2020-12-03media: ccs: Replace somewhat harsh internal checks based on BUG with WARN_ONSakari Ailus1-4/+5
If an internal driver error was encountered, BUG was issued. Instead, do less harsh WARN_ON_ONCE and try to manage with the consequences. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-12-03media: ccs: The functions to get compose or crop rectangle never return NULLSakari Ailus1-6/+2
The NULL check is not needed as the functions do not return NULL. Remove the check (and BUG). Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-12-03media: ccs: Stop reading arrays after the first zeroSakari Ailus1-0/+3
The register arrays have a certain size but not all the entries will be relevant. In practice reading can be stopped after encountering a zero value in the array. Do that to avoid extra reads.

2020-12-03media: ccs: Combine revision number major and minor into oneSakari Ailus3-14/+16
The module revision number major and minor are both 8 bits while the sensor revision number is 16 bits. Combine the module revision into one number. This also adds printing the lowest 8 bits of the module version through the sysfs attribute.

2020-12-03media: ccs: Add CCS static data parser librarySakari Ailus4-1/+1403
Add a parser library for parsing the CCS static data format. The library may be also compiled in user space as the format has uses also in the user space. Therefore it is dual licensed under the 3-clause BSD license as well. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-12-03media: ccs: Fix obtaining bus information from firmwareSakari Ailus1-7/+6
Let v4l2_fwnode_endpoint_alloc_parse to figure out the type of the data bus. As the old bindings did not require the "bus-type" property, we need to rely on guessing between CSI-2 D-PHY and CCP2. Setting the type to CSI-2 D-PHY will parse just that and succeed even if no data-lanes are set. Also add a comment on the matter to the driver to avoid breaking this in the future.

2020-12-03media: saa7146: switch from 'pci_' to 'dma_' APIChristophe JAILLET3-24/+28
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'saa7146_pgtable_alloc()' GFP_KERNEL can be used because the callers are either .buf_prepare functions or function that already use GFP_KERNEL (hidden in a 'vmalloc_32()' call). When memory is allocated in 'saa7146_init_one()' GFP_KERNEL can be used because it is probe function and no lock is taken in the between. When memory is allocated in 'saa7146_vv_init()' GFP_KERNEL can be used because this function already uses GFP_KERNEL and no lock is taken in the between. When memory is allocated in 'vbi_workaround()' GFP_KERNEL can be used because it is only called from a .open function. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

On AMD Family 15h (Models 30h-3fh), I/O Memory Management Unit RiSC engine sometimes stalls, requiring a reset. As result, MythTV and w-scan won't scan channels on the AMD Kaveri APU with the Hauppauge QuadHD TV tuner card. For the solution I added the Input/Output Memory Management Unit's PCI Identity of 0x1423 to the broken_dev_id[] array, which is used by a quirks logic meant to fix similar problems with other AMD chipsets.

2020-12-02media: i2c: imx219: Selection compliance fixesHans Verkuil1-8/+9
To comply with the intended usage of the V4L2 selection target when used to retrieve a sensor image properties, adjust the rectangles returned by the imx219 driver. The top/left crop coordinates of the TGT_CROP rectangle were set to (0, 0) instead of (8, 8) which is the offset from the larger physical pixel array rectangle. This was also a mismatch with the default values crop rectangle value, so this is corrected. Found with v4l2-compliance. While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and CROP_BOUNDS have the same size as the non-active pixels are not readable using the selection API. Found with v4l2-compliance.

The subdev's video device node was only assigned after registering the device node in the system. While it is unlikely that a driver needed to use this field in handling system calls to its file handle, there remains a slim chance the devnode field remains NULL while the driver expects to find a video node there. Assign the devnode field before registering the device, and assign it back to NULL if the registration failed.
