2019-08-26media: imx: add csc/scaler mem2mem devicePhilipp Zabel
Add a single imx-media mem2mem video device that uses the IPU IC PP (image converter post processing) task for scaling and colorspace conversion. On i.MX6Q/DL SoCs with two IPUs currently only the first IPU is used. The hardware only supports writing to destination buffers up to 1024x1024 pixels in a single pass, arbitrary sizes can be achieved by rendering multiple tiles per frame.

2019-08-19media: hantro: Move copy_metadata() before doing a decode operationBoris Brezillon
Some decoders use intra slice/frame references. The capture buffer pointed by these references might be new and thus have invalid timestamp which prevents the decoder logic from retrieving the vb2_buffer object based on the output buf timestamp. Copy all metadata (including the timestamp) before starting the decode operation.

2019-08-15media: imx: mipi csi-2: Don't fail if initial state times-outEzequiel Garcia
Not all sensors will be able to guarantee a proper initial state. This may be either because the driver is not properly written, or (probably unlikely) because the hardware won't support it. While the right solution in the former case is to fix the sensor driver, the real world not always allows right solutions, due to lack of available documentation and support on these sensors. Let's relax this requirement, and allow the driver to support stream start, even if the sensor initial sequence wasn't the expected. Also improve the warning message to better explain the problem and provide a hint that the sensor driver needs to be fixed.

2019-07-25media: staging: davinci: remove vpfe driverArnd Bergmann
The davinci_vpfe driver was merged into staging back in 2012 by Manjunath Hadli from TI, with a long TODO list. For all I can tell, since then it has only seen fixes for compile-time issues and global cleanups, but nobody has actually worked on the items on the TODO list. To make things worse, the driver in its current form is incompatible with the platform code in arch/arm/mach-davinci, i.e. the driver expects to get its platform_data passed to the device as a 'struct vpfe_config', but uses a differnet definition for that structure compared to what the platform uses. Finally, there is another driver for the same device in drivers/media/platform/davinci/vpfe_capture.c. From all I can tell, the staging version was originally a copy of a more featureful driver in TI's downstream kernels. However, that kernel no longer supports dm365 after linux-2.6.37, and the mainline version moved in a different direction.

Conversion to use gpio descriptors broke all gpio lookups as devm_gpiod_get_index was converted to use dev->driver->name for the gpio name lookup. Fix this by using the name param. In addition gpiod_get post-fixes the -gpios to the name so that shouldn't be included in the call. However this then breaks the of_find_property call to see if the gpio entry exists as all fbtft treats all gpios as optional. So use devm_gpiod_get_index_optional instead which achieves the same thing and is simpler. Nishad confirmed the changes where only ever compile tested.

2019-07-12scripts/spelling.txt: drop "sepc" from the misspelling listPaul Walmsley
The RISC-V architecture has a register named the "Supervisor Exception Program Counter", or "sepc". This abbreviation triggers checkpatch.pl's misspelling detector, resulting in noise in the checkpatch output. The risk that this noise could cause more useful warnings to be missed seems to outweigh the harm of an occasional misspelling of "spec". Thus drop the "sepc" entry from the misspelling list. [akpm@linux-foundation.org: fix existing "sepc" instances, per Joe] Link: http://lkml.kernel.org/r/20190518210037.13674-1-paul.walmsley@sifive.com Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com> Cc: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
