media: vsp1: Fix LIF buffer thresholds

2018-12-03T19:57:30Z

Commit de2bc45c84f7 ("media: vsp1: Update LIF buffer thresholds") updated the LIF buffer thresholds based on the VSP version, but used the wrong model mask. This resulted in all VSP instances to be treated as a Gen3 VSPD, breaking operation on all Gen2 platforms as well as on H3 ES2.0, M3-N, V3M and V3H. Fix it.

media: vsp1: Document max_width restriction on UDS

2018-09-17T18:54:20Z

The UDS is currently restricted based on a partition size of 256 pixels. Document the actual restrictions, but don't increase the implementation. The extended partition algorithm may later choose to utilise a larger partition size to support overlapping partitions which will improve the quality of the output images.

media: vsp1: Document max_width restriction on SRU

2018-09-17T18:54:03Z

The SRU is currently restricted to 256 pixels as part of the current partition algorithm. Document that the actual capability of this component is 288 pixels, but don't increase the implementation. The extended partition algorithm may later choose to utilise a larger input to support overlapping partitions which will improve the quality of the output images.

media: vsp1: use periods at the end of comment sentences

2018-09-17T18:53:28Z

The style of this driver uses periods at the end of sentences in comments, but it is applied inconsitently. Update a selection of comments which were discovered to be missing their period. Also fix the spelling of one usage of 'instantiate' Signed-off-by: Kieran Bingham Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: vsp1: Remove artificial minimum width/height limitation

2018-09-17T18:52:49Z

The VSP1 has a minimum width and height of a single pixel, with the exception of pixel formats with sub-sampling. Remove the artificial minimum width and minimum height limitation, and instead clamp the minimum dimensions based upon the sub-sampling parameter of that dimension.

media: vsp1: Fix YCbCr planar formats pitch calculation

2018-09-17T18:51:43Z

YCbCr planar formats can have different pitch values for the luma and chroma planes. This isn't taken into account in the driver. Fix it. Based on a BSP patch from Koji Matsuoka .

media: vsp1: Update LIF buffer thresholds

2018-09-17T18:51:10Z

The LIF module has a data buffer to accommodate clock rate differences between the DU and the VSP. Several programmable threshold values control DU start of frame notification by the VSP and VSP clock stop/resume. The R-Car Gen2 and Gen3 datasheets recommend values for the different SoCs. Update the driver to use the recommended values for optimal operation. Based on a BSP patch from Koji Matsuoka , with Gen2 and V3H/V3M updates.

media: vsp1: Fix vsp1_regs.h license header

2018-09-17T18:49:57Z

All source files of the vsp1 driver are licensed under the GPLv2+ except for vsp1_regs.h which is licensed under GPLv2. This is caused by a bad copy&paste that dates back from the initial version of the driver. Fix it.

media: use strscpy() instead of strlcpy()

2018-09-11T17:32:17Z

The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings. Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Kees Cook Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
