2020-09-26media: mtk-vcodec: abstract firmware interfaceYunfei Dong
MT8183's codec firmware is run by a different remote processor from MT8173. While the firmware interface is basically the same, the way to invoke it differs. Abstract all firmware calls under a layer that will allow us to handle both firmware types transparently.

When adding the support for TBF offload, the improper command version was added even though the command format is for the V2 of dpni_set_tx_shaping(). This does not affect the functionality of TBF since the only change between these two versions is the addition of the exceeded parameters which are not used in TBF.

CLK_TO_US macro is used to calculate potential transfer time for various timeout handling. However it overflows on transfer bigger than 512 bytes because it first did (len * 8 * 1000000). This controller typically operates at 45MHz.

2020-09-25irqchip: Add Actions Semi Owl SIRQ controllerCristian Ciocaltea
This interrupt controller is found in the Actions Semi Owl SoCs (S500, S700 and S900) and provides support for handling up to 3 external interrupt lines. Each line can be independently configured as interrupt and triggers on either of the edges or either of the levels. Additionally, each line can also be masked individually.

2020-09-25io_uring: don't unconditionally set plug->nowait = trueJens Axboe
This causes all the bios to be submitted with REQ_NOWAIT, which can be problematic on either btrfs or on file systems that otherwise use a mix of block devices where only some of them support it.

2020-09-25usbcore/driver: Accommodate usbipM. Vefa Bicakci
Commit 88b7381a939d ("USB: Select better matching USB drivers when available") inadvertently broke usbip functionality. The commit in question allows USB device drivers to be explicitly matched with USB devices via the use of driver-provided identifier tables and match functions, which is useful for a specialised device driver to be chosen for a device that can also be handled by another, more generic, device driver. Prior, the USB device section of usb_device_match() had an unconditional "return 1" statement, which allowed user-space to bind USB devices to the usbip_host device driver, if desired. However, the aforementioned commit changed the default/fallback return value to zero. This breaks device drivers such as usbip_host, so this commit restores the legacy behaviour, but only if a device driver does not have an id_table and a match() function. In addition, if usb_device_match is called for a device driver and device pair where the device does not match the id_table of the device driver in question, then the device driver will be disqualified for the device. This allows avoiding the default case of "return 1", which prevents undesirable probe() calls to a driver even though its id_table did not match the device. Finally, this commit changes the specialised-driver-to-generic-driver transition code so that when a device driver returns -ENODEV, a more generic device driver is only considered if the current device driver does not have an id_table and a match() function. This ensures that "generic" drivers such as usbip_host will not be considered specialised device drivers and will not cause the device to be locked in to the generic device driver, when a more specialised device driver could be tried. All of these changes restore usbip functionality without regressions, ensure that the specialised/generic device driver selection logic works as expected with the usb and apple-mfi-fastcharge drivers, and do not negatively affect the use of devices provided by dummy_hcd.
