Add support ip-sleep wakeup for MT8183, it's similar to MT8173, and it's also a specific one, but not following IPM rule. 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 3~10 for later revision that follows the IPM rule.

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 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:

The current dwc3_gadget_reset_interrupt() will stop any active transfers, but only addresses blocking of EP queuing for while we are coming from a disconnected scenario, i.e. after receiving the disconnect event. If the host decides to issue a bus reset on the device, the connected parameter will still be set to true, allowing for EP queuing to continue while we are disabling the functions. To avoid this, set the connected flag to false until the stop active transfers is complete. Signed-off-by:

Add checks similar to dwc3_gadget_ep_queue() before kicking off transfers after getting an endpoint completion event. Since cleaning up completed requests will momentarily unlock dwc->lock, there is a chance for a sequence like pullup disable to be executed.

Force-threaded interrupt handlers used to run with interrupts enabled, something which could lead to deadlocks in case a threaded handler shared a lock with code running in hard interrupt context (e.g. timer callbacks) and did not explicitly disable interrupts. Since commit 81e2073c ("genirq: Disable interrupts for force threaded handlers") interrupt handlers always run with interrupts disabled on non-RT so that drivers no longer need to do handle forced threading ("threadirqs"). Drop the now obsolete workaround added by commit 63aea0db ("USB: xhci: fix lock-inversion problem").
