Adds the driver for the LM3560, dual LED Flash The LM3560 has two 1A constant current driver for high current white LEDs. It is controlled via an I2C compatible interface(up to 400kHz). Each flash brightness, torch brightness and enable/disable can be controlled independantly, but flash timeout and operation mode are shared. Signed-off-by:

Antti Palosaari authored
Small changes in order to support tuner version R828D @ 16 MHz clock. There was 'vco_fine_tune' check, which seems to adjust synthesizer output divider (mixer dix / LO div / Rout) by one. R828D seems to return vco_fine_tune=1 every time and that condition causes tuning fail as output divider was increased by one. Resolve problem by skipping whole condition in case of R828D tuner. Just to mention, other tuner, R820T, seems to return 2 here. Synthesizer maximum frequency check was hard coded to check synthesizer N and thus worked correctly only for clock frequencies around 30 MHz. As whole test is quite useless in any case, I removed it totally. Signed-off-by:

The em28xx driver only calls subdevices' .s_power() method to power them down, relying on the hardware to wake up automatically, which is usually the case with tuners. This was acceptable with the old .standby() method, but is wrong with .s_power(). Fixing the driver would be difficult due to a broad supported hardware base. Instead this patch makes use of the unbalanced_power soc-camera subdevice flag to tell the ov2640 driver to balance calls to v4l2_clk_enable() and v4l2_clk_disable() internally. Signed-off-by:
-
Guennadi Liakhovetski authored
Some non soc-camera drivers, e.g. em28xx, use subdevice drivers, originally written for soc-camera, which use soc_camera_power_on() and soc_camera_power_off() helpers to implement their .s_power() methods. Those helpers in turn can enable and disable a clock, if it is supplied to them as a parameter. This works well when camera host drivers balance their calls to subdevices' .s_power() methods. However, some such drivers fail to do that, which leads to unbalanced calls to v4l2_clk_enable() / v4l2_clk_disable(), which then in turn produce kernel warnings. Such behaviour is wrong and should be fixed, however, sometimes it is difficult, because some of those drivers are rather old and use lots of subdevices, which all should be tested after such a fix. To support such drivers this patch adds a work-around, allowing host drivers or platforms to set a flag, in which case soc-camera helpers will only enable the clock, if it is disabled, and disable it only once on the first call to .s_power(0).

To obtain a clock reference consumers supply their device object to the V4L2 clock framework. The latter then uses the consumer device name to find a matching clock. For that to work V4L2 clock providers have to provide the same device name, when registering clocks. This patch adds a helper macro to generate a suitable device name for I2C devices. Signed-off-by:

This struct shall be used by subdevice drivers to pass per-subdevice data, e.g. power supplies, to generic V4L2 methods, at the same time allowing optional host-specific extensions via the host_priv pointer.

If a frame is still decoding when system enters suspend mode, we wait on the device queue for a interrupt condition. This sometimes leads to a timeout because the device queue might not be woken up everytime. Usually, the context queue gets woken up when that context's frame gets decoded. This patch adds a condition to wake up the device queue along with the context queue when the system is in suspend mode. Since the device queue is now woken up, we don't have to check the context's int_cond flag while waiting. Also, we can skip calling try_run after waking up the device queue to ensure that we don't have to wait for more than one frame to be processed. Signed-off-by:

When the current context is running, 1] If release is called, it waits until the job is finished. 2] As soon as the job is finished, v4l2_mem_ctx_release()tries to release the vb2 queues. 3] But if the current context can be scheduled in the v4l2_m2m_job_finish() it schedules the context and tries to call device_run(). 4] As the release() and device_run() sequence can't be predicted sometimes device_run() may get empty vb2 buffers. This patch adds the ABORT state to the job_flags. Once the job_abort() or release() is called on the context, the same context will not be scheduled in the v4l2_m2m_job_finish(). Signed-off-by:

When the current context is running, 1] If release() or streamoff() is called on the current context, it waits until the job is aborted or finished. 2] If the job is finished, driver will call the v4l2_m2m_job_finish(). 3] If the job is aborted inside device_run callback, then driver has to inform the v4l2 mem2mem framework about the same by calling v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR. The current code doesn't call v4l2_m2m_job_finish() in the case, where the job is aborted from the device_run callback. This scenerio is producing a hang as the other queued contexts are not getting scheduled. By adding the ABORT state, driver can understand the current job is aborted and not finished. By checking this flag, driver can call v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR. Signed-off-by:
