2014-07-29tpm: Provide a generic means to override the chip returned timeoutsJason Gunthorpe1-0/+3
Some Atmel TPMs provide completely wrong timeouts from their TPM_CAP_PROP_TIS_TIMEOUT query. This patch detects that and returns new correct values via a DID/VID table in the TIS driver.

2014-07-29net: remove deprecated syststamp timestampWillem de Bruijn1-13/+1
The SO_TIMESTAMPING API defines three types of timestamps: software, hardware in raw format (hwtstamp) and hardware converted to system format (syststamp). The last has been deprecated in favor of combining hwtstamp with a PTP clock driver. There are no active users in the kernel. The option was device driver dependent. If set, but without hardware support, the correct behavior is to return zero in the relevant field in the SCM_TIMESTAMPING ancillary message. Without device drivers implementing the option, this field is effectively always zero. Remove the internal plumbing to dissuage new drivers from implementing the feature. Keep the SOF_TIMESTAMPING_SYS_HARDWARE flag, however, to avoid breaking existing applications that request the timestamp. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

2014-07-29ARM: imx: Add the secondary request into the structure for imx-sdmaNicolin Chen1-0/+1
SDMA supports device to device (per_2_per) scripts to handle DMA transfering between two peripheral devices. The per_2_per script, however, needs two dma requests from two sides while the current structure only defined one request. So this patch just simply adds the secondary request so as to let SDMA and its user to add its implementation later. [ Both change in the SDMA driver and its users like Freescale ASRC ASoC driver should be taken along with this change in order to truly support per_2_per sciprts. However, we here make an expediency by adding this first so that we can add either side later since this patch won't break any function and meanwhile it can make merge window more smoothly: we don't need to apply the change inside dmaengine branch via ASoC tree any more. -- Nicolin ] Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com> Acked-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-07-28gpio: add flags argument to gpiod_get*() functionsAlexandre Courbot1-16/+65
The huge majority of GPIOs have their direction and initial value set right after being obtained by one of the gpiod_get() functions. The integer GPIO API had gpio_request_one() that took a convenience flags parameter allowing to specify an direction and value applied to the returned GPIO. This feature greatly simplifies client code and ensures errors are always handled properly. A similar feature has been requested for the gpiod API. Since setting the direction of a GPIO is so often the very next action done after obtaining its descriptor, we prefer to extend the existing functions instead of introducing new functions that would raise the number of gpiod getters to 16 (!). The drawback of this approach is that all gpiod clients need to be updated. To limit the pain, temporary macros are introduced that allow gpiod_get*() to be called with or without the extra flags argument. They will be removed once all consumer code has been updated.

2014-07-25Input: wacom - switch from an USB driver to a HID driverBenjamin Tissoires1-0/+5
All USB Wacom tablets are actually HID devices. For historical reasons, they are handled as plain USB devices. The current code makes more and more reference to the HID subsystem like implementing its own HID report descriptor parser to handle new devices. From the user point of view, we can transparently switch from this state to a driver handled in the HID subsystem and clean up a lot of USB specific code in the wacom.ko driver. The other benefit once the USB dependecies have been removed is that we can use a tool like uhid to make regression tests and allow further cleanup or new implementations without risking breaking current behaviors. To match the current handling of devices in wacom_wac.c, we rely on the hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the device is plain HID. There is thus a one to one matching between the list of supported devices before and after the switch from USB to HID.

Add helper functions that allow regulator consumers to obtain low-level details about the regulator hardware, like the voltage selector register address and such. These details can be useful when configuring hardware or firmware that want to do low-level access to regulators, with no involvement from the kernel. The use-case for Tegra is a voltage-controlled oscillator clocksource which has control logic to change the supply voltage via I2C to achieve a desired output clock rate.

2014-07-25mfd: max77686: Add Maxim 77802 PMIC supportJavier Martinez Canillas2-2/+263
Maxim MAX77802 is a power management chip that contains 10 high efficiency Buck regulators, 32 Low-dropout (LDO) regulators used to power up application processors and peripherals, a 2-channel 32kHz clock outputs, a Real-Time-Clock (RTC) and a I2C interface to program the individual regulators, clocks outputs and the RTC. This patch adds support for MAX77802 to the MAX77686 driver and is based on a driver added to the Chrome OS kernel 3.8 by Simon Glass.

2014-07-25arm64: gicv3: Allow GICv3 compilation with older binutilsCatalin Marinas1-20/+22
GICv3 introduces new system registers accessible with the full msr/mrs syntax (e.g. mrs x0, Sop0_op1_CRm_CRn_op2). However, only recent binutils understand the new syntax. This patch introduces msr_s/mrs_s assembly macros which generate the equivalent instructions above and converts the existing GICv3 code (both drivers/irqchip/ and arch/arm64/kernel/).
