2016-03-05[media] media: rc: nuvoton: switch attribute wakeup_data to textHeiner Kallweit
Switch attribute wakeup_data from binary to a text attribute. This makes it easier to handle in userspace and allows to use the output of tools like mode2 almost as is to set a wakeup sequence. Changing to a text format and values in microseconds also makes the userspace interface independent of the setting of SAMPLE_PERIOD in the driver. In addition document the new sysfs attribute in Documentation/ABI/testing/sysfs-class-rc-nuvoton.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Third set of IIO new device support, features and cleanups for the 4.6 cycle. Good to see several new contributors in this set - and more generally a number of new 'faces' over this whole cycle. Staging movements * hmc5843 - out of staging. * periodic RTC trigger - driver dropped. This is an ancient driver (brings back some memories ;) that was always somewhat of a bodge. Originally there was a driver that never went into mainline that supported large numbers of periodict timers on the PXA270 via this route. Discussions to have a generic periodic timer subsystem never went anywhere. At the time RTC periodic interrupts were real - now they are emulated using high resolution timers so with the HRT driver this has become pointless. New device support * mpu6050 driver - Add support for the mpu6500. * TI tpl0102 potentiometer - new driver. * Vybrid SoC DAC - new driver. The ADC on this SoC has been supported for a while, this adds a separate driver for the DAC. New Features * hmc5844 - Attributes to configure the bias current (typically part of a self test) This could be done before via a somewhat obscure custom interface. This at least makes it easy to tell what is going on. - Document all custom attributes. * mpu6050 - Add support for calibration offset control and readback. * ms5611 - power regulator support. This is always one that gets added the first time someone has a board that needs it. Here it was needed, hence it was added. Cleanups / minor fixes * tree wide - clean up all the myriad different return values in response to a failure of i2c_check_functionality. After discussions everyone seemed happy wiht -EOPNOTSUPP which seems to describe the situation well. I encouraged a tree wide cleanup to set a good example in future for this. * core - Typos in the iio_event_spec documentation in iio.h * afe4403 - select REGMAP_SPI to avoid dependency issues - mark suspend/resume as __maybe_unused to avoid warnings * afe4404 - mark suspend/resume as __maybe_unused to avoid warnings * atlas-ph-sensor - switch the regmap cache type from linear to rbtree to gain reading of registers on initial startup. It's not immediately obvious, but regmap flat is meant for high performances cases so doesn't read these registers. - use regmap_bulk_read in one case where it was using i2c_smbus_read_i2c_block_data directly (unlike everything else that was through regmap). * ina2xx - stype cleanups (lots of them!) * isl29018 - Get the struct device back from regmap rather than storing another copy of it in the private data. This cleanup makes sense in a number of other drivers so patches may well follow. * mpu6050 - style cleanups (lots of them!) - improved return value handling - use usleep_range to avoid the usual issues with very short msleeps. - add some missing documentation. * ms5611 - use the probed device name for the device rather than the driver name. - select IIO_BUFFER to avoid dependency issues * palmas - drop IRQF_EARLY_RESUME as no longer needed after genirq changes.

Antonio Quartulli says: ==================== batman-adv 20160229 this is our (hopefully) latest batch of patches intended for net-next. With this patchset we finally introduce B.A.T.M.A.N. V: the latest version of our routing protocol. Technical documentation describing the protocol in more detail can be found in our wiki[1][2][3][4]. For what concerns this pull request, you can find the high level description right below. [1] https://www.open-mesh.org/projects/batman-adv/wiki/BATMAN_V [2] https://www.open-mesh.org/projects/batman-adv/wiki/OGMv2 [3] https://www.open-mesh.org/projects/batman-adv/wiki/ELP [4] https://www.open-mesh.org/projects/batman-adv/wiki/BATMAN_V_Tests ... With this patchset we finally introduce our new routing protocol: B.A.T.M.A.N. V. Its implementation started quite some years ago, but due to the big changes being introduced it took a while to be discussed, designed, worked, re-worked, tested and debugged (well, we're never done with the latest). The entire operation has basically been a team work involving all the core contributors together with other people interested in the project. The new protocol is divided into two main subcomponents, called respectively ELP and OGMv2. The former is in charge of dealing with the neighbour discovery and link quality estimation, while the latter implements the algorithm that spreads the metrics around the network and computes optimal paths. The biggest change introduced with B.A.T.M.A.N. V is the new metric: the protocol won't rely on packet loss anymore, but it will use the estimated throughput extracted directly from the wifi driver (when available) by querying cfg80211. Batman-adv will also send some unicast probing packets when an interface is not used for payload traffic to make sure that such values are current. The new protocol can be compiled-in or not like other features we have and when selected will pull in CFG80211 as dependency for the reason described above. Thanks to the big work brought up in the past by Marek Lindner, batman-adv can easily deal several protocol implementations, therefore compiling in this new version does not exclude the older. This means that the user is offered the option to choose the protocol when creating the mesh interface (default is the old one to keep backward compatibility). Along with the protocol there are some sysfs knobs that are introduced to fine tune some of its behaviours, but users are recommended to keep the default values unless they know what they are doing. The last patch is about advertising our own patchwork platform (thanks to Sven Eckelmann for having set that up!) in the MAINTAINERS file. ==================== Signed-off-by: David S.

This attribute is exported to user space to disable the link throughput auto-detection by setting a fixed value. The throughput override value is used when batman-adv is computing the link throughput towards a neighbour. If the value is set to 0 then batman-adv will try to detect the throughput by itself.

