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, GFP_KERNEL can be used because in all cases, it is called from a probe function and no lock is taken in the between. The call chain is: ngene_probe (probe function, used in ngene-cards.c) --> ngene_get_buffers --> AllocCommonBuffers (call dma_alloc_coherent) --> create_ring_buffer (call dma_alloc_coherent) --> AllocateRingBuffers (call dma_alloc_coherent) @@ @@ - 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:

Video engine uses eclk and vclk for its clock sources and its reset control is coupled with eclk so the current clock enabling sequence works like below. Enable eclk De-assert Video Engine reset 10ms delay Enable vclk It introduces improper reset on the Video Engine hardware and eventually the hardware generates unexpected DMA memory transfers that can corrupt memory region in random and sporadic patterns. This issue is observed very rarely on some specific AST2500 SoCs but it causes a critical kernel panic with making a various shape of signature so it's extremely hard to debug. Moreover, the issue is observed even when the video engine is not actively used because udevd turns on the video engine hardware for a short time to make a query in every boot. To fix this issue, this commit changes the clock handling logic to make the reset de-assertion triggered after enabling both eclk and vclk. Also, it adds clk_unprepare call for a case when probe fails. clk: ast2600: fix reset settings for eclk and vclk Video engine reset setting should be coupled with eclk to match it with the setting for previous Aspeed SoCs which is defined in clk-aspeed.c since all Aspeed SoCs are sharing a single video engine driver. Also, reset bit 6 is defined as 'Video Engine' reset in datasheet so it should be de-asserted when eclk is enabled. This commit fixes the setting.

When setting the source media bus code in the resizer, we first check that the current media bus code in the source is yuv encoded format. This is done by retrieving the data from the formats list of the isp entity. This cause a crash when the media bus code on the source is YUYV8_1_5X8 which is not supported by the isp entity. Instead we should test the sink format of the resizer which is guaranteed to be supported by the isp entity.

There are places in the camss driver where camss_get_pixel_clock() is called to get the pixel rate (using V4L2_CID_PIXEL_RATE control) and to calculate the link frequency from it. There is a case when this would not work: when V4L2_CID_PIXEL_RATE gets the rate at which the pixels are read (sampled) from the sensor's pixel array, and this rate is different from the pixel transmission rate over the CSI link, the link frequency value can't be calculated from the pixel rate. One needs to use V4L2_CID_LINK_FREQ to get the link frequency in this case. Replace such calls to camss_get_pixel_clock() with calls to a wrapper around v4l2_get_link_freq(). v4l2_get_link_freq() tries V4L2_CID_LINK_FREQ first, and if it is not implemented by the camera sensor driver, falls back to V4L2_CID_PIXEL_RATE to calculate the link frequency value from. Calls to camss_get_pixel_clock() from vfe_[check,set]_clock_rates() are left intact as it looks like this VFE clock does depend on the rate the pixel samples comes out of the camera sensor, not on the frequency at which the link between the sensor and the CSI receiver operates.

Constify two static structs which are never modified to allow the compiler to put them in read-only memory. The only usage of norm_params is only read from it in usbtv_configure_for_norm(). Making it const shrinks the resulting ko-file with 300 bytes (tested with gcc 10). The only usage of usbtv_ioctl_ops is to put its address to the ioctl_ops field in the video_device struct. Making it const moves ~1kb to read-only memory. Signed-off-by:
