This patch adds driver for CIR controller on MT7622 SoC. It has similar handling logic as the previously MT7623 does, but there are some differences in the register and field definition. So for ease portability and maintenance, those differences all are being kept inside the platform data as other drivers usually do. Currently testing successfully on NEC and SONY remote controller.

This patch is the preparation patch in order to adapt into various hardware through adding platform data which holds specific characteristics and differences among MediaTek supported CIR devices instead of the old way defining those data in the static way as macro has. And the existing logic would be slightly changed to operate on those data which the actual device depends on. Signed-off-by:

The NEC decoder and the Sanyo decoders check if dev->keypressed is true before calling rc_repeat (without holding dev->keylock). Meanwhile, the XMP and JVC decoders do no such checks. This patch makes sure all users of rc_repeat() do so consistently by removing extra checks in NEC/Sanyo and modifying the check a bit in rc_repeat() so that no input event is generated if the key isn't pressed.

The configuration of the pipeline and entities directly affects the inputs required to each entity for the partition algorithm. Thus it makes sense to involve those entities in the decision making process. Extend the entity ops API to provide an optional .partition() operation. This allows entities that affect the partition window to adapt the window based on their configuration. Entities implementing this operation must update the window parameter in place, which will then be passed up the pipeline. This creates a process whereby each entity describes what is required to satisfy the required output to its predecessor in the pipeline. Signed-off-by:

Provide register definitions required for UDS phase and partition algorithm support. The registers and bits defined here are available on Gen3 hardware only. Signed-off-by:

Kieran Bingham authored
As we develop the partition algorithm, we need to store more information per partition to describe the phase and other parameters. To keep this data together, further abstract the existing v4l2_rect into a partition specific structure. As partitions only have horizontal coordinates, store the left and width values only. When generating the partition windows, operate directly on the partition struct rather than copying and duplicating the processed data Signed-off-by:

The vsp1_pipe object context variables for div_size and current_partition allowed state to be maintained through processing the partitions during processing. Now that the partition tables are calculated during stream on, there is no requirement to store these variables in the pipe object. Utilise local variables for the processing as required.

Kieran Bingham authored
Previously the active window and partition sizes for each partition were calculated for each partition every frame. This data is constant and only needs to be calculated once at the start of the stream. Extend the vsp1_pipe object to dynamically store the number of partitions required and pre-calculate the partition sizes into this table. Signed-off-by:

Separate the code change from the function move so that code changes can be clearly identified. This commit has no functional change. The partition algorithm functions will be changed, and vsp1_video_pipeline_setup_partitions() will call vsp1_video_partition(). To prepare for that, move the function without any code change.

Presently any received buffers are only released back to vb2 if vsp1_video_stop_streaming() is called. If vsp1_video_start_streaming() encounters an error, we will be warned by the vb2 handlers that buffers have not been returned. Move the buffer cleanup code to its own function to prevent duplication and call from both vsp1_video_stop_streaming() and the error path in vsp1_video_start_streaming(). Signed-off-by:

Previously, vblank range given to user was too big, falling outside of permissible range for a given resolution. Sometimes, too low vblank resulted in errors. Now, limit vblank to only permissible range for a given resolution. This change limits lower-bounds of vblank, doesn't affect upper bounds. Signed-off-by:

The v4l2_subdev_ops structure is only passed as the third argument of v4l2_i2c_subdev_init, which is const, so the v4l2_subdev_ops structure can be const as well. The other structures are only stored in the v4l2_subdev_ops structure, all the fields of which are const, so these structures can also be const. Done with the help of Coccinelle. Signed-off-by:

Previously, pixel-rate/(pixels-per-line * lines-per-frame) was yielding incorrect frame timing for the user. OV sensor is using internal timing and this requires conversion (internal timing -> PPL) for correct HBLANK calculation. Now, change pixels-per-line domain from internal sensor clock to pixels domain. Set HBLANK read-only because fixed PPL is used for all resolutions. And, use more accurate link-frequency 422.4MHz instead of rounding down to 420MHz. Signed-off-by:

struct v4l2_subdev.host_priv is intended to be used by another driver. This is hardly good design but back in the days of platform data was a quick hack to get things done. As the sub-device specific bus information can be stored to the ISP driver specific struct allocated along with v4l2_async_subdev, keep the information there and only there. Signed-off-by:

The CSI PHY is associated with a CSI receiver. The code assumes this receiver is a CSI2 module and relies on the CSI2 module object heavily to access the ISP or pipeline objects. However, the receiver could also be a CSI1/CCP2 module. Pass a new CSI receiver entity pointer to the CSI PHY acquire function, and replace all hardcoded usage of the CSI2 module with that CSI receiver entity. Signed-off-by:

The CEC_EVENT_PIN_LOW/HIGH defines and the cec_queue_pin_event() function did not specify that these were about CEC pin events. Since in the future there will also be HPD pin events it is wise to rename the event defines and function to CEC_EVENT_PIN_CEC_LOW/HIGH and cec_queue_pin_cec_event() now before these become part of the ABI.
