Change the start of the MCI ID range (internally used only) to 48 and define an ID for the SX8 card type. Use this new ID to handle device attachment. This change is done in preparation for support of more MCI based cards. Picked up from the upstream dddvb GIT. Signed-off-by:

Throughout the function, dev->link[l] is used several times. Unclutter this a bit by declaring a ddb_link var at the top of the function, assign the address of dev->link[l] to it and use that var to access the link[] struct member. Picked up from the upstream dddvb GIT. Signed-off-by:

ddbridge has a few MDIO related remainders (defines, hwinfo struct) which aren't of any use for the in-kernel driver at all (they're only used in conjunction with the OctoNet SAT>IP boxes which the kernel driver doesn't have any support for), so clean this up. Signed-off-by:

In demod_attach_stv0910(), the LNBH25 IC is being blindly attached and, if the result is bad, blindly attached on another possible I2C address. The LNBH25 uses it's set_voltage function to test for the IC and will print an error to the kernel log on failure. Prevent this by probing the possible I2C address and use this (and only this) to attach the LNBH25 I2C driver. This also allows the stv0910 attach function to be a bit cleaner. Picked up from the upstream dddvb GIT and adapted for the LNBH25 driver variant from the kernel tree. Signed-off-by:

The em28xx driver never touched the EM2874 register bits that control the transport stream packet filters, leaving them at whatever default the firmware has set. E.g. the Pinnacle 290e disables them by default, while the Hauppauge WinTV dualHD enables discarding NULL packets by default. However, some applications require NULL packets, e.g. to determine the load in DOCSIS segments, so discarding NULL packets is undesired for such applications. This patch simply extends the bit mask when starting or stopping the transport stream packet capture, so that the filter bits are cleared. It has been verified that this makes the Hauppauge WinTV dualHD pass an unfiltered DVB-C stream including NULL packets, which it didn't before. Signed-off-by:

Friio device contains "gl861" bridge and "tc90522" demod, for which the separate drivers are already in the kernel. But friio driver was monolithic and did not use them, practically copying those features. This patch decomposes friio driver into sub drivers and re-uses existing ones, thus reduces some code. It adds some features to gl861, to support the friio-specific init/config of the devices and implement i2c communications to the tuner via demod with USB vendor requests.

Look up of buffers in s5p_mfc_handle_frame_new, s5p_mfc_handle_frame_copy_time functions is not working properly for DMA addresses above 2 GiB. As a result flags and timestamp of returned buffers are not set correctly and it breaks operation of GStreamer/OMX plugins which rely on the CAPTURE buffer queue flags. Due to improper return type of the get_dec_y_adr, get_dspl_y_adr callbacks and sign bit extension these callbacks return incorrect address values, e.g. 0xfffffffffefc0000 instead of 0x00000000fefc0000. Then the statement: "if (vb2_dma_contig_plane_dma_addr(&dst_buf->b->vb2_buf, 0) == dec_y_addr)" is always false, which breaks looking up capture queue buffers. To ensure proper matching by address u32 type is used for the DMA addresses. This should work on all related SoCs, since the MFC DMA address width is not larger than 32-bit. Changes done in this patch are minimal as there is a larger patch series pending refactoring the whole driver. Signed-off-by:

Commit 34dbb848 ("media: mem2mem: Remove excessive try_run call") removed a redundant call to v4l2_m2m_try_run but instead introduced a bug. Consider the following case: 1) Context A schedules, queues and runs job A. 2) While the m2m device is running, context B schedules and queues job B. Job B cannot run, because it has to wait for job A. 3) Job A completes, calls v4l2_m2m_job_finish, and tries to queue a job for context A, but since the context is empty it won't do anything. In this scenario, queued job B will never run. Fix this by calling v4l2_m2m_try_run from v4l2_m2m_try_schedule. While here, add more documentation to these functions.

Currently this driver does not support cropping. The supported modes are the following, all capturing the entire area: - 3840x2160, 1:1 binning (native sensor resolution) - 1920x1080, 2:1 binning - 1280x720, 3:1 binning The VIDIOC_SUBDEV_S_FMT ioctl chooses among these 3 configurations the one that matches the requested format. Add cropping support via VIDIOC_SUBDEV_S_SELECTION: with target V4L2_SEL_TGT_CROP to choose the captured area, with V4L2_SEL_TGT_COMPOSE to choose the output resolution. To maintain backward compatibility we also allow setting the compose format via VIDIOC_SUBDEV_S_FMT. To obtain this, compose rect and output format are computed in the common helper function __imx274_change_compose(), which sets both to the same width/height values. Cropping also calls __imx274_change_compose() whenever cropping rect size changes in order to reset the compose rect (and output format size) for 1:1 binning. Also rename enum imx274_mode to imx274_binning (and its values from IMX274_MODE_BINNING_* to IMX274_BINNING_*). Without cropping, the two naming are equivalent. With cropping, the resolution could be different, e.g. using 2:1 binning mode to crop 1200x960 and output a 600x480 format. Using binning in the names avoids any misunderstanding. For the same reason, replace the 'size' field in struct imx274_frmfmt with 'bin_ratio'. [Sakari Ailus: Remove leftover condition in imx274_apply_trimming] Signed-off-by:

Currently 2-bytes and 3-bytes registers are set by very similar functions doing the needed shift & mask manipulation, followed by very similar for loops setting one byte at a time over I2C. Replace all of this code by a unique helper function that calls regmap_bulk_write(), which has two advantages: - sets all the bytes in a unique I2C transaction - removes lots of now unused code.

This patch adds V4L2 sub-device driver for OV2680 image sensor. The OV2680 is a 1/5" CMOS color sensor from Omnivision. Supports output format: 10-bit Raw RGB. The OV2680 has a single lane MIPI interface. The driver exposes following V4L2 controls: - auto/manual exposure, - exposure, - auto/manual gain, - gain, - horizontal/vertical flip, - test pattern menu. Supported resolution are only: QUXGA, 720P, UXGA. [Sakari Ailus: Drop "-level" from Kconfig help text] Signed-off-by:

The ADV7180 and ADV7182 transmit whole fields, bottom field followed by top (or vice-versa, depending on detected video standard). So for chips that do not have support for explicitly setting the field mode via I2P, set the field mode to V4L2_FIELD_ALTERNATE. I2P converts fields into frames using an edge adaptive algorithm. The frame rate is the same as the 'field rate': e.g. X fields per second are now X frames per second. Signed-off-by:
