2016-02-12dt/bindings: add documentation on standard property unit suffixesRob Herring1-0/+39
A common review comment is to add units to DT property names. The naming convention is inconsistent unfortunately although there are clear majorities in use already. This makes it hard to remember the exact name preferred, so I'm documenting this to provide an easy point of reference.

Starting with the SAMA5D2, there is a new revision of the Atmel PMECC controller that can correct 32 bits in each sector. This controller is not 100% compatible with the previous revision that corrected a maximum of 24 bits by sector, as some register addresses overlap. Using information from the device tree, we can configure the driver to work with both versions.

This driver allows an I2C bus to switch between multiple masters. This is not hot-switching because connected I2C slaves will be re-instantiated. It is meant to select the best I2C core at runtime once the task is known. Example: Prefer i2c-gpio over another I2C core because of HW errata affecting your use case.

2016-02-12dma-buf: Add ioctls to allow userspace to flushDaniel Vetter1-1/+20
The userspace might need some sort of cache coherency management e.g. when CPU and GPU domains are being accessed through dma-buf at the same time. To circumvent this problem there are begin/end coherency markers, that forward directly to existing dma-buf device drivers vfunc hooks. Userspace can make use of those markers through the DMA_BUF_IOCTL_SYNC ioctl. The sequence would be used like following: - mmap dma-buf fd - for each drawing/upload cycle in CPU 1. SYNC_START ioctl, 2. read/write to mmap area 3. SYNC_END ioctl. This can be repeated as often as you want (with the new data being consumed by the GPU or say scanout device) - munmap once you don't need the buffer any more v2 (Tiago): Fix header file type names (u64 -> __u64) v3 (Tiago): Add documentation. Use enum dma_buf_sync_flags to the begin/end dma-buf functions. Check for overflows in start/length. v4 (Tiago): use 2d regions for sync. v5 (Tiago): forget about 2d regions (v4); use _IOW in DMA_BUF_IOCTL_SYNC and remove range information from struct dma_buf_sync. v6 (Tiago): use __u64 structured padded flags instead enum. Adjust documentation about the recommendation on using sync ioctls. v7 (Tiago): Alex' nit on flags definition and being even more wording in the doc about sync usage. v9 (Tiago): remove useless is_dma_buf_file check. Fix sync.flags conditionals and its mask order check. Add <linux/types.h> include in dma-buf.h.

2016-02-12btrfs: Introduce new mount option usebackuproot to replace recoveryQu Wenruo1-3/+8
Current "recovery" mount option will only try to use backup root. However the word "recovery" is too generic and may be confusing for some users. Here introduce a new and more specific mount option, "usebackuproot" to replace "recovery" mount option. "Recovery" will be kept for compatibility reason, but will be deprecated. Also, since "usebackuproot" will only affect mount behavior and after open_ctree() it has nothing to do with the filesystem, so clear the flag after mount succeeded. This provides the basis for later unified "norecovery" mount option.

2016-02-11ARM: 8506/1: common: DMA-mapping: add DMA_ATTR_ALLOC_SINGLE_PAGES attributeDoug Anderson1-0/+26
This patch adds the DMA_ATTR_ALLOC_SINGLE_PAGES attribute to the DMA-mapping subsystem. This attribute can be used as a hint to the DMA-mapping subsystem that it's likely not worth it to try to allocate large pages behind the scenes. Large pages are likely to make an IOMMU TLB work more efficiently but may not be worth it. See the Documentation contained in this patch for more details about this attribute and when to use it. Note that the name of the hint (DMA_ATTR_ALLOC_SINGLE_PAGES) is loosely based on the name MADV_NOHUGEPAGE. Just as there is MADV_NOHUGEPAGE vs. MADV_HUGEPAGE we could also add an "opposite" attribute to DMA_ATTR_ALLOC_SINGLE_PAGES. Without having the "opposite" attribute the lack of DMA_ATTR_ALLOC_SINGLE_PAGES means "use your best judgement about whether to use small pages or large pages".

"rm -rf" is bricking some peoples' laptops because of variables being used to store non-reinitializable firmware driver data that's required to POST the hardware. These are 100% bugs, and they need to be fixed, but in the mean time it shouldn't be easy to *accidentally* brick machines.

2016-02-09devicetree: update documentation for fw_cfg ARM bindingsGabriel Somlo1-36/+2
Remove fw_cfg hardware interface details from Documentation/devicetree/bindings/arm/fw-cfg.txt, and replace them with a pointer to the authoritative documentation in the QEMU source tree.

2016-02-09firmware: create directory hierarchy for sysfs fw_cfg entriesGabriel Somlo1-0/+42
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.

2016-02-09firmware: introduce sysfs driver for QEMU's fw_cfg deviceGabriel Somlo1-0/+58
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.

2016-02-09misc: mic: MIC host and card driver changes to enable VOPSudeep Dutt3-26/+32
This patch modifies the MIC host and card drivers to start using the VOP driver. The MIC host and card drivers now implement the VOP bus operations and register a VOP device on the VOP bus. MIC driver stack documentation is also updated to include the new VOP driver.
