2021-03-22media: dvb-frontends: lgdt3306a.c: remove dead codeDaniel W. S. Almeida
Fix the following coccinelle report: drivers/media/dvb-frontends/lgdt3306a.c:718:5-8: Unneeded variable: "ret". Return "0" on line 744 Code was enclosed with #if 0 and thus this variable was not needed. Remove that function altogether. The lgdt3306a_spectral_inversion function was dropped completely since the function doesn't do anything. A comment was left at its calling site to let others know that spectral_inversion defaults already set for VSB and QAM Found using - Coccinelle (http://coccinelle.lip6.fr) Link: https://lore.kernel.org/linux-media/20200903131311.442255-1-dwlsalmeida@gmail.com Signed-off-by: Daniel W.

2021-03-22media: [next] staging: media: atomisp: fix memory leak of object flashColin Ian King
In the case where the call to lm3554_platform_data_func returns an error there is a memory leak on the error return path of object flash. Fix this by adding an error return path that will free flash and rename labels fail2 to fail3 and fail1 to fail2.

2021-03-22media: dvb_frontend: warn if frontend driver has API issuesMauro Carvalho Chehab
the kAPI for a frontend can use 3 different tuning methods: 1. The hardware tracks internally frequency shifts via its own internal zigzag logic; 2. The hardware has a custom zigzag method, implemented via fe search() ops; 3. The hardware doesn't have any internal zigzag logic. So, the Kernel needs to implement it. Drivers that use the in-kernel software zigzag are required to provide some parameters for the zigzag code to work. Failing to do that will just make the Kernel to tune several times to the very same frequency, delaying the tuning time for no good reason. This is actually a kAPI violation (and an uAPI one, as the frequency shift is exported to the uAPI). Emit a warning on such case, as the driver needs to be fixed.

2021-03-22media: cx25821: switch from 'pci_' to 'dma_' APIChristophe JAILLET
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 'cx25821_riscmem_alloc()' GFP_KERNEL can be used because either this flag is already used in the call chain, or it is called from a 'buf_prepare' function. The call chains are: vb2_ops.buf_prepare (in cx25821-video.c) cx25821_buffer_prepare (in cx25821-video.c) cx25821_risc_buffer cx25821_riscmem_alloc snd_cx25821_hw_params (in cx25821-alsa.c) <-- use GFP_KERNEL cx25821_risc_databuffer_audio cx25821_riscmem_alloc @@ @@ - 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>

The VIDIOC_G/S/TRY_EXT_CTRLS documentation has large explanatory texts for some of the fields in a table. This makes it hard to read. Move those text to a new cell spanning the whole width of the table, similar to what was done for struct v4l2_pix_format. This makes it much more readable. Also move the 'ctrl_class' description to below the 'which' description and just mention that it is deprecated and that 'which' should be used instead. Finally remove 'note::' for the V4L2_CTRL_WHICH_DEF_VAL description. It doesn't have to be marked as a note, it's just a simple paragraph.

2021-03-22media: camss: Add missing format identifiersRobert Foss
The CSI-2 spec defines format identifier for Data Type (DT), and how the Decode Format (DF) & Encode Format (EF) are implemented. The spec does however not define the DF, EF or Plain Format (PF) identifiers, as those are vendor specific. Plain formats describe the size of the pixels written by the RDI units to memory. PLAIN8 for example has the size 8 bits, and PLAIN32 32 bits. The appropriate Plain Format is determined by the Decode Format used. The smallest Plain Format that is able to contain a pixel of the used Decode Format is the appropriate one to use. As the vendor specific identifiers differ between hardware generations, split them out into separate headers.

2021-03-22media: camss: Add support for VFE hardware version Titan 170Robert Foss
Add register definitions for version 170 of the Titan architecture and implement support for the RDI output mode. The RDI mode as opposed to the PIX output mode for the VFE unit does not support any ISP functionality. This means essentially only supporting dumping the output of the whatever the CSI decoder receives from the sensor. For example will a sensor outputting YUV pixel format frames, only allow the VFE to dump those frames as they are received by the ISP to memory through the RDI interface.

In order to support Qualcomm ISP hardware architectures that diverge from older architectures, the VFE subdevice driver needs to be refactored to better abstract the different ISP architectures. Gen1 represents the CAMSS ISP architecture. The ISP architecture developed after CAMSS, Titan, will be referred to as Gen2.

2021-03-22media: camss: Make ISPIF subdevice optionalRobert Foss
This driver supports multiple architecture versions of the Qualcomm ISP. The CAMSS architecure which this driver is name after, and with the introduction of this series, the Titan architecture. The ISPIF is an IP-block that is only present in the CAMSS generation of the architecture. In order to support the Titan generation, make the ISPIF an optional subdevice.

trace_printk() should not be used in production code, since extra memory is used for special buffers whenever trace_puts() is used. Replace it with dev_dbg() which provides all of the desired debugging functionality.
