2017-03-06usb: dwc3: gadget: Fix system suspend/resume on TI platformsRoger Quadros
On TI platforms (dra7, am437x), the DWC3_DSTS_DEVCTRLHLT bit is not set after the device controller is stopped via DWC3_DCTL_RUN_STOP. If we don't disconnect and stop the gadget, it stops working after a system resume with the trace below. There is no point in preventing gadget disconnect and gadget stop during system suspend/resume as we're going to suspend in any case, whether DEVCTRLHLT timed out or not.

The user space application (e.g. uvc-gadget) is responsible for sending response to UVC class specific requests on control endpoint in uvc_send_response() in uvc_v4l2.c. The bad commit was causing a duplicate response to be sent with incorrect response data thus causing UVC probe to fail at the host and broken control transfer endpoint at the gadget.

2017-03-06HID: sony: Fix input device leak when connecting a DS4 twice using USB/BTRoderick Colenbrander
When a user connects a DS4 twice using USB and BT, we reject the second device connection after the setup work. We then perform a cleanup, but during cleanup we are not removing the touchpad device. This leads to leakage of an input device, which we would never remove. It can likely result into a kernel oops as well when the touchpad evdev node is accessed and the underlaying HID device has been removed from the system.

When CONFIG_OF is disabled, this always fails, and g_fragments_base is guaranteed to be NULL when vchiq_complete_bulk() gets called. This adds a CONFIG_OF Kconfig dependency, which is also technically correct but nonobvious, and thus seems like a good fit for the warning.

2017-03-06pinctrl: qcom: add get_direction functionTimur Tabi
The get_direction callback function allows gpiolib to know the current direction (input vs output) for a given GPIO. This is particularly useful on ACPI systems, where the GPIOs are configured only by firmware (typically UEFI), so the only way to know the initial values to query the hardware directly.

2017-03-06gpio: altera: Use handle_level_irq when configured as a level_highPhil Reid
When a threaded irq handler is chained attached to one of the gpio pins when configure for level irq the altera_gpio_irq_leveL_high_handler does not mask the interrupt while being handled by the chained irq. This resulting in the threaded irq not getting enough cycles to complete quickly enough before the irq was disabled as faulty. handle_level_irq should be used in this situation instead of handle_simple_irq. In gpiochip_irqchip_add set default handler to handle_bad_irq as per Documentation/gpio/driver.txt. Then set the correct handler in the set_type callback.

2017-03-06[media] dw2102: don't do DMA on stackJonathan McDowell
On Kernel 4.9, WARNINGs about doing DMA on stack are hit at the dw2102 driver: one in su3000_power_ctrl() and the other in tt_s2_4600_frontend_attach(). Both were due to the use of buffers on the stack as parameters to dvb_usb_generic_rw() and the resulting attempt to do DMA with them. The device was non-functional as a result. So, switch this driver over to use a buffer within the device state structure, as has been done with other DVB-USB drivers. Tested with TechnoTrend TT-connect S2-4600.

2017-03-06powerpc: Sort the selects under CONFIG_PPCMichael Ellerman
We have a big list of selects under CONFIG_PPC, and currently they're completely unsorted. This means people tend to add new selects at the bottom of the list, and so two commits which both add a new select will often conflict. Instead sort it alphabetically. This is nicer in and of itself, but also means two commits that add a new select will have a greater chance of not conflicting. Add a note at the top and bottom asking people to keep it sorted. And while we're here pad out the 'if' expressions to make them stand out. Suggested-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

2017-03-06powerpc: Update to new option-vector-5 format for CASSuraj Jitindar Singh
On POWER9 the ibm,client-architecture-support (CAS) negotiation process has been updated to change how the host to guest negotiation is done for the new hash/radix mmu as well as the nest mmu, process tables and guest translation shootdown (GTSE). This is documented in the unreleased PAPR ACR "CAS option vector additions for P9". The host tells the guest which options it supports in ibm,arch-vec-5-platform-support. The guest then chooses a subset of these to request in the CAS call and these are agreed to in the ibm,architecture-vec-5 property of the chosen node. Thus we read ibm,arch-vec-5-platform-support and make our selection before calling CAS. We then parse the ibm,architecture-vec-5 property of the chosen node to check whether we should run as hash or radix. ibm,arch-vec-5-platform-support format: index value pairs: <index, val> ... <index, val> index: Option vector 5 byte number val: Some representation of supported values Signed-off-by: Suraj Jitindar Singh <sjitindarsingh@gmail.com> Acked-by: Paul Mackerras <paulus@ozlabs.org> [mpe: Don't print about unknown options, be consistent with OV5_FEAT] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2017-03-06powerpc: Parse the command line before calling CASSuraj Jitindar Singh
On POWER9 the hypervisor requires the guest to decide whether it would like to use a hash or radix mmu model at the time it calls ibm,client-architecture-support (CAS) based on what the hypervisor has said it's allowed to do. It is possible to disable radix by passing "disable_radix" on the command line. The next patch will add support for the new CAS format, thus we need to parse the command line before calling CAS so we can correctly select which mmu we would like to use.
