Instead the current implementation computes the intersection between the formats it supports and those supported by the first subdev in the stream (typically the image sensor). Remove all the unnecessary logic that supports such algorithm. In order to do this, also change the Tegra210 CSI TPG formats from the current open-coded implementation in vi_tpg_fmts_bitmap_init() to a const array in tegra210.c, just like the one that describes the regular formats.

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.

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: Luca Ceresoli Reviewed-by: Dmitry Osipenko --- Changed in v4: - Added review tags Changed in v3 (suggested by Dmitry Osipenko): - merged the VIP patch and the Tegra20 patch to avoid chicken-egg problem due to the two modules depending on each other at build time - move tegra20_vip_soc to vip.c - remove channel@0 node from device tree parsing - remove unused variable Changed in v2: - fix tegra20_vi_enable() to clear bit when on==false - clamp width/height from set/try_fmt to avoid returning sizeimage=0 (fixes v4l2-compliance) --- drivers/staging/media/tegra-video/Makefile | 2 + drivers/staging/media/tegra-video/tegra20.c | 661 ++++++++++++++++++++ drivers/staging/media/tegra-video/vi.c | 3 + drivers/staging/media/tegra-video/vi.h | 3 + drivers/staging/media/tegra-video/video.c | 5 + drivers/staging/media/tegra-video/video.h | 1 + drivers/staging/media/tegra-video/vip.c | 290 +++++++++ drivers/staging/media/tegra-video/vip.h | 68 ++ 8 files changed, 1033 insertions(+) create mode 100644 drivers/staging/media/tegra-video/tegra20.c create mode 100644 drivers/staging/media/tegra-video/vip.c create mode 100644 drivers/staging/media/tegra-video/vip.h diff --git a/drivers/staging/media/tegra-video/Makefile b/drivers/staging/media/tegra-video/Makefile index dfa2ef8f99ef..6c7552e05109 100644 --- a/drivers/staging/media/tegra-video/Makefile +++ b/drivers/staging/media/tegra-video/Makefile @@ -2,7 +2,9 @@ tegra-video-objs := \ video.o \ vi.o \ + vip.o \ csi.o +tegra-video-$(CONFIG_ARCH_TEGRA_2x_SOC) += tegra20.o tegra-video-$(CONFIG_ARCH_TEGRA_210_SOC) += tegra210.o obj-$(CONFIG_VIDEO_TEGRA) += tegra-video.o diff --git a/drivers/staging/media/tegra-video/tegra20.c b/drivers/staging/media/tegra-video/tegra20.c new file mode 100644 index 000000000000..ac048bbd58f0 --- /dev/null +++ b/drivers/staging/media/tegra-video/tegra20.c @@ -0,0 +1,661 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * Tegra20-specific VI implementation + * + * Copyright (C) 2022 SKIDATA GmbH + * Author: Luca Ceresoli + */ + +/* + * This source file contains Tegra20 supported video formats, + * VI and VIP SoC specific data, operations and registers accessors. + */ + +#include +#include +#include +#include +#include +#include + +#include "vip.h" +#include "vi.h" + +#define TEGRA_VI_SYNCPT_WAIT_TIMEOUT msecs_to_jiffies(200) + +/* This are just good-sense numbers.
