* media: staging: media: omap4iss: Remove unused macro functionAline Santana Cordeiro2021-05-101-3/+0
| | | | | | | | Remove unused macro function "v4l2_dev_to_iss_device(dev)". Signed-off-by: Aline Santana Cordeiro <alinesantanacordeiro@gmail.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
* media: staging: media: omap4iss: Added SPDX license identifiersDaniel Graefe2018-09-121-5/+1
| | | | | | | | | | | | | | | | Added missing SPDX license identifiers to all files of the omap4iss driver. Most files already have license texts which clearly state them to be licensed under GPL 2.0 or later. SPDX identifiers were added accordingly. Some files do not have any license text. SPDX identifiers for GPL 2.0 were added to them, in accordance with the default license of the kernel.

| | | | | | | | The media graph walk requires initialisation and cleanup soon. Update the users to perform the soon necessary API calls. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] staging: v4l: omap4iss: Use media entity enumeration interfaceSakari Ailus2016-01-111-2/+2
| | | | | | | | Instead of using a bitmap directly in a driver, use the new media entity enumeration interface to perform the same. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] include/media: move platform_data to linux/platform_data/mediaMauro Carvalho Chehab2015-11-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's not mix platform_data headers with the core headers. Instead, let's create a subdir at linux/platform_data and move the headers to that common place, adding it to MAINTAINERS. The headers were moved with: mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/ And the references fixed with this script: MAIN_DIR="linux/platform_data/" PREV_DIR="media/" DIRS="media/" echo "Checking affected files" >&2 for i in $DIRS; do for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do n=`basename $j` git grep -l $n done done|sort|uniq >files && ( echo "Handling files..." >&2; echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>
* [media] v4l: omap4iss: Replace outdated OMAP4 control pad API with sysconLaurent Pinchart2015-04-281-0/+4
| | | | | | | | | | | | | | | | | | | | The omap4_ctrl_pad_readl and omap4_ctrl_pad_writel functions have been removed by commit efde234674d9 but are still used by the OMAP4 ISS driver, resulting in a compilation breakage: drivers/staging/media/omap4iss/iss_csiphy.c: In function 'omap4iss_csiphy_config': drivers/staging/media/omap4iss/iss_csiphy.c:167:2: error: implicit declaration of function 'omap4_ctrl_pad_writel' [-Werror=implicit-function-declaration] omap4_ctrl_pad_writel(cam_rx_ctrl, Fix the problem by using the syscon API to reaplace the control pad API. Lookup the syscon instance by compatible name for now as the OMAP4 ISS driver doesn't support DT yet.

* [media] staging: omap4iss: Fix type of struct iss_device::crashedRasmus Villemoes2014-07-261-1/+1
| | | | | | | | | | | The crashed member of struct iss_device is documented to be a bitmask, but a bool doesn't hold that many (usable) bits. Lines 589 and 659 of iss.c strongly suggest that "unsigned int" was meant (the same type as struct iss_pipeline::entities). Currently, any crashed entity will be blamed on index 0, which is unlikely to be what was intended.

* [media] omap4iss: Use a common macro for all sleep-based poll loopsLaurent Pinchart2014-05-231-0/+14
| | | | | | | | | Instead of implementing usleep_range-based poll loops manually (and slightly differently), create a generic iss_poll_wait_timeout() macro and use it through the driver.

* [media] v4l: omap4iss: Cancel streaming when a fatal error occursLaurent Pinchart2013-12-111-0/+1
| | | | | | | | | | | When a fatal error that prevents any further video streaming occurs in a pipeline, all queued buffers must be marked as erroneous and new buffers must be prevented from being queued. Implement this behaviour with a new omap4iss_pipeline_cancel_stream() function that can be used by submodules to cancel streaming.

* [media] v4l: omap4iss: Reset the ISS when the pipeline can't be stoppedLaurent Pinchart2013-12-111-0/+5
| | | | | | | | | | | | | | | | | When a failure to stop a module in the pipeline is detected, the only way to recover is to reset the ISS. However, as other users can be using a different pipeline with other modules, the ISS can't be reset synchronously with the error detection. Keep track of modules that have failed to stop, and reset the ISS accordingly when the last user releases the last reference to the ISS. Refuse to start streaming on a pipeline that contains a crashed module, as the hardware wouldn't work anyway. Modify the omap4iss_pipeline_set_stream() function to record the new ISS pipeline state only when no error occurs, except when stopping the pipeline in which case the pipeline is still marked as stopped.

* [media] v4l: omap4iss: Enable/disabling the ISP interrupts globallyLaurent Pinchart2013-12-111-3/+0
| | | | | | | | | | ISP interrupts are enabled/disabled when starting/stopping the IPIPEIF or resizer. This doesn't permit using the two modules in separate pipelines. Fix it by enabling/disabling the ISP interrupts at the same time as the ISS interrupts, in the ISS device get/put operations.

* [media] v4l: omap4iss: Add support for OMAP4 camera interface - CoreSergio Aguirre2013-12-031-0/+153
This adds a very simplistic driver to utilize the CSI2A interface inside the ISS subsystem in OMAP4, and dump the data to memory. Check Documentation/video4linux/omap4_camera.txt for details. This commit adds the driver core, registers definitions and documentation.
