2018-12-16iio: add IIO_MASSCONCENTRATION channel typeTomasz Duszynski
Measuring particulate matter in ug / m3 (micro-grams per cubic meter) is de facto standard. Existing air quality sensors usually follow this convention and are capable of returning measurements using this unit. IIO currently does not offer suitable channel type for this type of measurements hence this patch adds this. In addition, extra modifiers are introduced used for distinguishing between fine pm1, pm2p5 and coarse pm4, pm10 particle measurements, i.e IIO_MOD_PM1, IIO_MOD_PM25 and IIO_MOD_PM4, IIO_MOD_PM10. pmX consists of particles with aerodynamic diameter less or equal to X micrometers.

2018-12-12cpuidle: Add 'above' and 'below' idle state metricsRafael J. Wysocki
Add two new metrics for CPU idle states, "above" and "below", to count the number of times the given state had been asked for (or entered from the kernel's perspective), but the observed idle duration turned out to be too short or too long for it (respectively). These metrics help to estimate the quality of the CPU idle governor in use. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

2018-12-05thunderbolt: Export IOMMU based DMA protection support to userspaceMika Westerberg
Recent systems with Thunderbolt ports may support IOMMU natively. In practice this means that Thunderbolt connected devices are placed behind an IOMMU during the whole time it is connected (including during boot) making Thunderbolt security levels redundant. This is called Kernel DMA protection [1] by Microsoft. Some of these systems still have Thunderbolt security level set to "user" in order to support OS downgrade (the older version of the OS might not support IOMMU based DMA protection so connecting a device still relies on user approval). Export this information to userspace by introducing a new sysfs attribute (iommu_dma_protection). Based on it userspace tools can make more accurate decision whether or not authorize the connected device. In addition update Thunderbolt documentation regarding IOMMU based DMA protection.

2018-11-30net: dsa: Fix tagging attribute locationFlorian Fainelli
While introducing the DSA tagging protocol attribute, it was added to the DSA slave network devices, but those actually see untagged traffic (that is their whole purpose). Correct this mistake by putting the tagging sysfs attribute under the DSA master network device where this is the information that we need. While at it, also correct the sysfs documentation mistake that missed the "dsa/" directory component of the attribute.

2018-11-26drivers: base: Introducing software nodes to the firmware node frameworkHeikki Krogerus
Software node is a new struct fwnode_handle type that can be used to describe devices in kernel (software). It is meant to complement fwnodes representing real firmware nodes when they are incomplete (for example missing device properties) and to supply the primary fwnode when the firmware lacks hardware description for a device completely. The software node type is really meant to replace the currently used "property_set" struct fwnode_handle type. The handling of struct property_set is glued to the generic device property handling code, and it is not possible to create a struct property_set independently from the device that it is bind to. struct property_set is only created when device properties are added to already initialized struct device, and control of it is only possible from the generic property handling code. Software nodes are instead designed to be created independently from the device entries (struct device). It makes them much more flexible, as then the device meant to be bind to the node can be created at a later time, and from another location. It is also possible to bind multiple devices to a single software node if needed. The software node implementation also includes support for node hierarchy, which was the main motivation for this commit. The node hierarchy was something that was requested for the struct property_set, but it did not seem reasonable to try to extend the property_set support for that purpose. struct property_set was really meant only for device property handling like the name suggests. Support for struct property_set is not yet removed in this commit, but it will be in the following one.

The platform firmware "location" data is used to find port peer relationships. But firmware is an unreliable source, and there are real world examples of errors leading to missing or wrong peer relationships. Debugging this is currently hard. Exporting the location attribute makes it easier to spot mismatches between the firmware data and the real world.

2018-09-28usb: core: added uevent for over-currentJon Flatley
After commit 1cbd53c8cd85 ("usb: core: introduce per-port over-current counters") usb ports expose a sysfs value 'over_current_count' to user space. This value on its own is not very useful as it requires manual polling. As a solution, fire a udev event from the usb hub device that specifies the values 'OVER_CURRENT_PORT' and 'OVER_CURRENT_COUNT' that indicate the path of the usb port where the over-current event occurred and the value of 'over_current_count' in sysfs. Additionally, call sysfs_notify() so the sysfs value supports poll(). Signed-off-by: Jon Flatley <jflat@chromium.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-09-24usb: gadget: uvc: configfs: Add bFrameIndex attributesJoel Pepper
- Add bFrameIndex as a UVCG_FRAME_ATTR_RO for each frame size. - Automatically assign ascending bFrameIndex to each frame in a format. Before all "bFrameindex" attributes were set to "1" with no way to configure the gadget otherwise. This resulted in the host always negotiating for bFrameIndex 1 (i.e. the first frame size of the gadget). After the negotiation the host driver will set the user or application selected frame size, while the gadget is actually set to the first frame size. Now, when the containing format is linked into the streaming header, iterate over all child frame descriptors and assign ascending indices. The automatically assigned indices can be read from the new read only bFrameIndex configfs attribute in each frame descriptor item.

2018-09-24usb: gadget: uvc: configfs: Add bFormatIndex attributesLaurent Pinchart
The UVC format description are numbered using the descriptor's bFormatIndex field. The index is used in UVC requests, and is thus needed to handle requests in userspace. Make it dynamically discoverable by exposing it in a bFormatIndex configfs attribute of the uncompressed and mjpeg format config items. The bFormatIndex value exposed through the attribute is stored in the config item private data. However, that value is never set: the driver instead computes the bFormatIndex value when linking the stream class header in the configfs hierarchy and stores it directly in the class descriptors in a separate structure. In order to expose the value through the configfs attribute, store it in the config item private data as well. This results in a small code simplification.

2018-09-24usb: gadget: uvc: configfs: Add interface number attributesLaurent Pinchart
The video control and video streaming interface numbers are needed in the UVC gadget userspace stack to reply to UVC requests. They are hardcoded to fixed values at the moment, preventing configurations with multiple functions. To fix this, make them dynamically discoverable by userspace through read-only configfs attributes in <function>/control/bInterfaceNumber and <function>/streaming/bInterfaceNumber respectively.

2018-09-14xen/balloon: add runtime control for scrubbing ballooned out pagesMarek Marczykowski-Górecki
Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 1st round of IIO new device support, features and cleanups in the 4.20 cycle. There is a merge commit in here to pull in regmap support for repeatedly reading the same register (to read out FIFOs). Used by the adxl372 driver. This will find uses elsewhere once we tidy up various drivers that are effectively doing this and relying on not enabling regcache. New device support * Analog devices ADXL372 accelerometer - new driver for this accelerometer including fifo and and interrupt support. Follow up patches enforce trigger validation, add sampling frequency control and filter bandwidth control. A later series added i2c support to the existing SPI support. * ST lsm6dsx - rework and add support fo the LSM6DSO 6 axis mems sensor. * Linear LTC 1660 DAC - new driver supporting the LTC 1660 and LTC 1665 SPI DACs. * Microchip mcp3911 ADC. - new driver for this integrated analog front end and ADC. * Qualcomm SPMI PMIC5 adc driver - using the spmi framework, new driver and bindings for this ADC. Follow up patch adds some missing channels. Features * ad5758 - support hard reset using a gpio (if provided). * mpu6050 - Regulator support * qcom-spmi-adc5 - Sanity check the channel numbers provided by DT to make sure the driver actually knows about them. * sc27xx - give raw data for channel 20 as it's used on all known boards for the headset which needs a custom converstion function. If it turns out someone builds a board where this isn't true we will deal with it when it happens. - add ADC scale calibration. * tsl2772 - support device tree binding to set the proximity led settings. - regulator supprot. - binding for apds9930 - trivial addition as register compatible with tsl2772.
