To let userspace propagate formats downstream in a media controller
scenario, the video source pad (now pad 1, DEMOD_PAD_VID_OUT) must allow
setting and getting the format. Incidentally, tvp5150_fill_fmt was
implemented for this pad, not for the new analog input pad (now pad 0,
DEMOD_PAD_IF_INPUT).
Fixes: 55606310e77f ("[media] tvp5150: create the expected number of pads")

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 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.

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.

Even if bus is not hot-pluggable, devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on

While testing with CONFIG_UBSAN, I got this warning:
drivers/media/i2c/tc358743.c: In function 'tc358743_probe':
drivers/media/i2c/tc358743.c:1930:1: error: the frame size of 2480 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
The problem is that the i2c_rd8/wr8/rd16/... functions in this driver pass
a pointer to a local variable into a common function, and each call to one
of them adds another variable plus redzone to the stack.
I also noticed that the way this is done is broken on big-endian machines,
as we copy the registers in CPU byte order.
To address both those problems, I'm adding two helper functions for reading
a register of up to 32 bits with correct endianess and change all other
functions to use that instead. Just to be sure we don't get the problem
back with changed optimizations in gcc, I'm also marking the new functions
as 'noinline', although my tests with gcc-7 don't require that.

Originally Toshiba told us that the only way to disable HDCP was to
set the receiver in repeater mode, that would make the authentication
fail because of missing software support. It has worked fine with all
the sources we and our customers has used, until it was reported
problems with Apple MacBook (Retina, 12-inch, Early 2015)
(https://support.apple.com/kb/SP712?locale=en_US&viewlocale=en_US)
with Apple A1612 USB type-C multiport adapter
(http://www.apple.com/shop/product/MJ1K2AM/A/usb-c-digital-av-multiport-adapter)
Finally Toshiba came up with a hidden bit that is named "Manual HDCP
authentication". In this patch the original "repeater mode" concept is
removed, and the new bit is set instead.
With his patch HDCP is disabled when connected to the Apple MacBook
and all other sources we have tested so far. The Apple MacBook is
constantly trying to authenticate, but fails and continues to transmit
unencrypted video.

The number of CSI lanes that should be used is set to the CSI_CONTROL
register by indirectly writing to the CSI_CONFW register. When the
number of lanes is read back from the CSI_CONTROL register the value
is usually correct, but we have seen that it suddenly is 1 for a short
moment before the correct value is restored again.
Toshiba have not figured out why that happen, but we have found it
safer to store the value in the driver.

The adv7604 driver platform data contains fields for configuring the drive
strength of the output pins. When probing the driver through DT these
fields are not explicitly initialized, which means they are left at 0. This
is a reserved setting for the drive strength configuration though and can
cause signal integrity issues.
Whether these signal integrity issues are visible depends on the PCB
specifics (e.g. the higher the load capacitance for the output the more
visible the issue). But it has been observed on existing solutions at high
pixel clock rates.
Initialize the drive strength settings to the power-on-reset value of the
device when probing through devicetree to avoid this issue.

If 'ov9640_reg_read()' does not return 0, then 'val' is left unmodified.
As it is not initialized either, the return value can be anything.
It is likely that returning the error code was expected here.

The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.
This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.
Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

the CRC32 helper is not there:
drivers/media/built-in.o: In function `s5k4ecgx_s_power':

This adds the 'select' that all other users of this function have.

The s_stream() handler incorrectly writes the whole MISC_CTL register to
enable or disable the outputs, overriding the output pinmuxing
configuration. Fix it to only touch the output enable bits.
The CONF_SHARED_PIN register is also written by the same function,
resulting in muxing the INTREQ signal instead of the VBLK/GPCL signal on
the INTREQ/GPCL/VBLK pin. As the driver doesn't support interrupts this
is obviously incorrect, and breaks operation on other devices. Fix it by
removing the write.

The FID/GLCO/VLK/HVLK and INTREQ/GPCL/VBLK pins are muxed differently
depending on whether the input is an S-Video or composite signal. The
comment that explains the logic doesn't reflect the code. It appears
that the comment is incorrect, as disabling the output data bus in
composite mode makes no sense. Update the comment to match the code.
While at it define macros for the MISC_CTL register bits, the code is
too confusing with numerical values.

The tvp5150 doesn't support format setting through the subdev pad API
and thus implements the set format handler as a get format operation.
The single handler, tvp5150_fill_fmt(), resets the device by calling
tvp5150_reset(). This causes malfunction as the device can be reset at
will, possibly from userspace when the subdev userspace API is enabled.
The reset call was added in commit ec2c4f3f93cb ("[media] media:
tvp5150: Add mbus_fmt callbacks"), probably as an attempt to set the
device to a known state before detecting the current TV standard.
However, the get format handler doesn't access the hardware to get the
TV standard since commit 963ddc63e20d ("[media] media: tvp5150: Add
cropping support"). There is thus no need to reset the device when
getting the format.
However, removing the tvp5150_reset() from the get/set format handlers
results in the function not being called at all if the bridge driver
doesn't use the .reset() operation. The operation is nowadays abused and
shouldn't be used, so shouldn't expect bridge drivers to call it. To
make sure the device is properly initialize, move the reset call from
the format handlers to the probe function.
