PM: runtime: Simplify pm_runtime_get_if_active() usage

2024-02-12T15:57:47Z

There are two ways to opportunistically increment a device's runtime PM usage count, calling either pm_runtime_get_if_active() or pm_runtime_get_if_in_use(). The former has an argument to tell whether to ignore the usage count or not, and the latter simply calls the former with ign_usage_count set to false. The other users that want to ignore the usage_count will have to explicitly set that argument to true which is a bit cumbersome. To make this function more practical to use, remove the ign_usage_count argument from the function. The main implementation is in a static function called pm_runtime_get_conditional() and implementations of pm_runtime_get_if_active() and pm_runtime_get_if_in_use() are moved to runtime.c.

Use V4L2 CCI for accessing device's registers. The 8-bit compatibility read option is removed but this is supported by regmap through other means. Also the CCS register definitions are re-generated with V4L2 CCI definitions. The older SMIA++ register definitions have been manually converted.

Separate CCS static data read-only register access in ccs-reg-access.c by naming them differently. The code in this file generally deals with reading and writing registers where as static data (when it comes to ccs_static_data_read_ro_reg()) contains the read-only register values but no hardware registers are accessed in that case.

media: v4l2-subdev: Rename .init_cfg() operation to .init_state()

2023-12-04T09:37:47Z

The subdev .init_cfg() operation is affected by two issues: - It has long been extended to initialize a whole v4l2_subdev_state instead of just a v4l2_subdev_pad_config, but its name has stuck around. - Despite operating on a whole subdev state and not being directly exposed to the subdev users (either in-kernel or through the userspace API), .init_cfg() is categorized as a subdev pad operation. This participates in making the subdev API confusing for new developers. Fix it by renaming the operation to .init_state(), and make it a subdev internal operation.

media: ccs: Ensure control handlers have been set up after probe

2023-11-22T09:56:34Z

If the sensor remains powered on after probe when it is needed again and the runtime PM usage_count is incremented, the control handler setup for neither control handler is run. As this is, in most cases, a needless operation in probe, track the status of sensor power handling after probe and set up control handlers even if the device was already active right after probe.
