The build of m32r allmodconfig fails with the error: drivers/media/v4l2-core/videobuf2-dma-contig.c:492:28: error: implicit declaration of function 'dma_get_cache_alignment' The build of videobuf2-dma-contig.c depends on HAS_DMA and it is correctly mentioned in the Kconfig but the symbol VIDEO_TI_CAL also selects VIDEOBUF2_DMA_CONTIG, so it is trying to compile videobuf2-dma-contig.c even though HAS_DMA is not defined.

The Timberdale FPGA video driver has not seen any real development since 2011 (and very little before that). One of the problems with the timblogiw driver is that it uses videobuf instead of the newer vb2 framework. The long term goal is to either convert or remove any driver still using videobuf. Since none of the core v4l developers has the hardware, we cannot convert it ourselves. As far as I can tell it was only used in an Intel demo board in 2009 using Meego: http://www.chinait.com/intelcontent/intelprc/admin/PDFFile/20106411545.pdf which has since been superseded. Moving this driver to staging is the first step towards removal. After 2 or 3 kernel cycles it will be removed altogether unless someone steps up to clean up this driver. Signed-off-by:

It makes sense to make the min_t() cast unsigned here since we don't really want negative sizes. Making it signed causes a static checker warning in Smatch. Smatch knows "fw->size - i" is positive but it doesn't know that fw->size is less than INT_MAX so in theory casting it to int might lead to a negative. Signed-off-by:

The tvp5150 decoder has different input connectors. The actual list of HW inputs depends on the device version but all have at least these 3: 1) Composite0 2) Composite1 3) S-Video and some variants have a 4th possible input connector: 4) Signal generator The driver currently uses the .s_routing callback to switch the input connector but since these are separate HW blocks, it's better to use media entities to represent the input connectors and their source pads linked with the decoder's sink pad. This allows user-space to use the MEDIA_IOC_SETUP_LINK ioctl to choose the input connector. For example using the media-ctl user-space tool: $ media-ctl -r -l '"Composite0":0->"tvp5150 1-005c":0[1]' Signed-off-by:

Not all tvp5150 variants support the same, for example some have an internal signal generator that can output a black screen. So the device id and rom version have to be stored in the driver's state to know what variant is a given device. While being there, remove some redundant comments about the device version since there is already calls to v4l2_info() with that info. Signed-off-by:
