Commit dfb9f94e ("[media] stk1160: Build as a module if SND is m and audio support is selected") had to introduce some complex config dependency handling to compile for all combinations of configs VIDEO_STK1160 and VIDEO_STK1160_AC97. Later, commit e36e6b5f ("[media] stk1160: Remove stk1160-mixer and setup internal AC97 codec automatically") removes the config VIDEO_STK1160_AC97, which renders the previous dependency handling unnecessary. The commit already simplified the dependency of the remaining config VIDEO_STK1160, but it misses the opportunity to merge VIDEO_STK1160 and VIDEO_STK1160_COMMON. So, do that now and simplify the build config definition of the STK1160 USB video capture support. Signed-off-by:

This reverts commit cd61f3c6. That commit's purpose was to prevent the padding from being decoded when userspace didn't set a selection, relying on the default one. However, as described in the Step 6 of the Initialization procedure for the Memory-to-Memory Stateful Video Encoder Interface [1]: "Set the visible resolution for the stream metadata via VIDIOC_S_SELECTION() on the OUTPUT queue if it is desired to be different than the full OUTPUT resolution." And from the Note: "To avoid encoding the padding, the client needs to explicitly configure this selection target" Hence the behavior in the original commit doesn't follow the interface and needs to be reverted. This fixes the following v4l2-compliance failure observed on mt8192-asurada-spherion: fail: v4l2-test-formats.cpp(924): sel.r.width != fmt.g_width() test VIDIOC_S_FMT: FAIL [1] https://www.kernel.org/doc/html/latest/userspace-api/media/v4l/dev-encoder.html#initialization Signed-off-by:

The VI peripheral of Tegra supports capturing from MIPI CSI-2 or parallel video (called VIP in the docs). The staging tegra-video driver currently implements MIPI CSI-2 video capture for Tegra210. Add support for parallel video capture (VIP) on Tegra20. With the generalizations added to the VI driver in previous commits, this is only a matter of adding the vip.c and tegra20.c implementations and registering them. Unfortunately there was no documentation available for the VI or VIP peripherals of Tegra20 (or any other Tegra chips). This implementation has been based entirely on the code from a vendor kernel based on Linux 3.1 and massively adapted to fit into the tegra-video driver. Parts of this code is definitely non-optimal to say the least (especially tegra20_vi_enable() and the single-frame capture logic), but it was impossible to improve it. Signed-off-by:

Tegra20 can do horizontal and vertical image flip, but Tegra210 cannot (either the hardware, or this driver). In preparation to adding Tegra20 support, add a flag in struct tegra_vi_soc so the generic vi.c code knows whether the flip controls should be added or not. Also provide a generic implementation that simply sets two flags in the channel struct. The Tegra20 implementation will enable flipping at stream start based on those flags. Signed-off-by:

Tegra20 supports planar YUV422 capture, which can be implemented by writing U and V base address registers in addition to the "main" base buffer address register. It also supports H and V flip, which among others requires to write the start address (i.e. the 1st offset to write, at the end of the buffer or line) in more registers for Y and, for planar formats, U and V. Add minimal hooks in VI to allow per-SoC optional support to those features: - variables in struct tegra_vi for the U and V buffer base offsets - variables in struct tegra_vi for the Y, U and V buffer start offsets - an optional per-soc VI operation to compute those values on queue setup Signed-off-by:

The CSI module does not handle all the MIPI lane calibration procedure, leaving a small part of it to the VI module. In doing this, tegra_channel_enable_stream() (vi.c) manipulates the private data of the upstream subdev casting it to struct 'tegra_csi_channel', which will be wrong after introducing a VIP (parallel video input) channel. This prevents adding support for the VIP module. It also breaks the logical isolation between modules. Since the lane calibration requirement does not exist in the parallel input module, moving the calibration function to a per-module op is not optimal. Instead move the calibration procedure in the CSI module, together with the rest of the calibration procedures. After this change, tegra_channel_enable_stream() just calls v4l2_subdev_call() to ask for a stream start/stop to the CSI module, which in turn knows all the CSI-specific details to implement it.

tegra_vi_channels_alloc() can primarily fail for two reasons: 1. "ports" node not found 2. port_num > vi->soc->vi_max_channels Case 1 prints nothing, case 2 has a dev_err(). The caller [tegra_vi_init()] has a generic dev_err() on any failure. This mean that in case 2 we print two messages, and in case 1 we only print a generic message. Remove the generic message and add a specific message when case 1 happens, so that we always have one specific message without even increasing the number of dev_dbg*() calls. Signed-off-by:
