2015-09-08xen: Use correctly the Xen memory terminologiesJulien Grall1-2/+2
Based on include/xen/mm.h [1], Linux is mistakenly using MFN when GFN is meant, I suspect this is because the first support for Xen was for PV. This resulted in some misimplementation of helpers on ARM and confused developers about the expected behavior. For instance, with pfn_to_mfn, we expect to get an MFN based on the name. Although, if we look at the implementation on x86, it's returning a GFN. For clarity and avoid new confusion, replace any reference to mfn with gfn in any helpers used by PV drivers. The x86 code will still keep some reference of pfn_to_mfn which may be used by all kind of guests No changes as been made in the hypercall field, even though they may be invalid, in order to keep the same as the defintion in xen repo. Note that page_to_mfn has been renamed to xen_page_to_gfn to avoid a name to close to the KVM function gfn_to_page. Take also the opportunity to simplify simple construction such as pfn_to_mfn(page_to_pfn(page)) into xen_page_to_gfn. More complex clean up will come in follow-up patches.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There are little changes in core part, but lots of development are found in drivers, especially ASoC. The diffstat shows regmap-related changes for a slight API additions / changes, and that's all. Looking at the code size statistics, the most significant addition is for Intel Skylake. (Note that SKL support is still underway, the codec driver is missing.) Also STI controller driver is a major addition as well as a few new codec drivers. In HD-audio side, there are fewer changes than the past. The noticeable change is the support of ELD notification from i915 graphics driver. Thus this pull request carries a few changes in drm/i915. Other than that, USB-audio got a rewrite of runtime PM code. It was initiated by lockdep warning, but resulted in a good cleanup in the end. Below are the highlights: Common: - Factoring out of AC'97 reset code from ASoC into the core helper - A few regmap API extensions (in case it's not pulled yet) ASoC: - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek RT298 and ST STI controllers - Machine drivers for Rockchip systems with MAX98090 and RT5645 and RT5650 - Initial driver support for Intel Skylake devices - Lots of rsnd cleanup and enhancements - A few DAPM fixes and cleanups - A large number of cleanups in various drivers (conversion and standardized to regmap, component) mostly by Lars-Peter and Axel HD-audio: - Extended HD-audio core for Intel Skylake controller support - Quirks for Dell headsets, Alienware 15 - Clean up of pin-based quirk tables for Realtek codecs - ELD notifier implenetation for Intel HDMI/DP USB-audio: - Refactor runtime PM code to make lockdep happier" * tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (411 commits) drm/i915: Add locks around audio component bind/unbind drm/i915: Drop port_mst_index parameter from pin/eld callback ALSA: hda - Fix missing inline for dummy snd_hdac_set_codec_wakeup() ALSA: hda - Wake the codec up on pin/ELD notify events ALSA: hda - allow codecs to access the i915 pin/ELD callback drm/i915: Call audio pin/ELD notify function drm/i915: Add audio pin sense / ELD callback ASoC: zx296702-i2s: Fix resource leak when unload module ASoC: sti_uniperif: Ensure component is unregistered when unload module ASoC: au1x: psc-i2s: Convert to use devm_ioremap_resource ASoC: sh: dma-sh7760: Convert to devm_snd_soc_register_platform ASoC: spear_pcm: Use devm_snd_dmaengine_pcm_register to fix resource leak ALSA: fireworks/bebob/dice/oxfw: fix substreams counting at vmalloc failure ASoC: Clean up docbook warnings ASoC: txx9: Convert to devm_snd_soc_register_platform ASoC: pxa: Convert to devm_snd_soc_register_platform ASoC: nuc900: Convert to devm_snd_soc_register_platform ASoC: blackfin: Convert to devm_snd_soc_register_platform ASoC: au1x: Convert to devm_snd_soc_register_platform ASoC: qcom: Constify asoc_qcom_lpass_cpu_dai_ops ...

2015-09-03MIPS: Remove all the uses of custom gpio.hAlban Bedel1-0/+1
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

Bit 2 of the mode byte has dual meaning: it can disable reporting of gestures when touchpad works in Relative mode or normal Absolute mode, or it can enable so called Extended W-Mode when touchpad uses enhanced Absolute mode (W-mode). The extended W-Mode confuses our driver and causes missing button presses on some Thinkpads (x250, T450s), so let's make sure we do not enable it. Also, according to the spec W mode "... bit is defined only in Absolute mode on pads whose capExtended capability bit is set. In Relative mode and in TouchPads without this capability, the bit is reserved and should be left at 0.", so let's make sure we respect this requirement as well.

Convert the ac97_bus from legacy suspend/resume callbacks to dev_pm_ops. Since there isn't anything special to do at the bus level the bus driver does not have to implement any callbacks. The device driver core will automatically pick up and execute the device's PM ops. As there is only a single AC'97 driver implementing suspend and resume, update both the core and driver at the same time to avoid unnecessary code churn. While we are at it also drop the ifdefs around the suspend/resume functions to increase compile test coverage.

The ChromeOS EC keyboard driver config depends on CROS_EC_PROTO but MFD_CROS_EC selects CROS_EC_PROTO instead. Mixing select and depends on is bad practice as it may lead to circular Kconfig dependencies. Since the platform device that is matched with the keyboard driver is registered by the ChromeOS EC mfd driver, KEYBOARD_CROS_EC really should depend on MFD_CROS_EC. And because this config option selects CROS_EC_PROTO, that dependency is met as well. So make the driver to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/soc The i.MX SoC changes for 4.3: - Add i.MX6 Ultralite SoC support, which is the newest addition to i.MX6 family. It integrates a single Cortex-A7 core and a power management module that reduces the complexity of external power supply and simplifies power sequencing. - Change SNVS RTC driver to use syscon interface for register access, and add SNVS power key driver support. - Add a second clock for mxc rtc driver, and support device tree probe for the driver. - Add FEC MAC reference clock and phy fixup initialization for i.MX6UL platform. * tag 'imx-soc-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: rtc: snvs: select option REGMAP_MMIO ARM: imx6ul: add fec MAC refrence clock and phy fixup init ARM: imx6ul: add fec bits to GPR syscon definition rtc: mxc: add support of device tree dt-binding: document the binding for mxc rtc rtc: mxc: use a second rtc clock input: snvs_pwrkey: use "wakeup-source" as deivce tree property name Document: devicetree: input: imx: i.mx snvs power device tree bindings input: keyboard: imx: add snvs power key driver Document: dt: fsl: snvs: change support syscon rtc: snvs: use syscon to access register ARM: imx: add low-level debug support for i.mx6ul ARM: imx: add i.mx6ul msl support Signed-off-by: Olof Johansson <olof@lixom.net>

2015-08-07Input: elan_i2c - enable asynchronous probingDmitry Torokhov1-0/+1
It takes a bit of time to go through controller power up sequence and initialization. To not stall the overall boot progress let's probe the controller asynchronously, given that userspace is usually prepared for hot-plugging of input devices and thus does not rely on particular ordering.

If the device is in idle mode and is in the middle of a scan it may not have a chance to react to the reset and then IAP commands within required time interval and firmware update may fail. Let's bring the device out of idle mode before attempting to reset it so that the scan period is smaller and thus it can react to the command quicker.

This indicates the device coordinates should be directly mapped to screen. This is valid since scaling/flipping/rotation should be done by configuring the MXT device. It also flags to Android using INPUT_PROP_DIRECT that the device should be treated as a touch screen by default, and removes the necessity for a default IDC file.
