Jonathan writes: First round of new device support, features and cleanups for IIO in the 4.11 cycle. It's shaping to be another fairly busy cycle. Lots more on the way! New device support * ads7950 - new driver supporting ads7950, ads7951, ads7952, ads7953, ads7954, ads7955, ads7956, ads7957, ads7958, ads7959, ads7960, and ads7961 ADCs. * cm3605 - New driver for this light sensor and proximity sensor which is an analog part with some additional digital controls. * hx711 - New driver. Core new stuff * Gravity sensor type. This is a processed datastream in which the device will try to work out which way is down. * Split the buffer.h file into two parts. One provides the interface to 'use' a buffer, the second provides the internals of the buffer functionality as needed by implementations of buffers. - Move documentation inline so as to allow use of private: tag when generating documentation. - Add some utility functions for the few things that are directly done with the buffers. - Stop exporting functions that no-one uses outside of the core code. - Push docs down by the code in the c file where they should have always been. - Fix typo in kernel-doc for buffer. - push down some includes that were previously happening implicitly. - stop enabling the timestamp of the dummy device. Features and cleanups * ad5592r - ACPI support * ad5593r -ACPI support. * ad5933 - Fix a false comment about size of a particular register. * ad7150 - replace S_IRUGO | S_IWUSR with 0644. I'm not that keen on these patches in general, but as it was nicely presented I took this one anyway. As a general rule will only take these as part of a larger driver cleanup. - don't eat an error but rather reutnr it in the write_event_config callback. * ad7606 - replace non standard range attibute with _scale * ade7753 - use usleep_range for short sleeps * ade7754 - use usleep_range for short sleeps * ade7758 - use usleep_range for short sleeps * ade7759 - use usleep_range for short sleeps * ade7854 - use usleep_range for short sleeps * adis16201 - fix description * adis16203 - fix description - fix copyright year * adis16209 - fix description * adt7316 - Add braces to arms of if else statement (for consistency) - Alignment fixes. * axp288 - Fix up an issue with accidental overwrites of data. * bmi160 - add deivce tables for i2c and spi to support correctly identifying the full dt name (including manufacturer). - device tree binding. * bmp280 - use usleep_range for short sleeps. * cm3232 - return error from cm3232_reg_init rather than eating it if the last write fails. * dummy driver - remove a semicolor found at end of a function defintition. * exynos-adc - use usleep_range for short sleeps. * hid-sensor (accel) - Add timestamp support. The hardware can provide timestamps so lets support them. If not fall back to timestamps estimated in kernel. * hid-sensor (light) - Add a duplicate ID for the light channels so as to keep existing interface whilst also using the more standard IIO interface. * hts221 - acpi probing * imx25-gcq - Add a macro call to allow this driver to be automatically loaded. * isl29028 - reorganise code to avoid deep nesting of if statements. - move chip test and default regs into a function suitable or sharing with power management code. - tidy up some code alignment. * lidar-lite-v3 - introduce compatible strings that make it clear Garmin have consideral friends. * mma8452 - avoid returning signed value when unsigned is appropriate * spmi-vadc - Update function for generic voltage conversion to take into account that different channels on this device should be handled differently. - Rework code to allow per channel voltage scaling and support the standard options for this hardware. - Fixup three minor issues with the above patches for this part. These all effect test builds rather than the native builds for the part, but good to clean them up anyway. * st_sensors - support device matching from the ACPI DST tables. - acpi based probing for accelerometers - acpi based probing for pressure sensors - Allow pressure sensors to read negative values. - Export sampling frequency for lps25h and lps331ap. - Add support for the old DT bindings from the period when these deivces were often supported through windows. Docs fixup: * typo in sysfs-bus-iio

2017-01-10iio: accel: st_accel: handle deprecated bindingsLinus Walleij2-1/+3
The earlier deployed LIS3LV02DL driver had already defined a few DT bindings that need to be supported by the new more generic driver and listed as compatible but deprecated bindings in the documentation. After this we can start to activate the new driver with the old systems where applicable. As part of this enablement: make us depend on the old drivers not being in use so we don't get a kernel with two competing drivers.

2016-12-26ACPI / sysfs: Provide quirk mechanism to prevent GPE floodingLv Zheng1-0/+10
Sometimes, the users may require a quirk to be provided from ACPI subsystem core to prevent a GPE from flooding. Normally, if a GPE cannot be dispatched, ACPICA core automatically prevents the GPE from firing. But there are cases the GPE is dispatched by _Lxx/_Exx provided via AML table, and OSPM is lacking of the knowledge to get _Lxx/_Exx correctly executed to handle the GPE, thus the GPE flooding may still occur. The existing quirk mechanism can be enabled/disabled using the following commands to prevent such kind of GPE flooding during runtime: # echo mask > /sys/firmware/acpi/interrupts/gpe00 # echo unmask > /sys/firmware/acpi/interrupts/gpe00 To avoid GPE flooding during boot, we need a boot stage mechanism. This patch provides such a boot stage quirk mechanism to stop this kind of GPE flooding. This patch doesn't fix any feature gap but since the new feature gaps could be found in the future endlessly, and can disappear if the feature gaps are filled, providing a boot parameter rather than a DMI table should suffice.

Pull x86 cache allocation interface from Thomas Gleixner: "This provides support for Intel's Cache Allocation Technology, a cache partitioning mechanism. The interface is odd, but the hardware interface of that CAT stuff is odd as well. We tried hard to come up with an abstraction, but that only allows rather simple partitioning, but no way of sharing and dealing with the per package nature of this mechanism. In the end we decided to expose the allocation bitmaps directly so all combinations of the hardware can be utilized. There are two ways of associating a cache partition: - Task A task can be added to a resource group. It uses the cache partition associated to the group. - CPU All tasks which are not member of a resource group use the group to which the CPU they are running on is associated with. That allows for simple CPU based partitioning schemes. The main expected user sare: - Virtualization so a VM can only trash only the associated part of the cash w/o disturbing others - Real-Time systems to seperate RT and general workloads. - Latency sensitive enterprise workloads - In theory this also can be used to protect against cache side channel attacks" [ Intel RDT is "Resource Director Technology". The interface really is rather odd and very specific, which delayed this pull request while I was thinking about it. The pull request itself came in early during the merge window, I just delayed it until things had calmed down and I had more time. But people tell me they'll use this, and the good news is that it is _so_ specific that it's rather independent of anything else, and no user is going to depend on the interface since it's pretty rare.

The patches regarding eee-broken-modes was merged before all people involved could find an agreement on the best way to move forward. While we agreed on having a DT property to mark particular modes as broken, the value used for eee-broken-modes mapped the phy register in very direct way. Because of this, the concern is that it could be used to implement configuration policies instead of describing a broken HW. In the end, having a boolean property for each mode seems to be preferred over one bit field value mapping the register (too) directly.

2016-12-20ima: define a canonical binary_runtime_measurements list formatMimi Zohar1-0/+4
The IMA binary_runtime_measurements list is currently in platform native format. To allow restoring a measurement list carried across kexec with a different endianness than the targeted kernel, this patch defines little-endian as the canonical format. For big endian systems wanting to save/restore the measurement list from a system with a different endianness, a new boot command line parameter named "ima_canonical_fmt" is defined. Considerations: use of the "ima_canonical_fmt" boot command line option will break existing userspace applications on big endian systems expecting the binary_runtime_measurements list to be in platform native format.
