFC v6+ hardware and latest firmware, it turned out that there is
no strict requirement for ALL buffers to be allocated on higher addresses
than the firmware base. This requirement is true only for the device and
per-context buffers. All video data buffers can be allocated anywhere for
all MFC v6+ versions.
Such relaxed requirements for the memory buffers can be easily fulfilled
by allocating firmware, device and per-context buffers from the probe-time
preallocated larger buffer. This patch adds support for it. This way the
driver finally works fine on ARM64 architecture. The size of the
preallocated buffer is 8 MiB, what is enough for three instances H264
decoders or encoders (other codecs have smaller memory requirements).
If one needs more for particular use case, one can use "mem" module
parameter to force larger (or smaller) buffer (for example by adding
"s5p_mfc.mem=16M" to kernel command line).

Firmware for MFC v6+ variants is not larger than 400 KiB, so there is no
need to allocate a full 1 MiB buffer for it. Reduce it to 512 KiB to keep
proper alignment of allocated buffer.

Once firmware buffer has been converted to use s5p_mfc_priv_buf structure,
it is possible to allocate it with existing s5p_mfc_alloc_priv_buf()
function. This change will help to reduce code variants in the next

To complete DMA memory configuration for MFC device, allocation of the
firmware buffer is needed, because some parameters are dependant on its base
address. Till now, this has been handled in the s5p_mfc_alloc_firmware()
function. This patch moves that logic to s5p_mfc_configure_dma_memory() to
keep DMA memory related operations in a single place. This way
s5p_mfc_alloc_firmware() is simplified and does what it name says. The
other consequence of this change is moving s5p_mfc_alloc_firmware() call
from the s5p_mfc_probe() function to the s5p_mfc_configure_dma_memory().

Interrupt routine must wake process waiting for given interrupt AFTER
updating driver's internal structures and contexts. Doing it in-between
is a serious bug. This patch moves all calls to the wake() function to
the end of the interrupt processing block to avoid potential and real
races, especially on multi-core platforms. This also fixes following issue
reported from clock core (clocks were disabled in interrupt after being
unprepared from the other place in the driver, the stack trace however
points to the different place than s5p_mfc driver because of the race):

The symptom is continuous log "mtk-jpeg 18004000.jpegdec: Context is NULL"
in kernel log. It is because the error handling in irq doesn't clear
interrupt.
The calling flow like as below when issue happen
mtk_jpeg_device_run()
mtk_jpeg_job_abort()
v4l2_m2m_job_finish() -> m2m_dev->curr_ctx = NULL;
mtk_jpeg_dec_irq()
v4l2_m2m_get_curr_priv()
-> m2m_dev->curr_ctx == NULL
-> return NULL
log "Context is NULL"
There is race condition between job_abort() and irq. In order to simplify
code, don't want to add extra flag to maintain state, empty job_abort() and
clear interrupt before v4l2_m2m_get_curr_priv() in irq.

Adjust the keymap to use the correct nec scancodes, and adjust the
rc driver to output the correct nec scancodes.
Now the keymap can be used with any nec receiver, and the rc device
should work with any nec keymap.

update_subrect() adjusts the sub-rectangle to be inside a base area.
It checks width and height to not exceed those of the area, then it
checks the low border (left or top) to lie within the area, then the
high border (right or bottom) to lie there too. This latter check has
a bug, which is fixed by this patch.

After changes to v4l2_clk API introduced in v4.1 by commits a37462b919
'[media] V4L: remove clock name from v4l2_clk API' and 4f528afcfb
'[media] V4L: add CCF support to the v4l2_clk API', ov6650 sensor
stopped responding because v4l2_clk_get(), still called with
depreciated V4L2 clock name "mclk", started to return respective CCF
clock instead of the V4l2 one registered by soc_camera. Fix it by
calling v4l2_clk_get() with NULL clock name.
Created and tested on Amstrad Delta against Linux-4.7-rc3 with
omap1_camera fixes.

The vpif display driver uses a static i2c adapter ID of 1 but on the
da850-evm board in DT boot mode the i2c adapter ID is actually 0.
Make the adapter ID configurable like it already is for vpif capture.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

It's no longer necessary to keep the i2c_client in the device struct
unmodified until a sensor is found, so reduce stack usage in
em28xx_probe_sensor_micron() and em28xx_probe_sensor_omnivision() by using
a pointer to the client instead of a local copy.

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.
