Define a new vendor property in the maxim,max9286 binding schema. The new property allows to declare that the remote camera power-over-coax is controlled by one of the MAX9286 gpio lines. As it is currently not possible to establish a regulator as consumer of the MAX9286 gpio controller for this purpose, the property allows to declare that the camera power is controlled by the MAX9286 directly. The property accepts a gpio-index (0 or 1) and one line polarity flag as defined by dt-bindings/gpio/gpio.h. Reviewed-by:

This IR receiver has two limitations: 1) Any IR pulse or space longer than 12ms will be truncated to 12ms 2) Any pulses/spaces after the first 68 are lost ir_raw_event_reset() won't help here. If the IR cannot be decoded, any decoder should reset itself, and if it does not, this is a bug in the decoder.

The ir receiver generates an interrupt with the IR data, once a space of at least ok_count is has been seen. Currently this is about 110ms; when holding down a button on a nec remote, no such space is seen until the button is released. This means nothing happens until you release the button. The sample rate is fixed at 46us, so the maximum space that can be encoded is about 12ms. So, the set ok_count above that at 23ms.

When a driver reports a timeout, no more IR activity will be reported until the next pulse. A space is inserted between the timeout and the next pulse, based on ktime. The timeout reports already a duration, so this duration should not be added to the gap. Otherwise there is no change to the functionality. Signed-off-by:

There are only two lines in mtk_vcodec_release_enc_pm, using pm_runtime_disable and put_device instead directly. Move pm_runtime_enable outside mtk_vcodec_release_enc_pm to symmetry with pm_runtime_disable, after that, rename mtk_vcodec_init_enc_pm to *_clk since it only has clock operations now. Signed-off-by:

Use the dma_set_mask_and_coherent helper to set vdec DMA bit mask to support 34bits iova space(16GB) that the mt8192 iommu HW support. Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G, regarding which iova range VDEC actually locate, it depends on the dma-ranges property of vdec dtsi node. Signed-off-by:

Marking a picture as long-term reference is valid for DPB but not for RPS. Change flag name to match with the description in HEVC spec chapter "8.3.2 Decoding process for reference picture set". PocStCurrBefore, PocStCurrAfter, PocLtCurr lists could be built by the kernel from the DPB entries struct v4l2_hevc_dpb_entry, using the information in the rps field. This way RPS flags becomes useless and are removed. This patch breaks the staging HEVC API because it introduces a new flag, changes a field name in v4l2_hevc_dpb_entry structure and removes V4L2_HEVC_DPB_ENTRY_RPS_* flags.

The bytesperline field of the pixfmt should be only for the first plane in case of planar formats like YUV420 or YUV422. The bytesperline is used by the driver to compute the framesize. We have to report a different bpp (bytes per pixel) to v4l2 in bytesperline than the actual bpp. For example for YUV420, the real bpp is 12, but the first plane has only 8 bpp. Thus we report a bytesperline 8*width instead of 12*width. However, for real framezise we have to compute 12*width*height. Hence added a new variable to hold this information and to correctly compute the frame size. Signed-off-by:

The ISC supports a full broad range of frame sizes. Until now, the subdevice was queried for possible frame sizes and these were reported to the user space. However, the ISC should not care about which frame sizes the subdev supports, as long as this frame size is supported. Thus, report a continuous range from smallest frame size up to the max resolution. Signed-off-by:
