media: smiapp: Put the device again if starting streaming fails

2020-01-03T15:38:06+00:00

If there was an error in starting streaming, put the runtime usage count of the device. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: smiapp: Avoid maintaining power state information

2020-01-03T15:37:39+00:00

Instead of keeping track of the power state ourselves, let runtime PM handle it. This also splits handling controls between side effect management and writing the new configuration to the sensor's registers. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: smiapp: unlock on error in smiapp_start_streaming()

2019-11-05T11:20:22+00:00

We added two new error paths to smiapp_start_streaming(), but we can't return directly without dropping the "sensor->mutex" lock.

media: smiapp: Rename update_mode as pll_blanking_update

2019-10-24T21:56:37+00:00

Rename the confusingly named smiapp_update_mode() function as smiapp_pll_blanking_update(). The function is used to calculate new PLL and blanking configuration after binning or scaling configuration has been changed. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: smiapp: Register sensor after enabling runtime PM on the device

2019-10-24T21:56:18+00:00

Earlier it was possible that the parts of the driver that assumed runtime PM was enabled were being called before runtime PM was enabled in the driver's probe function. So enable runtime PM before registering the sub-device. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: smiapp: Use non-binned and binned limits correctly

2019-10-24T21:55:59+00:00

Use non-binned limits when binning is disabled and binned when they're enabled. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: smiapp: Don't update sensor configuration during power-on init

2019-10-24T21:55:39+00:00

The sensor configuration since it was previously powered off was not changed, so no need to update the PLL configuration etc. What is necessary though is to re-apply the configuration to the sensor's registers. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: smiapp: Move binning configuration to streaming start

2019-10-24T21:55:18+00:00

Only write the binning configuration at stream start. It has no effect otherwise. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: smiapp: Don't get binning limits dynamically

2019-10-24T21:54:57+00:00

The driver implementation assumed the binning limits could change dynamically based on the binning configuration. This is not actually the case; these limits are static and suitable to be used with all binning configurations but possibly not optimal limit for many of those configurations.

media: smiapp: Destroy sensor's mutex

2019-10-24T21:54:30+00:00

Destroy the mutex initialised by the driver in probe. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
