[media] v4l2-ctrls: add RX RDS controls

2014-07-25T22:27:51+00:00

The radio-miropcm20 driver has firmware that decodes the RDS signals. So in that
case the RDS data becomes available in the form of controls.

Add support for these controls to the control framework, allowing the miro driver
to use them.

[media] v4l2-ctrls: add new RDS TX controls

2014-07-25T22:26:14+00:00

The si4713 supports several RDS features not yet implemented in the driver.

This patch adds the missing RDS functionality to the list of RDS controls.

The ALT_FREQS control is a compound control containing an array of up
to 25 (the maximum according to the RDS standard) frequencies. To support
that the V4L2_CTRL_TYPE_U32 was added.

[media] v4l2-ctrls/v4l2-controls.h: add MD controls

2014-07-17T14:57:27+00:00

Add the 'Detect' control class and the new motion detection controls.
Those controls will be used by the solo6x10 and go7007 drivers.

[media] v4l: add control for RF tuner PLL lock flag

2014-03-13T13:26:49+00:00

Add volatile boolean control to indicate if tuner frequency synthesizer
is locked to requested frequency. That means tuner is able to receive
given frequency. Control is named as "PLL lock", since frequency
synthesizers are based of phase-locked-loop. Maybe more general name
could be wise still?

[media] v4l: reorganize RF tuner control ID numbers

2014-03-13T13:26:44+00:00

It appears that controls are ordered by ID number when enumerating.
That could lead illogical UI as controls are usually enumerated and
drawn by the application at runtime.

Change order of controls by reorganizing assigned IDs now as we can.
It is not reasonable possible after the API is released. Also, leave
some spare space between IDs too for possible future extensions.

[media] v4l: add RF tuner channel bandwidth control

2014-03-13T13:26:43+00:00

Modern silicon RF tuners has one or more adjustable filters on
signal path, in order to filter noise from desired radio channel.

Add channel bandwidth control to tell the driver which is radio
channel width we want receive. Filters could be then adjusted by
the driver or hardware, using RF frequency and channel bandwidth
as a base of filter calculations.

On automatic mode (normal mode), bandwidth is calculated from sampling
rate or tuning info got from userspace. That new control gives
possibility to set manual mode and let user have more control for
filters.

[media] v4l2-controls.h: Add addtional Flash fault bits

2014-03-11T12:57:48+00:00

Three Flash fault are added. V4L2_FLASH_FAULT_UNDER_VOLTAGE for the case low
voltage below the min. limit. V4L2_FLASH_FAULT_INPUT_VOLTAGE for the case
falling input voltage and chip adjust flash current not occur under voltage
event. V4L2_FLASH_FAULT_LED_OVER_TEMPERATURE for the case the temperature
exceed the maximun limit

[media] v4l: add RF tuner gain controls

2014-03-05T18:46:56+00:00

Modern silicon RF tuners used nowadays has many controllable gain
stages on signal path. Usually, but not always, there is at least
3 gain stages. Also on some cases there could be multiple gain
stages within the ones specified here. However, I think that having
these three controllable gain stages offers enough fine-tuning for
real use cases.

1) LNA gain. That is first gain just after antenna input.
2) Mixer gain. It is located quite middle of the signal path, where
RF signal is down-converted to IF/BB.
3) IF gain. That is last gain in order to adjust output signal level
to optimal level for receiving party (usually demodulator ADC).

Each gain stage could be set rather often both manual or automatic
(AGC) mode. Due to that add separate controls for controlling
operation mode.
