Andrew-CT Chen authored
The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs. It is able to handle video decoding/encoding of in a range of formats. The driver provides with VPU firmware download, memory management and the communication interface between CPU and VPU. For VPU initialization, it will create virtual memory for CPU access and IOMMU address for vcodec hw device access. When a decode/encode instance opens a device node, vpu driver will download vpu firmware to the device. A decode/encode instant will decode/encode a frame using VPU interface to interrupt vpu to handle decoding/encoding jobs. Signed-off-by:

The formats are interleaved with the YUV packed and miscellaneous formats, making the result confusing especially with the YUV444 format being packed and not planar like YUV410 or YUV420. Move them to their own group as the 2 planes or 3 non-contiguous planes formats to clarify the header. Signed-off-by:

Add detection of source pad number for drivers aware of the media controller API, so that rcar-vin can create device nodes to support modern drivers such as adv7604.c (for HDMI on Lager) and the converted adv7180.c (for composite) underneath. Building rcar_vin gains a dependency on CONFIG_MEDIA_CONTROLLER, in line with requirements for building the drivers associated with it. Signed-off-by:

The dv_timings_cap() and enum_dv_timings() pad operations take a pad number as an input argument and return the DV timings capabilities and list of supported DV timings for that pad. Commit bd3e275f ("[media] media: i2c: adv7604: Use v4l2-dv-timings helpers") broke this as it started ignoring the pad number, always returning the information associated with the currently selected input. Fix it. Fixes: bd3e275f ("[media] media: i2c: adv7604: Use v4l2-dv-timings helpers") Signed-off-by:

The power_on function of the driver resets the chip and sets the CHIP_CONTROL register to 0. This switches the operating mode to slave. The s_stream function sets the correct mode. But this caused problems on a board where the camera chip is operated as master. The camera started after a random amount of time streaming an image, I observed between 10 and 300 seconds. The STRFM_OUT and STLN_OUT pins are not connected on this board which may cause some issues in slave mode. I could not find any documentation about this. Keeping the chip in master mode after the reset helped to fix this issue for me. Signed-off-by:

Since commit b4226107 ("regmap: i2c: fallback to SMBus if the adapter does not support standard I2C"), regmap-i2c will check the I2C_FUNC_SMBUS_[BYTE|WORD]_DATA functionality based on the regmap_config setting if the adapter does not support standard I2C. So remove the I2C_FUNC_SMBUS_WORD_DATA functionality check in the driver code. Signed-off-by:

Audio hw params are shared across all DMA channels, so if the user changes any of these while any DMA channel is enabled, it will impact the enabled channels, potentially causing serious instability issues. This commit avoids such situation, by preventing any hw param change (on any DMA channel) if any other DMA audio channel is capturing. Signed-off-by:

Currently, the driver has a fixed period size of 4096 bytes (2048 frames). Since this hardware can configure the audio capture size, this commit allows a period size range of [512-4096]. This is very useful to reduce the audio latency. Signed-off-by:

Now that we've introduced the dma_mode parameter to pick the DMA operation, let's use it to also select the audio DMA operation. When dma_mode != memcpy, the driver will avoid using memcpy in the audio capture path, and the DMA hardware operation will act directly on the ALSA buffers. Signed-off-by:

Now that the driver has the infrastructure to support more DMA modes, let's add the DMA scatter-gather mode. In this mode, the device delivers sequential top-bottom frames. The scatter-gather logic is based on staging's tw686x-kh driver (by Krzysztof Ha?asa). Tested-by:

Now that the driver has the infrastructure to support more DMA modes, let's add the DMA contiguous interlaced frame mode. In this mode, the DMA P and B buffers are programmed with the user-provided buffers. When a P (or B) frame is ready, a new buffer is dequeued into P (or B). In addition to interlaced fields, the device can also be programmed to deliver alternate fields. Only interlaced mode is supported for now. Tested-by:

Let's set the corner stone to support all the DMA modes available on this device. For stability reasons, the driver is currently setting DMA frame mode, and using single DMA buffers to get the P and B buffers. Each frame is then memcpy'ed into the user buffer. However, other platforms might be interested in avoiding this memcpy, or in taking advantage of the chip's DMA scatter-gather capabilities. To achieve this, this commit introduces a "dma_mode" module parameter, and a tw686x_dma_ops struct. This will allow to define functions to alloc/free DMA buffers, and to return the frames to userspace. The memcpy-based method described above is named as dma_mode="memcpy". Current alloc/free functions are renamed as tw686x_memcpy_xxx, and are now used through a memcpy_dma_ops. Tested-by:

Those structs are used only at bdisp-hw, so they shouldn't be there in a header file that it is used elsewhere.
