Captured video would be out of sync when using the adv7280 with the BT.656-4 protocol. Certain registers (0x04, 0x31, 0xE6) had to be configured properly to ensure BT.656-4 compatibility. An error in the adv7280 reference manual suggested that EAV/SAV mode was enabled by default, however upon inspecting register 0x31, it was determined to be disabled by default.

Captured NTSC video would be out of sync when using the adv7280 with the BT.656-4 protocol. Certain registers (0x04, 0x31, 0xE6) need to be configured properly to ensure BT.656-4 compatibility. Introduce the 'adv,force-bt656-4' property to allow the ADV7280 behavior to be consistent with the ADV7180, where BT.656-4 timing is used by default. Signed-off-by:

Add a hantro_h264_get_ref_nbr() helper function to get the reference picture numbers. This will be used by the Rockchip VDPU2 H.264 driver. This idea was originally proposed by Jonas Karlman in "[RFC 09/12] media: hantro: Refactor G1 H264 code" posted a while ago.

When the VP8 decoders can't find a reference frame, the driver falls back to the current output frame. This will probably produce some undesirable results, leading to frame corruption, but shouldn't cause noisy warnings. Signed-off-by:

In dvb_usb_i2c_init, if i2c_add_adapter fails, it only prints an error message, and then continues to set DVB_USB_STATE_I2C. This affects the logic of dvb_usb_i2c_exit, which leads to that, the deletion of i2c_adap even if the i2c_add_adapter fails. Fix this by returning at the failure of i2c_add_adapter and then move dvb_usb_i2c_exit out of the error handling code of dvb_usb_i2c_init.

Add support for capturing embedded data from the sensor. The only difference with capturing pixel data and embedded data is that we need to ensure the PIX PROC is disabled for embedded data so that CAL doesn't repack the data. Signed-off-by:

CAL RX has a single sink and a single source pad. To support multiple streams, we will have multiple source pads (up to 8, one for each CAL context). Change the driver to allow creating more source pads and change the code accordingly to handle multiple source pads. We still keep CAL_CAMERARX_NUM_SOURCE_PADS as 1, and the behavior is unchanged. Also rename CAL_CAMERARX_PAD_SOURCE to CAL_CAMERARX_PAD_FIRST_SOURCE to highlight that it's the first source. Signed-off-by:

Tomi Valkeinen authored
We don't have any locking in camerarx for the subdev ops. We have managed fine so far without locking, but in the future multiple video capture devices can use the same camerarx, and locking is a must. Add a mutex to protect the camerarx subdev ops. Some of the functions were slightly restructured to make lock handling cleaner. Signed-off-by:

When starting streaming the driver currently programs the buffer address to the CAL base-address register and assigns the buffer pointer to ctx->dma.pending. This is not correct, as the buffer is not "pending", but active, and causes the first buffer to be needlessly written twice. Fix this by assigning the buffer pointer to ctx->dma.active.

Somewhere along the way the context uninitialization has gone a bit odd: * We have cal_ctx_create() but no matching destroy call, but we still need to call cal_ctx_v4l2_cleanup() for each context. * We have cal_media_cleanup() which calls cal_ctx_v4l2_cleanup() for all contexts, but cal_media_init() is not where the contexts are created. * The order of uninit steps in cal_remove() is different than the error handling path in cal_probe(). * cal_probe()'s error handling calls cal_ctx_v4l2_cleanup() for each context, but also calls cal_media_clean(), doing the same context cleanup twice. So fix these, by introducing cal_ctx_destroy(), and using that in appropriate places instead of calling cal_ctx_v4l2_cleanup() in cal_media_clean(). Also use normal kzalloc (and kfree) instead of devm version as we anyway do manual cleanup for each context. Signed-off-by:

Most of the driver has moved from ARRAY_SIZE(cal->phy) to cal->data->num_csi2_phy, but we have one place left in cal_remove. Also, checking for cal->phy[i] != NULL is not needed as we always have all the phys instantiated. Signed-off-by:

The current driver only ever needs 2 DMA contexts (one per PHY), but we need to use more of the 8 contexts to add support for multiple streams. Change the code so that we allocate DMA contexts as needed, which at this time is 1 per PHY, but could be up to 8. Signed-off-by:

struct cal_camerarx has fmtinfo field which is used to point to the current active input format. The only place where the field is used is cal_camerarx_get_ext_link_freq(). With multiple streams the whole concept of single input format is not valid anymore, so lets remove the field by looking up the format in cal_camerarx_get_ext_link_freq(), making it easier to handle the multistream-case in the following patches.

CAL driver enumerates mbus codes in the connected subdev to create a list of supported formats reported to userspace, and initializes ctx->v_fmt and ctx->fmtinfo to one of those formats. This works fine for legacy mode, but is not correct for MC mode, and the list is not even used in MC mode. Fix this by adding a new function, cal_ctx_v4l2_init_mc_format, which only initializes ctx->v_fmt and ctx->fmtinfo to a default value. Signed-off-by:
