Merge tag 'extcon-next-for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next Chanwoo writes: Update extcon for 3.13 This patchset modify extcon core to remove unnecessary allocation sequence for 'dev' instance and change extcon_dev_register() interface. extcon-gpio use gpiolib API to get debounce time and include small fix of extcon core/device driver. Detailed description for patchset: 1. Modify extcon core driver - The extcon-gpio driver use gpio_set_debounce() API provided from gpiolib if gpio driver for SoC support gpio_set_debounce() function and support 'gpio_ activ_low' filed to check whether gpio active state is 1(high) or 0(low). - Change field type of 'dev' in structure extcon_dev and remove the sequence of allocating memory of 'struct dev' on extcon_dev_register() function because extcon device must need 'struct device. - Change extcon_dev_register() prototype to simplify it and remove unnecessary parameter as below: 2. Fix coding style and typo - extcon core : Fix indentation coding style and remove unnecessary casting - extcon-max8997 : Fix checkpatch warning - extcon-max77693 : Fix checkpatch warning - extcon-arizona : Fix typo of comment and modify minor issue - extcon-palmas : Use dev_get_platdata() 3. Modify extcon-arizona driver - Modify minor issue about micbias and comparision statement

This patch remove extcon_dev_register()'s second parameter which means the pointer of parent device to simplify prototype of this function. So, if extcon device has the parent device, it should set the pointer of parent device to edev.dev.parent in extcon device driver instead of in extcon_dev_register().

We want the trig_sts bits to be cleared in all cases where we consider the jack detection interrupt to have been handled. Specifically, if a duplicate detection event was suppressed these bits were not cleared causing the CODEC to not enter a low power state. This patch clears the bits on the duplicate detection code path. Reported-by:

This patch introduces a sample user space daemon which implements the virtio device backends on the host. The daemon creates/removes/configures virtio device backends by communicating with the Intel MIC Host Driver. The virtio devices currently supported are virtio net, virtio console and virtio block. Virtio net supports TSO/GSO. The daemon also monitors card shutdown status and takes appropriate actions like killing the virtio backends and resetting the card upon card shutdown and crashes.

This patch introduces the card "Virtio over PCIe" interface for Intel MIC. It allows virtio drivers on the card to communicate with their user space backends on the host via a device page. Ring 3 apps on the host can add, remove and configure virtio devices. A thin MIC specific virtio_config_ops is implemented which is borrowed heavily from previous similar implementations in lguest and s390 @ drivers/lguest/lguest_device.c drivers/s390/kvm/kvm_virtio.c Co-author: Sudeep Dutt <sudeep.dutt@intel.com> Signed-off-by:

This patch introduces the host "Virtio over PCIe" interface for Intel MIC. It allows creating user space backends on the host and instantiating virtio devices for them on the Intel MIC card. It uses the existing VRINGH infrastructure in the kernel to access virtio rings from the host. A character device per MIC is exposed with IOCTL, mmap and poll callbacks. This allows the user space backend to: (a) add/remove a virtio device via a device page. (b) map (R/O) virtio rings and device page to user space. (c) poll for availability of data. (d) copy a descriptor or entire descriptor chain to/from the card. (e) modify virtio configuration. (f) handle virtio device reset. The buffers are copied over using CPU copies for this initial patch and host initiated MIC DMA support is planned for future patches. The avail and desc virtio rings are in host memory and the used ring is in card memory to maximize writes across PCIe for performance. Co-author: Sudeep Dutt <sudeep.dutt@intel.com> Signed-off-by:

This patch does the following: a) Initializes the Intel MIC X100 platform device and driver. b) Sets up support to handle shutdown requests from the host. c) Maps the device page after obtaining the device page address from the scratchpad registers updated by the host. d) Informs the host upon a card crash by registering a panic notifier. e) Informs the host upon a poweroff/halt event.

This patch enables the following features: a) Boots and shuts down the card via sysfs entries. b) Allocates and maps a device page for communication with the card driver and updates the device page address via scratchpad registers. c) Provides sysfs entries for shutdown status, kernel command line, ramdisk and log buffer information.

This patch enables the following features: a) MSIx, MSI and legacy interrupt support. b) System Memory Page Table(SMPT) support. SMPT enables system memory access from the card. On X100 devices the host can program 32 SMPT registers each capable of accessing 16GB of system memory address space from X100 devices. The registers can thereby be used to access a cumulative 512GB of system memory address space from X100 devices at any point in time. Co-author: Sudeep Dutt <sudeep.dutt@intel.com> Signed-off-by:

Allwinner has electric fuses (efuse) on their line of chips. This driver reads those fuses, seeds the kernel entropy and exports them as a sysfs node. These fuses are most likely to be programmed at the factory, encoding things like Chip ID, some sort of serial number, etc. and appear to be reasonably unique. While in theory, these should be writeable by the user, it will probably be inconvenient to do so. Allwinner recommends that a certain input pin, labeled 'efuse_vddq', be connected to GND. To write these fuses however, a 2.5 V programming voltage needs to be applied to this pin. Even so, they can still be used to generate a board-unique mac from, board unique RSA key and seed the kernel RNG. On sun7i additional storage is available, this is initially used for an UEFI BOOT key, Secure JTAG key, HDMI-HDCP key and vendor specific keys. Currently supported are the following known chips: Allwinner sun4i (A10) Allwinner sun5i (A10s, A13) Allwinner sun7i (A20) Signed-off-by:

kvp_daemon does some operations which take an unpredicable amount of time. In addition the kernel driver gives the kvp_daemon a 5 second timeout to respond to message from the host. If an operation such as getaddrinfo takes a long time and the timeout triggers then netlink errors occour. As a result of such errors the daemon just terminates and the service becomes unavailable. Idendifying and fixing these shortcomings in the kernel-userland communication protocol will be done in separate patches. This change fixes just one obvious timeout bug. Update kvp_get_domain_name to not return a value, better diagnostic for the consumer of the hostname string, remove trailing newline in error case, use snprintf to not overrun output buffer, get hostname only once and return the cached result.
