In [1], Christoph Hellwig has proposed to remove the wrappers in include/linux/pci-dma-compat.h. Some reasons why this API should be removed have been given by Julia Lawall in [2].

hdpvr_register_videodev is responsible to initialize a worker in hdpvr_device. However, the worker is only initialized at hdpvr_start_streaming other than hdpvr_register_videodev. When hdpvr_probe does not initialize its worker, the hdpvr_disconnect will encounter one WARN in flush_work.The stack trace is as follows: hdpvr_disconnect+0xb8/0xf2 drivers/media/usb/hdpvr/hdpvr-core.c:425 usb_unbind_interface+0xbf/0x3a0 drivers/usb/core/driver.c:458 __device_release_driver drivers/base/dd.c:1206 [inline] device_release_driver_internal+0x22a/0x230 drivers/base/dd.c:1237 bus_remove_device+0x108/0x160 drivers/base/bus.c:529 device_del+0x1fe/0x510 drivers/base/core.c:3592 usb_disable_device+0xd1/0x1d0 drivers/usb/core/message.c:1419 usb_disconnect+0x109/0x330 drivers/usb/core/hub.c:2228 Fix this by moving the initialization of dev->worker to the starting of hdpvr_register_videodev Reported-by:

Reviewing the RB5 schematic its clear that we have missed out on defining both of the power-rails associated with the CSI PHY. Other PHYs such as the UFS, PCIe and USB connect to these rails and define each regulator individually. This means if we were to switch off the other various PHYs which enable these rails, the CAMSS would not appropriately power-on the CSI PHY. Reviewed-by:

Add the ability to enable or disable multiple regulators in bulk with camss. This is useful for sm8250, sdm845 and it looks like sdm660 where we have more than one CSI regulator to do at once. It should just work for standalone existing vdda regulators and parts which don't have an explicitly defined CSI regulator.

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq_optional(). While at it, propagate error code in case devm_request_irq() fails instead of returning -EINVAL. Signed-off-by:

As the possible failure of the vzalloc(), e->encoder_buf might be NULL. Therefore, it should be better to check it in order to guarantee the success of the initialization. If fails, we need to free not only 'e' but also 'e->name'. Also, if the allocation for ctx fails, we need to free 'e->encoder_buf' else.

Replace the urb buffers allocation to use the noncontiguous API. This improves performance on ARM platforms where DMA coherent allocations produce uncached mappings.

The VPU in the i.MX8MQ is really the combination of Hantro G1 and Hantro G2. With the updated vpu-blk-ctrl, the power domains system can enable and disable them separately as well as pull them out of reset. This simplifies the code and lets them run independently while still retaining backwards compatibility with older device trees for those using G1. Signed-off-by:

Adam Ford authored
The G1 and G2 are independent and separate decoder blocks that are enabled by the vpu-blk-ctrl power-domain controller, which now has a proper driver. Because these blocks only share the power-domain, and can be independently fused out, update the bindings to support separate nodes for the G1 and G2 decoders with vpu-blk-ctrl power-domain support. The new DT + old kernel isn't a supported configuration. Signed-off-by:

During encoder driver open controls are initialized via a call to v4l2_ctrl_handler_setup which returns EINVAL error for V4L2_CID_MPEG_VIDEO_H264_8X8_TRANSFORM v4l2 control. The control default value is disabled and because of firmware limitations 8x8 transform cannot be disabled for the supported HIGH and CONSTRAINED_HIGH profiles. To fix the issue change the control default value to enabled (this is fine because the firmware enables 8x8 transform for high and constrained_high profiles by default). Also, correct the checking of profile ids in s_ctrl from hfi to v4l2 ids. cc: stable@vger.kernel.org # 5.15+ Fixes: bfee75f7 ("media: venus: venc: add support for V4L2_CID_MPEG_VIDEO_H264_8X8_TRANSFORM control") Signed-off-by:

VSP hardware could be used (e.g. by the bootloader) before driver load, and some interrupts could be left in enabled and pending state. In this case, setting up VSP interrupt handler without masking interrupts before causes interrupt handler to be immediately called (and crash due to null vsp->info dereference). Fix that by explicitly masking all interrupts before setting the interrupt handler. To do so, have to set the interrupt handler later, after hw revision is already detected and number of interrupts to mask gets known.
