2017-06-14RDMA/bnxt_re: Add HW workaround for avoiding stall for UD QPsSomnath Kotur
HW stalls out after 0x800000 WQEs are posted for UD QPs. To workaround this problem, driver will send a modify_qp cmd to the HW at around the halfway mark(0x400000) so that FW can accordingly modify the QP context in the HW to prevent this stall. This workaround needs to be done for UD, QP1 and Raw Ethertype packets. Added a counter to keep track of WQEs posted during post_send.

2017-06-14RDMA/bnxt_re: HW workarounds for handling specific conditionsEddie Wai
This patch implements the following HW workarounds 1. The SQ depth needs to be augmented by 128 + 1 to avoid running into an Out of order CQE issue 2. Workaround to handle the problem where the HW fast path engine continues to access DMA memory in retranmission mode even after the WQE has already been completed. If the HW reports this condition, driver detects it and posts a Fence WQE. The driver stops reporting the completions to stack until it receives completion for Fence WQE.

2017-06-14powerpc/npu-dma: Remove spurious WARN_ON when a PCI device has no of_nodeAlistair Popple
Commit 4c3b89effc28 ("powerpc/powernv: Add sanity checks to pnv_pci_get_{gpu|npu}_dev") introduced explicit warnings in pnv_pci_get_npu_dev() when a PCIe device has no associated device-tree node. However not all PCIe devices have an of_node and pnv_pci_get_npu_dev() gets indirectly called at least once for every PCIe device in the system. This results in spurious WARN_ON()'s so remove it. The same situation should not exist for pnv_pci_get_gpu_dev() as any NPU based PCIe device requires a device-tree node.

2017-06-13HID: let generic driver yield control iff specific driver has been enabledJiri Kosina
There are many situations where generic HID driver provides some basic level of support for certain device, but later this support (usually by implementing vendor-specific extensions of HID protocol) is extended and the support moved over to a separate (usually per-vendor) specific driver. This might bring a rather unpleasant suprise for users, as all of a sudden there is a new config option they have to enable in order to get any support for their device whatsoever, although previous kernel versions provided basic support through the generic driver. Which is rightfully seen as a regression. Fix this by including the entry for a particular device in hid_have_special_driver[] iff the specific config option has been specified, and let generic driver handle the device otherwise. Also make the behavior of hid_scan_report() (where the same decision is being taken on a per-report level) consistent. While at it, reshuffle the hid_have_special_driver[] a bit to restore the alphabetical ordering (first order by config option, and within those sections order by VID). This is considered a short-term solution, before generic way of giving precedence to special drivers and falling back to generic driver is figured out. While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for spotting this (and for discovering a few issues in the conversion). Signed-off-by: Jiri Kosina <jkosina@suse.cz>

If PHY is suspended by the time we want to issue ULPI transfers, we will observe timeouts on the ULPI interface. In order to avoid such issue, let's make sure PHY is resumed before issuing a ULPI transfer. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

2017-06-13usb: gadget: core: introduce ->udc_set_speed() methodFelipe Balbi
Sometimes, the gadget driver we want to run has max_speed lower than what the UDC supports. In such situations, UDC might want to make sure we don't try to connect on speeds not supported by the gadget driver (e.g. super-speed capable dwc3 with high-speed capable g_midi) because that will just fail. In order to make sure this situation never happens, we introduce a new optional ->udc_set_speed() method which can be implemented by interested UDC drivers.

2017-06-13usb: gadget: udc: Add Synopsys UDC Platform driverRaviteja Garimella
This patch adds platform driver support for Synopsys UDC. A new driver file (snps_udc_plat.c) is created for this purpose where the platform driver registration is done based on OF node. Currently, UDC integrated into Broadcom's iProc SoCs (Northstar2 and Cygnus) work with this driver. New members are added to the UDC data structure for having platform device support along with extcon and phy support. Kconfig and Makefiles are modified to select platform driver for compilation.