2016-02-29batman-adv: ELP - adding sysfs parameter for elp intervalLinus Luessing
This parameter can be set individually on each interface and allows the configuration of the elp interval for the link quality measurements during runtime. Usually it is desirable to set it to a higher (= slower) value on interfaces which have a more static characteristic (e.g. wired interfaces) or very dense neighbourhoods to reduce overhead.

2016-02-21ima: support for kexec image and initramfsMimi Zohar
Add IMA policy support for measuring/appraising the kexec image and initramfs. Two new IMA policy identifiers KEXEC_KERNEL_CHECK and KEXEC_INITRAMFS_CHECK are defined. Example policy rules: measure func=KEXEC_KERNEL_CHECK appraise func=KEXEC_KERNEL_CHECK appraise_type=imasig measure func=KEXEC_INITRAMFS_CHECK appraise func=KEXEC_INITRAMFS_CHECK appraise_type=imasig Moving the enumeration to the vfs layer simplified the patches, allowing the IMA changes, for the most part, to be separated from the other changes. Unfortunately, passing either a kernel_read_file_id or a ima_hooks enumeration within IMA is messy. Option 1: duplicate kernel_read_file enumeration in ima_hooks enum kernel_read_file_id { ... READING_KEXEC_IMAGE, READING_KEXEC_INITRAMFS, READING_MAX_ID enum ima_hooks { ... KEXEC_KERNEL_CHECK KEXEC_INITRAMFS_CHECK Option 2: define ima_hooks as extension of kernel_read_file eg: enum ima_hooks { FILE_CHECK = READING_MAX_ID, MMAP_CHECK, In order to pass both kernel_read_file_id and ima_hooks values, we would need to specify a struct containing a union. struct caller_id { union { enum ima_hooks func_id; enum kernel_read_file_id read_id; }; }; Option 3: incorportate the ima_hooks enumeration into kernel_read_file_id, perhaps changing the enumeration name. For now, duplicate the new READING_KEXEC_IMAGE/INITRAMFS in the ima_hooks. Changelog v4: - replaced switch statement with a kernel_read_file_id to an ima_hooks id mapping array - Dmitry - renamed ima_hook tokens KEXEC_CHECK and INITRAMFS_CHECK to KEXEC_KERNEL_CHECK and KEXEC_INITRAMFS_CHECK respectively - Dave Young Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com> Acked-by: Petko Manolov <petkan@mip-labs.com> Acked-by: Dmitry Kasatkin <dmitry.kasatkin@huawei.com> Cc: Dave Young <dyoung@redhat.com>

2016-02-09firmware: create directory hierarchy for sysfs fw_cfg entriesGabriel Somlo
Each fw_cfg entry of type "file" has an associated 56-char, nul-terminated ASCII string which represents its name. While the fw_cfg device doesn't itself impose any specific naming convention, QEMU developers have traditionally used path name semantics (i.e. "etc/acpi/rsdp") to descriptively name the various fw_cfg "blobs" passed into the guest. This patch attempts, on a best effort basis, to create a directory hierarchy representing the content of fw_cfg file names, under /sys/firmware/qemu_fw_cfg/by_name. Upon successful creation of all directories representing the "dirname" portion of a fw_cfg file, a symlink will be created to represent the "basename", pointing at the appropriate /sys/firmware/qemu_fw_cfg/by_key entry. If a file name is not suitable for this procedure (e.g., if its basename or dirname components collide with an already existing dirname component or basename, respectively) the corresponding fw_cfg blob is skipped and will remain available in sysfs only by its selector key value.

Make fw_cfg entries of type "file" available via sysfs. Entries are listed under /sys/firmware/qemu_fw_cfg/by_key, in folders named after each entry's selector key. Filename, selector value, and size read-only attributes are included for each entry. Also, a "raw" attribute allows retrieval of the full binary content of each entry. The fw_cfg device can be instantiated automatically from ACPI or the Device Tree, or manually by using a kernel module (or command line) parameter, with a syntax outlined in the documentation file.

The driver should be a lot more stable on v4.5 then ever before. Our good old dwc3 got a few cleanups and misc fixes and also added support to Xilinx's integration of this IP. Yoshihiro Shimoda gives us support for a new USB3 peripheral controller from Renesas. Other than these, the usual misc fixes all over the place.
2015-12-23IB/cma: Add configfs for rdma_cmMatan Barak
Users would like to control the behaviour of rdma_cm. For example, old applications which don't set the required RoCE gid type could be executed on RoCE V2 network types. In order to support this configuration, we implement a configfs for rdma_cm. In order to use the configfs, one needs to mount it and mkdir <IB device name> inside rdma_cm directory. The patch adds support for a single configuration file, default_roce_mode. The mode can either be "IB/RoCE v1" or "RoCE v2".

2015-12-23IB/core: Add gid attributes to sysfsMatan Barak

Since the same GID could have different types or associated net devices, users should have the ability to query the associated GID attributes. Adding these attributes to sysfs.

2015-12-01usb: core: lpm: add sysfs node for usb3 lpm permitLu Baolu
USB3 LPM is default on in Linux kernel if both xHCI host controller and the USB devices declare to be LPM-capable. Unfortunately, some devices are known to work well with LPM disabled, but to be broken if LPM is enabled, although it declares the LPM capability. Users won't be able to use this kind of devices, until someone puts them in the kernel blacklist and gets the kernel upgraded. This patch adds a sysfs node to permit or forbit USB3 LPM U1 or U2 entry for a port. The settings apply to both before and after device enumeration. Supported values are "0" - neither u1 nor u2 permitted, "u1" - only u1 is permitted, "u2" - only u2 is permitted, "u1_u2" - both u1 and u2 are permitted. With this interface, users can use an LPM-unfriendly USB device on a released Linux kernel.
