2022-03-18media: platform: place stm32/ and sti/ under st/ dirMauro Carvalho Chehab
As the end goal is to have platform drivers split by vendor, move both stm32/ and sti/ for them to be inside st/ directory. Acked-by: Hugues Fruchet <hugues.fruchet@st.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2020-07-19media: Add V4L2_TYPE_IS_CAPTURE helperEzequiel Garcia
It's all too easy to get confused by the V4L2_TYPE_IS_OUTPUT macro, when it's used as !V4L2_TYPE_IS_OUTPUT. Reduce the risk of confusion with macro to explicitly check for the CAPTURE queue type case. This change does not affect functionality, and it's only intended to make the code more readable.

2020-02-24media: media/platform: rename VFL_TYPE_GRABBER to _VIDEOHans Verkuil
'GRABBER' is a weird name, all other types map to the /dev device names. Rename to 'VIDEO' to be consistent with the other types. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2018-09-11media: use strscpy() instead of strlcpy()Mauro Carvalho Chehab
The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings.

2018-08-02media: headers: fix linux/mod_devicetable.h inclusionsArnd Bergmann
A couple of drivers produced build errors after the mod_devicetable.h header was split out from the platform_device one, e.g. drivers/media/platform/davinci/vpbe_osd.c:42:40: error: array type has incomplete element type 'struct platform_device_id' drivers/media/platform/davinci/vpbe_venc.c:42:40: error: array type has incomplete element type 'struct platform_device_id' This adds the inclusion where needed.

2017-01-31[media] st-hva: add debug file systemJean-Christophe Trotin
This patch creates 4 static debugfs entries to dump: - the device-related information ("st-hva/device") - the list of registered encoders ("st-hva/encoders") - the current values of the hva registers ("st-hva/regs") - the information about the last closed instance ("st-hva/last") It also creates dynamically a debugfs entry for each opened instance, ("st-hva/<instance identifier>") to dump: - the information about the frame (format, resolution) - the information about the stream (format, profile, level, resolution) - the control parameters (bitrate mode, framerate, GOP size...) - the potential (system, encoding...) errors - the performance information about the encoding (HW processing duration, average bitrate, average framerate...) Each time a running instance is closed, its context (including the debug information) is saved to feed, on demand, the last closed instance debugfs entry.

2016-09-09[media] st-hva: add H.264 video encoding supportJean-Christophe Trotin
This patch adds the H.264 video encoding capability in the V4L2 HVA video encoder driver for STMicroelectronics SoC (hva-h264.c).

2016-09-09[media] st-hva: multi-format video encoder V4L2 driverJean-Christophe Trotin
This patch adds V4L2 HVA (Hardware Video Accelerator) video encoder driver for STMicroelectronics SoC. It uses the V4L2 mem2mem framework. This patch only contains the core parts of the driver: - the V4L2 interface with the userland (hva-v4l2.c) - the hardware services (hva-hw.c) - the memory management utilities (hva-mem.c) This patch doesn't include the support of specific codec (e.g. H.264) video encoding: this support is part of subsequent patches.
