-
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:
