Device-tree users simply defined an appropriate regulator, while two boards with no DT support (da830-evm and omapl138-hawk) passed functions defined in their respective board files over platform data. These functions simply used legacy GPIO calls to watch the oc GPIO for interrupts and disable the vbus GPIO when the irq fires. Commit d193abf1c913 ("usb: ohci-da8xx: add vbus and overcurrent gpios") updated these GPIO calls to the modern API and moved them inside the driver. This however is not the optimal solution for the vbus GPIO which should be modeled as a fixed regulator that can be controlled with a GPIO. In order to keep the overcurrent protection available once we move the board files to using fixed regulators we need to disable the enable_reg regulator when the overcurrent indicator interrupt fires. Since we cannot call regulator_disable() from interrupt context, we need to switch to using a oneshot threaded interrupt.

This avoids the somewhat expensive DMA mappings that are performed by default on most URBs submissions. In the case an URB was suitable for IDT. The data is directly copied into the "Data Buffer Pointer" region of the TRB and the IDT flag is set. Instead of triggering memory accesses the HC will use the data directly. The implementation could cover all kind of output endpoints. Yet Isochronous endpoints are bypassed as I was unable to find one that matched IDT's constraints. As we try to bypass the default DMA mappings on URB buffers we'd need to find a Isochronous device with an urb->transfer_buffer_length <= 8 bytes. The implementation takes into account that the 8 byte buffers provided by the URB will never cross a 64KB boundary.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

* | xhci: Don't let USB3 ports stuck in polling state prevent suspendMathias Nyman2019-03-222-7/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2f31a67f01a8 ("usb: xhci: Prevent bus suspend if a port connect change or polling state is detected") was intended to prevent ports that were still link training from being forced to U3 suspend state mid enumeration. This solved enumeration issues for devices with slow link training. Turns out some devices are stuck in the link training/polling state, and thus that patch will prevent suspend completely for these devices. This is seen with USB3 card readers in some MacBooks. Instead of preventing suspend, give some time to complete the link training. On successful training the port will end up as connected and enabled. If port instead is stuck in link training the bus suspend will continue suspending after 360ms (10 * 36ms) timeout (tPollingLFPSTimeout). Original patch was sent to stable, this one should go there as well Fixes: 2f31a67f01a8 ("usb: xhci: Prevent bus suspend if a port connect change or polling state is detected") Cc: stable@vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

It is done by the core automatically and doing it twice would increment the phy->powercount counter to 2 instead of 1. During later suspend operation, the counter will be decremented to one, no phy->power_off() will occur and worse than that, the following phy->power_on() at resume time will also be skipped, failing the whole S2RAM operation.

For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.
