2016-09-23pinctrl: intel: Configure GPIO chip IRQ as wakeup interruptsNilesh Bacchewar
On some Intel BXT platform, wake-up from suspend-to-idle on pressing power-button is not working. Its noticed that gpio-keys driver marking the second level IRQ/power-button as wake capable but Intel pintctrl driver is missing to mark GPIO chip/controller IRQ which first level IRQ as wake cable if its GPIO pin IRQ is wakeble. So, though the first level IRQ gets generated on power-button press, since it is not marked as wake capable resume/wake-up flow is not happening. Intel pintctrl/GPIO driver need to mark GPIO chip/controller IRQ (first level IRQ) as wake capable iff GPIO pin's IRQ (second level IRQ) is marked as wake cable. Changes in v2: - Add missing irq initialisation.

Implement the get_direction callback for the GPIOs found in the AXP209 PMIC. Due to the way they are implemented, in the same register you have the muxing options, GPIO directions and GPIO values.

2016-09-23pinctrl: cherryview: Do not add all southwest and north GPIOs to IRQ domainMika Westerberg
It turns out that for north and southwest communities, they can only generate GPIO interrupts for lower 8 interrupts (IntSel value). The upper part (8-15) can only generate GPEs (General Purpose Events). Now the reason why EC events such as pressing hotkeys does not work if we mask all the interrupts is that in order to generate either interrupts or GPEs the INTMASK register must have that particular interrupt unmasked. In case of GPEs the CPU does not trigger normal interrupt (and thus the GPIO driver does not see it) but instead it causes SCI (System Control Interrupt) to be triggered with the GPE in question set. To make this all work as expected we only add those GPIOs to the IRQ domain that can actually generate interrupts (IntSel value 0-7) and skip others.

2016-09-23gpiolib: Make it possible to exclude GPIOs from IRQ domainMika Westerberg
When using GPIO irqchip helpers to setup irqchip for a gpiolib based driver, it is not possible to select which GPIOs to add to the IRQ domain. Instead it just adds all GPIOs which is not always desired. For example there might be GPIOs that for some reason cannot generated normal interrupts at all. To support this we add a flag irq_need_valid_mask to struct gpio_chip. When this flag is set the core allocates irq_valid_mask that holds one bit for each GPIO the chip has. By default all bits are set but drivers can manipulate this using set_bit() and clear_bit() accordingly. Then when gpiochip_irqchip_add() is called, this mask is checked and all GPIOs with bit is set are added to the IRQ domain created for the GPIO chip.

2016-09-23net/mlx5: E-Switch, Support VLAN actions in the offloads modeOr Gerlitz
Many virtualization systems use a policy under which a vlan tag is pushed to packets sent by guests, and popped before the packet is forwarded to the VM. The current generation of the mlx5 HW doesn't fully support that on a per flow level. As such, we are addressing the above common use case with the SRIOV e-Switch abilities to push vlan into packets sent by VFs and pop vlan from packets forwarded to VFs. The HW can match on the correct vlan being present in packets forwarded to VFs (eSwitch steering is done before stripping the tag), so this part is offloaded as is. A common practice for vlans is to avoid both push vlan and pop vlan for inter-host VM/VM (east-west) communication because in this case, push on egress cancels out with pop on ingress. For supporting that, we use a global eswitch vlan pop policy, hence allowing guest A to communicate with both remote VM B and local VM C. This works since the HW pops the vlan only if it exists (e.g for C --> A packets but not for B --> A packets). On the slow path, when a VF vport has an offloaded flow which involves pushing vlans, wheres another flow is not currently offloaded, the packets from the 2nd flow seen by the VF representor on the host have vlan. The VF rep driver removes such vlan before calling into the host networking stack.

2016-09-23usb: musb: Fix session based PM for first invalid VBUSTony Lindgren
With the session bit based PM runtime working on musb, we've implemented few quirks to attempt to detect the current state of the hardware. One of the quirks is for invalid VBUS as peripheral, but it is not working in all cases. If we start musb on dm3730 as a peripheral with no cable connected, we will get the devctl 91 state once and will never idle as there are not further interrupts from musb. So we need to ignore the first devctl 91 state as there will be more interrupts if we're connected. The invalid VBUS state also can happen always when connected to certain USB hubs. Looks like musb on dm3730 can claim invalid VBUS with some hubs while 3717-evm and BeagleBone don't. This causes session as peripheral to fail for dm3730 with some hubs. This too is fixed by ignoring only the first invalid VBUS. When connected, we can just look at the session bit as that will clear automatically when the session ends.
