2017-01-26pinctrl: broxton: Rename apl-pinctrl driverAndy Shevchenko

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: USB: changes for v4.11 Here's the big pull request for the Gadget API. Again the majority of changes sit in dwc2 driver. Most important changes contain a workaround for GOTGCTL being wrong, a sleep-inside-spinlock fix and the big series of cleanups on dwc2. One important thing on dwc3 is that we don't anymore need gadget drivers to cope with unaligned OUT transfers for us. We have support for appending one extra chained TRB to align transfer ourselves. Apart from these, the usual set of typos, non-critical fixes, etc.

2017-01-26pinctrl / gpio: Introduce .set_config() callback for GPIO chipsMika Westerberg
Currently we already have two pin configuration related callbacks available for GPIO chips .set_single_ended() and .set_debounce(). In future we expect to have even more, which does not scale well if we need to add yet another callback to the GPIO chip structure for each possible configuration parameter. Better solution is to reuse what we already have available in the generic pinconf. To support this, we introduce a new .set_config() callback for GPIO chips. The callback takes a single packed pin configuration value as parameter. This can then be extended easily beyond what is currently supported by just adding new types to the generic pinconf enum. If the GPIO driver is backed up by a pinctrl driver the GPIO driver can just assign gpiochip_generic_config() (introduced in this patch) to .set_config and that will take care configuration requests are directed to the pinctrl driver. We then convert the existing drivers over .set_config() and finally remove the .set_single_ended() and .set_debounce() callbacks.

2017-01-26pinctrl: Allow configuration of pins from gpiolib based driversMika Westerberg
When a GPIO driver is backed by a pinctrl driver the GPIO driver sometimes needs to call the pinctrl driver to configure certain things, like whether the pin is used as input or output. In addition to this there are other configurations applicable to GPIOs such as setting debounce time of the GPIO. To support this we introduce a new function pinctrl_gpio_set_config() that can be used by gpiolib based driver to pass configuration requests to the backing pinctrl driver.

2017-01-26pinctrl: Widen the generic pinconf argument from 16 to 24 bitsMika Westerberg
The current pinconf packed format allows only 16-bit argument limiting the maximum value 65535. For most types this is enough. However, debounce time can be in range of hundreths of milliseconds in case of mechanical switches so we cannot represent the worst case using the current format. In order to support larger values change the packed format so that the lower 8 bits are used as type which leaves 24 bits for the argument. This allows representing values up to 16777215 and debounce times up to 16 seconds. We also convert the existing users to use 32-bit integer when extracting argument from the packed configuration value.

2017-01-26gpio: aspeed: Add banks Y, Z, AA, AB and ACAndrew Jeffery
This is less straight-forward than one would hope, as some banks only have 4 pins rather than 8, others are output only, yet more (W and X, already supported) are input-only, and in the case of the g4 SoC bank AC doesn't exist. Add some structs to describe the varying properties of different banks and integrate mechanisms to deny requests for unsupported configurations.

2017-01-26pinctrl: aspeed: g4: Fix mux configuration for GPIOs AA[4-7], AB[0-7]Andrew Jeffery
Incorrect video output configuration bits were being tested on pins in GPIO banks AA and AB for the ROM{8,16} mux functions. The ROM{8,16} functions are the highest priority for the relevant pins and also the default function, so we require the relevant video output configuration be disabled to mux GPIO functionality. As the wrong bits were being tested a GPIO export would succeed but leave the pin in an unresponsive state (i.e. value updates were ignored). This misbehaviour was discovered as part of extending the GPIO controller's support to cover banks Y, Z, AA, AB and AC (AC in the case of the g5 SoC).

2017-01-26pinctrl: qcom: Use raw spinlock variantsJulia Cartwright
The MSM pinctrl driver currently implements an irq_chip for handling GPIO interrupts; due to how irq_chip handling is done, it's necessary for the irq_chip methods to be invoked from hardirq context, even on a a real-time kernel. Because the spinlock_t type becomes a "sleeping" spinlock w/ RT kernels, it is not suitable to be used with irq_chips. A quick audit of the operations under the lock reveal that they do only minimal, bounded work, and are therefore safe to do under a raw spinlock. On real-time kernels, this fixes an OOPs which looks like the following, as reported by Brian Wrenn: kernel BUG at kernel/locking/rtmutex.c:1014!

2017-01-25net: phy: broadcom: use auxctl reading helper in BCM54612E codeRafał Miłecki
Starting with commit 5b4e29005123 ("net: phy: broadcom: add bcm54xx_auxctl_read") we have a reading helper so use it and avoid code duplication. It also means we don't need MII_BCM54XX_AUXCTL_SHDWSEL_MISC define as it's the same as MII_BCM54XX_AUXCTL_SHDWSEL_MISC just for reading needs (same value shifted by 12 bits).

2017-01-25virtio_net: reject XDP programs using header adjustmentJakub Kicinski
commit 17bedab27231 ("bpf: xdp: Allow head adjustment in XDP prog") added a new XDP helper to prepend and remove data from a frame. Make virtio_net reject programs making use of this helper until proper support is added.

2017-01-25virtio_net: use dev_kfree_skb for small buffer XDP receiveJohn Fastabend
In the small buffer case during driver unload we currently use put_page instead of dev_kfree_skb. Resolve this by adding a check for virtnet mode when checking XDP queue type. Also name the function so that the code reads correctly to match the additional check.

Schedule the napi after napi_enable() for rx, if it is necessary. If the rx is completed when napi is disabled, the sheduling of napi would be lost. Then, no one handles the rx packet until next napi is scheduled. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
