These two HW of wakeup don't follow MediaTek internal IPM rule, and both use a specific way, like as early revision of mt8173. Due to the index 2 already used by many DTS, it's better to keep it unchanged for backward compatibility, treat specific ones without following IPM rule as revision 1.x, meanwhile reserve 3~99 for later revision that following the IPM rule.

The newer usb_control_msg_{send|recv}() API ensures that a short read is treated as an error, data can be used off the stack, and raw usb pipes need not be created in the calling functions. For this reason, instances of usb_control_msg() have been replaced with usb_control_msg_send() appropriately.

For this reason, instances of usb_control_msg() have been replaced with usb_control_msg_{recv|send}() appropriately. Now, we also test for a short device descriptor (which USB core should already have fetched if you get to probe this driver), but which wasn't verified again here before.

For a 75 Byte request, it would send the first 64 separately, then detect that the remaining 11 Byte fit into a single DMA, but due to this bug set the length to the original 75 Bytes. This leads to a DMA failure (which is ignored...) and the request completes without the remaining bytes having been sent.

Currently dwc3 only prints the virtual address of a register when doing register read/write. However, these hashed addresses are difficult to read. Also, since we use %p, we may get some useless (___ptrval___) prints if the address is not randomized enough. Let's include the register offset to help read the register read and write tracepoints.

The commit d3cb25a1 ("usb: gadget: udc: fix spin_lock in pch_udc") obviously was not thought through and had made the situation even worse than it was before. Two changes after almost reverted it. but a few leftovers have been left as it. With this revert d3cb25a1 completely.

Thinh Nguyen authored
The current xhci_create_usb3_bos_desc() uses a static bos u8 array and various magic numbers and offsets making it difficult to extend support for USB 3.2. Let's rewrite this entire function to support dual-lane in USB 3.2. The hub driver matches the port speed ID from the extended port status to the SSID of the sublink speed attributes to detect if the device supports SuperSpeed Plus. Currently we don't provide the default gen1x2 and gen2x2 sublink speed capability descriptor for USB 3.2 roothub. The USB stack depends on this to detect and match the correct speed. In addition, if the xHCI host provides Protocol Speed ID (PSI) capability, then make sure to convert Protocol Speed ID Mantissa and Exponent (PSIM & PSIE) to lane speed for gen1x2 and gen2x2.

Some hosts incorrectly use sub-minor version for minor version (i.e. 0x02 instead of 0x20 for bcdUSB 0x320 and 0x01 for bcdUSB 0x310). Currently the xHCI driver works around this by just checking for minor revision > 0x01 for USB 3.1 everywhere. With the addition of USB 3.2, checking this gets a bit cumbersome. Since there is no USB release with bcdUSB 0x301 to 0x309, we can assume that sub-minor version 01 to 09 is incorrect. Let's try to fix this and use the minor revision that matches with the USB/xHCI spec to help with the version checking within the driver. Acked-by:
