* misc: bh1780: probe from compatible stringLinus Walleij2013-10-03
| | | | | | | | | | Currently the BH1780GLI I2C driver relies on the device tree node having the right name, but this is fragile. Use the compatible string to probe the driver instead.

| | | | | | | | | | | | | | | | | | | Make open counter to be incremented and decremented from mei_cl_link and mei_cl_unlik function respectively Nfc was assuming symmetric linking API and thus open handler count was never decreased. This patch fixes that. We need to add separate open hander count for amthif which is handled out of link/unlink functions and doesn't break the symmetric API. Last we do not waste clients slots if amthif or wd are not present in the device. we don't need to allocates slots ahead it is all covered by link/unlink before the devices is responding to user space connection and thus not racing on allocation Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* | misc: mic: depend on X86 for both host and card drivers.Sudeep Dutt2013-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes build failures seen on certain non X86 architectures. The card driver should correctly always depend on X86. The host driver can potentially work on non X86 architectures although it has never been built or validated in such configurations. The host driver dependency on X86 can be removed at some point in the future but this workaround is required for now.

* | Intel MIC Card Driver Changes for Virtio Devices.Ashutosh Dixit2013-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by: Caz Yokoyama <Caz.Yokoyama@intel.com> Signed-off-by: Dasaratharaman Chandramouli <dasaratharaman.chandramouli@intel.com> Signed-off-by: Nikhil Rao <nikhil.rao@intel.com> Signed-off-by: Harshavardhan R Kharche <harshavardhan.r.kharche@intel.com> Signed-off-by: Sudeep Dutt <sudeep.dutt@intel.com> Acked-by: Yaozu (Eddie) Dong <eddie.dong@intel.com> Reviewed-by: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* | Intel MIC Host Driver Changes for Virtio Devices.Ashutosh Dixit2013-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ARM: sunxi: Initial support for Allwinner's Security ID fusesOliver Schinagl2013-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Oliver Schinagl <oliver@schinagl.nl> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
