2017-05-04Merge tag 'usb-4.12-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb Pull USB updates from Greg KH: "Here is the big USB patchset for 4.12-rc1. Lots of good stuff here, after many many many attempts, the kernel finally has a working typeC interface, many thanks to Heikki and Guenter and others who have taken the time to get this merged. It wasn't an easy path for them at all. There's also a staging driver that uses this new api, which is why it's coming in through this tree. Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff. Johan also finally refactored pretty much every driver that was looking at USB endpoints to do it in a common way, which will help prevent any "badly-formed" devices from causing problems in drivers. That too wasn't a simple task. All of these have been in linux-next for a while with no reported issues" * tag 'usb-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (263 commits) staging: typec: Fairchild FUSB302 Type-c chip driver staging: typec: Type-C Port Controller Interface driver (tcpci) staging: typec: USB Type-C Port Manager (tcpm) usb: host: xhci: remove #ifdef around PM functions usb: musb: don't mark of_dev_auxdata as initdata usb: misc: legousbtower: Fix buffers on stack USB: Revert "cdc-wdm: fix "out-of-sync" due to missing notifications" usb: Make sure usb/phy/of gets built-in USB: storage: e-mail update in drivers/usb/storage/unusual_devs.h usb: host: xhci: print correct command ring address usb: host: xhci: delete sp_dma_buffers for scratchpad usb: host: xhci: using correct specification chapter reference for DCBAAP xhci: switch to pci_alloc_irq_vectors usb: host: xhci-plat: set resume_quirk() for R-Car controllers usb: host: xhci-plat: add resume_quirk() usb: host: xhci-plat: enable clk in resume timing usb: host: plat: Enable xHCI plat runtime PM USB: serial: ftdi_sio: add device ID for Microsemi/Arrow SF2PLUS Dev Kit USB: serial: constify static arrays usb: fix some references for /proc/bus/usb ...

2017-05-04IB/rxe: Update caller's CRC for RXE_MEM_TYPE_DMA memory typeLeon Romanovsky
Callers of rxe_mem_copy() provide pointer to store updated CRC value. That pointer was supposed to be updated, but the commit cee2688e3cd6 ("IB/rxe: Offload CRC calculation when possible") mistakenly removed that assignment for RXE_MEM_TYPE_DMA memory type. The code worked because there are no actual callers with RXE_MEM_TYPE_DMA, who are interested in returned value of crcp. The one caller in read_reply(), who uses the returned crcp didn't set RXE_MEM_TYPE_DMA as mem->type.

The error path for context initialization is not consistent. Cleanup all resources on failure. Removed unused variable user_event_mask. Add the _BASE_FAILED bit to the event flags so that a base context can notify waiting sub contexts that they cannot continue. Running out of sub contexts is an EBUSY result, not EINVAL.

2017-05-04IB/hfi1: Fix an assign/ordering issue with shared context IDsMichael J. Ruhl
The current algorithm for generating sub-context IDs is FILO. If the contexts are not closed in that order, the uniqueness of the ID will be compromised. I.e. logging the creation/deletion of context IDs with an application that assigns and closes in a FIFO order reveals: cache_id: assign: uctxt: 3 sub_ctxt: 0 cache_id: assign: uctxt: 3 sub_ctxt: 1 cache_id: assign: uctxt: 3 sub_ctxt: 2 cache_id: close: uctxt: 3 sub_ctxt: 0 cache_id: assign: uctxt: 3 sub_ctxt: 2 <<< The sub_ctxt ID 2 is reused incorrectly. Update the sub-context ID assign algorithm to use a bitmask of in_use contexts. The new algorithm will allow the contexts to be closed in any order, and will only re-use unused contexts. Size subctxt and subctxt_cnt to match the user API size. Reviewed-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Michael J.

2017-05-04IB/hfi1: Clean up context initializationMichael J. Ruhl
Context initialization mixes base context init with sub context init. This is bad because contexts can be reused, and on reuse, reinit things that should not re-initialized. Normalize comments and function names to refer to base context and sub context (not main, shared or slaves). Separate the base context initialization from sub context initialization. hfi1_init_ctxt() cannot return an error so changed to a void and remove error message.

2017-05-04IB/hfi1: Search shared contexts on the opened device, not all devicesMichael J. Ruhl
The search for available shared contexts walks each registered hfi1 device. This search is too broad because other devices may not be on the same fabric, and using its contexts could cause unexpected behavior. Removed walking the list of devices, limiting the search to the opened device. With the device walk removed, the hfi1_devdata (dd) is not available. Added it to the hfi1_filedata for reference. With this change, hfi1_count_units() was rendered obsolete and was removed. Reviewed-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Michael J.

2017-05-04IB/hfi1: Fix a subcontext memory leakMichael J. Ruhl
The only context that frees user_exp_rcv data structures is the last context closed (from a sub-context set). This leaks the allocations from the other sub-contexts. Separate the common frees from the specific frees and call them at the appropriate time. Using KEDR to check for memory leaks we get: Before test: [leak_check] Possible leaks: 25 After test: [leak_check] Possible leaks: 31 (6 leaked data structures) After patch applied (before and after test have the same value) [leak_check] Possible leaks: 25 Each leak is 192 + 13440 + 6720 = 20352 bytes per sub-context.

2017-05-04IB/hfi1: Fix yield logic in send engineMike Marciniszyn
When there are many RC QPs and an RDMA READ request is sent, timeouts occur on the requester side because of fairness among RC QPs on their relative SDMA engine on the responder side. This also hits write and send, but to a lesser extent. Complicating the issue is that the current code checks if workqueue is congested before scheduling other QPs, however, this check is based on the number of active entries in the workqueue, which was found to be too big to for workqueue_congested() to be effective. Fix by reducing the number of active entries as revealed by experimentation from the default of num_sdma to HFI1_MAX_ACTIVE_WORKQUEUE_ENTRIES. Retry counts were monitored to determine the correct value. Tracing to investigate any future issues is also added.

2017-05-04power: supply: cpcap-charger: Keep trickle charger bits disabledTony Lindgren
Android does not seem to set the trickle charger bits, and these seem to be only used by the bootloader when bringing up a completely discharged battery. So let's keep the trickle charging bits disabled and avoid misconfiguring the hardware.

2017-05-04power: supply: cpcap-charger: Fix charge voltage configurationTony Lindgren
We have the charge voltage wrong, it should be 4.35V instead of 4.2V. This will cause the battery to never get fully charged. I noticed this when looking at the Andoid kernel battery and charger status for a fully charged battery: POWER_SUPPLY_VOLTAGE_NOW=4351000 Also the battery on droid 4 says "4.35, 1735/1785mAh (min/typ), 6.6/6.8 Wh (min/typ)". Presumably the 4.35 on the battery is the charge voltage. And finally, on Android the CPCAP CRM register is set to 0x03b5 where the b is the charge voltage. Let's fix the charge voltage define and update the charge configuration to use the 4.35V setting.

On Android we have the following for droid 4: $ ls /sys/class/power_supply/ ac battery usb So let's use the usb naming here for charger too.
