When dvb_create_media_graph fails, the debugfs kept inside client should be released. However, the current implementation does not release them. Fix this by adding a new goto label to call smsdvb_debugfs_release. Fixes: 0d3ab841 ("[media] dvb core: must check dvb_create_media_graph()") Signed-off-by:

The SDM630/660 SoCs (and variants) have another clock source for the PHY, which must be set to a rate that's equal or greater than the CSI PHY timer clock: failing to do this will produce PHY overflows when trying to get a stream from a very high bandwidth camera sensor and outputting no frame or a partial one. Since I haven't found any usecase in which the csiX_phy clock needs to be higher than the csiXphy_timer, let's just set the same rate on both, which seems to work just perfect. Signed-off-by:

Add support for the Qualcomm SDM630/636/660 and SDA variants' camera subsystem. These SoCs are equipped with: - 3x CSI PHY 3-Phase v1.0 (downstream csiphy-v3.5) - 4x CSID v5.0 - 2x ISPIF v3.0 - 2x VFE 4.8 As a note, this camera subsystem is very similar to the one that is found in the MSM8998/APQ8098 SoCs.

Add the support for VFE 4.8 in the camss-vfe-4-7 driver, as this one really is a minor revision, requiring the very same management and basically having the same register layout as VFE 4.7, but needing a different QoS and DS configuration, using a different register to enable the wm and habing the same UB size for both instances (instead of a different size between instance 0 and 1).

In preparation to add support for VFE 4.8, rename these functions by adding the vfe version that they are referred to (for example, vfe_get_ub_size -> vfe47_get_ub_size), as these are the only ones that will be different for the VFE version 4.8. Signed-off-by:

Resetting the ISPIF VFE0 context is wrong if we are using the VFE1 for dual-camera or simply because a secondary camera is connected to it: in this case the reset will always happen on the VFE0 ctx of the ISPIF, which is .. useless. Fix this usecase by adding the ISPIF_RST_CMD_1 address and choose where to do the (or what to) reset based on the VFE line id. Signed-off-by:

This allows the timeout to be set with the LIRC_SET_REC_TIMEOUT ioctl. The timeout was hardcoded at just over 20ms, but returned 120ms when queried with the LIRC_GET_REC_TIMEOUT ioctl. This also ensures the idle threshold is set correctly with a base clock other than 8Mhz. Acked-by:

If a user holds a button down on a remote, then no ir idle interrupt will be generated until the user releases the button, depending on how quickly the remote repeats. No IR is processed until that point, which means that holding down a button may not do anything. This also resolves an issue on a Cubieboard 1 where the IR receiver is picking up ambient infrared as IR and spews out endless "rc rc0: IR event FIFO is full!" messages unless you choose to live in the dark.

Add support of BT656 embedded synchronization bus. This mode allows to save hardware synchro lines hsync & vsync by replacing them with synchro codes embedded in data stream. This bus type is only compatible with 8 bits width data bus. Due to reserved values 0x00 & 0xff used for synchro codes, valid data vary from 0x1 to 0xfe, this is up to sensor to clip accordingly pixel data. As a consequence of this clipping, JPEG is not supported with this bus type. DCMI crop feature is also not available with this bus type. Signed-off-by:

Add support of BT656 embedded synchronization bus mode in DCMI driver. Add "bus-type" property and make it required so that there is no ambiguity between parallel mode (bus-type=5) and BT656 mode (bus-type=6). BT656 mode allows to save hardware synchro lines hsync & vsync by replacing them with synchro codes embedded in data stream, hence hsync-active & vsync-active properties are useless in this mode. With DCMI, BT656 bus mode is only compatible with 8 bits width data bus. Signed-off-by:

cx231xx_close_extension and hence cx231xx_audio_fini() are called with the cx231xx device lock held, but snd_cx231xx_pcm_close() also grabs that mutex when closing the file on behalf of arecord. There seems to be no reason to wait for sound card resources to be released, so let the release be asynchronous. Tested with a Hauppauge 955Q (2040:b123) and Linux 5.9.6; the hang described in the bug no longer occurs and disconnecting the device correctly terminates arecord with ENODEV.

The dma engine should be stopped first. The driver waits for an interrupt to stop the stream in a known state after a frame. If rkisp1_cap_stream_disable() is called after stopping the rest of the pipeline, then most likely the interrupt won't arrive, we'll get a timeout and debugfs variables mp_stop_timeout or sp_stop_timeout will be incremented.
