2024-09-05usb: xhci: add comments explaining specific interrupt behaviourNiklas Neronin
HCD does not allocate or request interrupt for the xhci driver, but HCD does free and sync xhci interrupts in some cases. Add comment detailing in which cases HCD will free/sync xhci interrupts.

2024-09-05usb: xhci: make 'sbrn' a local variableNiklas Neronin
Variable 'sbrn' is used to store the Serial Bus Release Number, which is then only used for a debug message. Thus, 'sbrn' can be a local variable and assigned after the primary HCD check. The SBRN debug message is only printed when a primary HCD is setup.

2024-09-05usb: xhci: remove excessive Bulk short packet debug messageNiklas Neronin
Completion codes 'COMP_SUCCESS' and 'COMP_SHORT_PACKET' are the most frequently encountered completion codes. Typically, these codes do not trigger a default debug message but rather a warning that indicates a potential issue. This behavior is consistent across all transfer types with the exception of Bulk transfers. To reduce unnecessary log clutter, remove the Bulk 'COMP_SHORT_PACKET' debug message.

2024-09-05xhci: dbc: Fix STALL transfer event handlingMathias Nyman
Don't flush all pending DbC data requests when an endpoint halts. An endpoint may halt and xHC DbC triggers a STALL error event if there's an issue with a bulk data transfer. The transfer should restart once xHC DbC receives a ClearFeature(ENDPOINT_HALT) request from the host. Once xHC DbC restarts it will start from the TRB pointed to by dequeue field in the endpoint context, which might be the same TRB we got the STALL event for. Turn the TRB to a no-op in this case to make sure xHC DbC doesn't reuse and tries to retransmit this same TRB after we already handled it, and gave its corresponding data request back. Other STALL events might be completely bogus. Lukasz Bartosik discovered that xHC DbC might issue spurious STALL events if hosts sends a ClearFeature(ENDPOINT_HALT) request to non-halted endpoints even without any active bulk transfers. Assume STALL event is spurious if it reports 0 bytes transferred, and the endpoint stopped on the STALLED TRB. Don't give back the data request corresponding to the TRB in this case. The halted status is per endpoint. Track it with a per endpoint flag instead of the driver invented DbC wide DS_STALLED state. DbC remains in DbC-Configured state even if endpoints halt. There is no Stalled state in the DbC Port state Machine (xhci section 7.6.6) Reported-by: Łukasz Bartosik <ukaszb@chromium.org> Closes: https://lore.kernel.org/linux-usb/20240725074857.623299-1-ukaszb@chromium.org/ Tested-by: Łukasz Bartosik <ukaszb@chromium.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20240905143300.1959279-2-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2024-09-05of: address: Report error on resource bounds overflowThomas Weißschuh
The members "start" and "end" of struct resource are of type "resource_size_t" which can be 32bit wide. Values read from OF however are always 64bit wide. Avoid silently truncating the value and instead return an error value. This can happen on real systems when the DT was created for a PAE-enabled kernel and a non-PAE kernel is actually running. For example with an arm defconfig and "qemu-system-arm -M virt".

The commit 783bf5d09f86 ("spi: spi-fsl-lpspi: limit PRESCALE bit in TCR register") doesn't implement the prescaler maximum as intended. The maximum allowed value for i.MX93 should be 1 and for i.MX7ULP it should be 7. So this needs also a adjustment of the comparison in the scldiv calculation.

2024-09-05ptp: ptp_idt82p33: Convert comma to semicolonChen Ni
Replace comma between expressions with semicolons. Using a ',' in place of a ';' can have unintended side effects. Although that is not the case here, it is seems best to use ';' unless ',' is intended. Found by inspection. No functional change intended. Compile tested only.
