Hans Verkuil 8aab72bb07 [media] si4713: si4713_set_rds_radio_text overwrites terminating \0
si4713_set_rds_radio_text will overwrite the terminating zero at the
end of the rds radio text string in order to send out a carriage return
as per the RDS spec.
Use a separate char buffer for the CR instead of corrupting the control
string.

Dinesh Ram cc6d618fdf [media] si4713: move supply list to si4713_platform_data
The supply list is needed by the platform driver, but not by the usb driver.
So this information belongs to the platform data and should not be hardcoded
in the subdevice driver.

Dinesh Ram adc2325923 [media] si4713: HID blacklist Si4713 USB development board
The Si4713 development board contains a Si4713 FM transmitter chip
and is handled by the radio-usb-si4713 driver.
The board reports itself as (10c4:8244) Cygnal Integrated Products, Inc.
and misidentifies itself as a HID device in its USB interface descriptor.
This patch ignores this device as an HID device and hence loads the custom driver.

In the si4713_tx_tune_power() method, the args array element 'power'
can take values between SI4713_MIN_POWER and SI4713_MAX_POWER. power = 0
is also valid. All the values (0 > power < SI4713_MIN_POWER) are illegal
and hence are all mapped to SI4713_MIN_POWER.

Sylwester Nawrocki f8e2ff2621 [media] omap3isp: Modify clocks registration to avoid circular references
The clock core code is going to be modified so clk_get() takes
reference on the clock provider module. Until the potential circular
reference issue is properly addressed, we pass NULL as the first
argument to clk_register(), in order to disallow sub-devices taking
a reference on the ISP module back trough clk_get(). This should
prevent locking the modules in memory.

of the format description entry is expressed in bits then
the bytesperline value needs to be divided, not multiplied,
by that value to get the number of bytes required to store
single line of image samples.

Laurent Pinchart 112da08512 [media] v4l: omap4iss: Cancel streaming when a fatal error occurs
When a fatal error that prevents any further video streaming occurs in a
pipeline, all queued buffers must be marked as erroneous and new buffers
must be prevented from being queued. Implement this behaviour with a new
omap4iss_pipeline_cancel_stream() function that can be used by
submodules to cancel streaming.

Laurent Pinchart 216814fb01 [media] v4l: omap4iss: csi2: Replace manual if statement with a subclk field
Instead of manually checking whether the CSI2 module is CSI2a or CSI2b
in order to select the right subclock to enable/disable, add a subclk
field to the iss_csi2 structure, initialize it with the corresponding
subclock value and use it at runtime.

Laurent Pinchart f3632ba850 [media] v4l: omap4iss: Reset the ISS when the pipeline can't be stopped
When a failure to stop a module in the pipeline is detected, the only
way to recover is to reset the ISS. However, as other users can be using
a different pipeline with other modules, the ISS can't be reset
synchronously with the error detection.
Keep track of modules that have failed to stop, and reset the ISS
accordingly when the last user releases the last reference to the ISS.
Refuse to start streaming on a pipeline that contains a crashed module,
as the hardware wouldn't work anyway.
Modify the omap4iss_pipeline_set_stream() function to record the new ISS
pipeline state only when no error occurs, except when stopping the
pipeline in which case the pipeline is still marked as stopped.

Laurent Pinchart af15d025ec [media] v4l: omap4iss: Enable/disabling the ISP interrupts globally
ISP interrupts are enabled/disabled when starting/stopping the IPIPEIF
or resizer. This doesn't permit using the two modules in separate
pipelines. Fix it by enabling/disabling the ISP interrupts at the same
time as the ISS interrupts, in the ISS device get/put operations.

Return an error from the s_stream handlers when stopping the stream
failed instead of just logging the error and ignoring it. While we're
at it, move the logging code from submodules to the driver code.

instead of the pixel format currently returned. Move the media bus
format to pixel format conversion to the existing caller.
