2021-11-23USB: serial: pl2303: fix GC type detectionJohan Hovold
At least some PL2303GC have a bcdDevice of 0x105 instead of 0x100 as the datasheet claims. Add it to the list of known release numbers for the HXN (G) type. Note the chip type could only be determined indirectly based on its package being of QFP type, which appears to only be available for PL2303GC.

2021-11-17usb: hub: Fix usb enumeration issue due to address0 raceMathias Nyman
xHC hardware can only have one slot in default state with address 0 waiting for a unique address at a time, otherwise "undefined behavior may occur" according to xhci spec 5.4.3.4 The address0_mutex exists to prevent this across both xhci roothubs. If hub_port_init() fails, it may unlock the mutex and exit with a xhci slot in default state. If the other xhci roothub calls hub_port_init() at this point we end up with two slots in default state. Make sure the address0_mutex protects the slot default state across hub_port_init() retries, until slot is addressed or disabled. Note, one known minor case is not fixed by this patch. If device needs to be reset during resume, but fails all hub_port_init() retries in usb_reset_and_verify_device(), then it's possible the slot is still left in default state when address0_mutex is unlocked.

2021-11-17usb: typec: fusb302: Fix masking of comparator and bc_lvl interruptsOndrej Jirman
The code that enables either BC_LVL or COMP_CHNG interrupt in tcpm_set_cc wrongly assumes that the interrupt is unmasked by writing 1 to the apropriate bit in the mask register. In fact, interrupts are enabled when the mask is 0, so the tcpm_set_cc enables interrupt for COMP_CHNG when it expects BC_LVL interrupt to be enabled. This causes inability of the driver to recognize cable unplug events in host mode (unplug is recognized only via a COMP_CHNG interrupt). In device mode this bug was masked by simultaneous triggering of the VBUS change interrupt, because of loss of VBUS when the port peer is providing power.

2021-11-17usb: dwc2: hcd_queue: Fix use of floating point literalNathan Chancellor
A new commit in LLVM causes an error on the use of 'long double' when '-mno-x87' is used, which the kernel does through an alias, '-mno-80387' (see the LLVM commit below for more details around why it does this). drivers/usb/dwc2/hcd_queue.c:1744:25: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it delay = ktime_set(0, DWC2_RETRY_WAIT_DELAY); ^ drivers/usb/dwc2/hcd_queue.c:62:34: note: expanded from macro 'DWC2_RETRY_WAIT_DELAY' #define DWC2_RETRY_WAIT_DELAY (1 * 1E6L) ^ 1 error generated. This happens due to the use of a 'long double' literal. The 'E6' part of '1E6L' causes the literal to be a 'double' then the 'L' suffix promotes it to 'long double'. There is no visible reason for a floating point value in this driver, as the value is only used as a parameter to a function that expects an integer type. Use NSEC_PER_MSEC, which is the same integer value as '1E6L', to avoid changing functionality but fix the error.

2021-11-17usb: dwc3: gadget: Check for L1/L2/U3 for Start TransferThinh Nguyen
The programming guide noted that the driver needs to verify if the link state is in U0 before executing the Start Transfer command. If it's not in U0, the driver needs to perform remote wakeup. This is not accurate. If the link state is in U1/U2, then the controller will not respond to link recovery request from DCTL.ULSTCHNGREQ. The Start Transfer command will trigger a link recovery if it is in U1/U2. A clarification will be added to the programming guide for all controller versions. The current implementation shouldn't cause any functional issue. It may occasionally report an invalid time out warning from failed link recovery request. The driver will still go ahead with the Start Transfer command if the remote wakeup fails. The new change only initiates remote wakeup where it is needed, which is when the link state is in L1/L2/U3.

2021-11-17usb: gadget: f_fs: Use stream_open() for endpoint filesPavankumar Kondeti
Function fs endpoint file operations are synchronized via an interruptible mutex wait. However we see threads that do ep file operations concurrently are getting blocked for the mutex lock in __fdget_pos(). This is an uninterruptible wait and we see hung task warnings and kernel panic if hung_task_panic systcl is enabled if host does not send/receive the data for long time. The reason for threads getting blocked in __fdget_pos() is due to the file position protection introduced by the commit 9c225f2655e3 ("vfs: atomic f_pos accesses as per POSIX"). Since function fs endpoint files does not have the notion of the file position, switch to the stream mode. This will bypass the file position mutex and threads will be blocked in interruptible state for the function fs mutex. It should not affects user space as we are only changing the task state changes the task state from UNINTERRUPTIBLE to INTERRUPTIBLE while waiting for the USB transfers to be finished. However there is a slight change to the O_NONBLOCK behavior. Earlier threads that are using O_NONBLOCK are also getting blocked inside fdget_pos(). Now they reach to function fs and error code is returned. The non blocking behavior is actually honoured now.

2021-11-06xhci: Fix USB 3.1 enumeration issues by increasing roothub power-on-good delayMathias Nyman
Some USB 3.1 enumeration issues were reported after the hub driver removed the minimum 100ms limit for the power-on-good delay. Since commit 90d28fb53d4a ("usb: core: reduce power-on-good delay time of root hub") the hub driver sets the power-on-delay based on the bPwrOn2PwrGood value in the hub descriptor. xhci driver has a 20ms bPwrOn2PwrGood value for both roothubs based on xhci spec section 5.4.8, but it's clearly not enough for the USB 3.1 devices, causing enumeration issues. Tests indicate full 100ms delay is needed.
