* Sony 1/2.5-Inch 8.51Mp CMOS Digital Image Sensor
The Sony imx274 is a 1/2.5-inch CMOS active pixel digital image sensor with
an active array size of 3864H x 2202V. It is programmable through I2C
interface. The I2C address is fixed to 0x1a as per sensor data sheet.
Image data is sent through MIPI CSI-2, which is configured as 4 lanes
at 1440 Mbps.
Required Properties:
- compatible: value should be "sony,imx274" for imx274 sensor
- reg: I2C bus address of the device
Optional Properties:
- reset-gpios: Sensor reset GPIO
- clocks: Reference to the input clock.
- clock-names: Should be "inck".
- VANA-supply: Sensor 2.8v analog supply.
- VDIG-supply: Sensor 1.8v digital core supply.
- VDDL-supply: Sensor digital IO 1.2v supply.
The imx274 device node should contain one 'port' child node with
an 'endpoint' subnode. For further reading on port node refer to
Documentation/devicetree/bindings/media/video-interfaces.txt.
Example:
sensor@1a {

- A buffer is allocated either in consistent (it will be automatically
coherent between the CPU and the bus) or non-consistent memory. The
latter can provide performance gains, for instance the CPU cache
sync/flush operations can be avoided if the buffer is accessed by the
corresponding device only and the CPU does not read/write to/from that
buffer. However, this requires extra care from the driver -- it must
guarantee memory consistency by issuing a cache flush/sync when
consistency is needed. If this flag is set V4L2 will attempt to
allocate the buffer in non-consistent memory. The flag takes effect
only if the buffer is used for :ref:`memory mapping <mmap>` I/O and the

-------------------------
:Architectures: s390
This capability enables a guest to set information about its control program
(i.e. guest kernel type and version). The information is helpful during
system/firmware service events, providing additional data about the guest
environments running on the machine.
The information is associated with the DIAGNOSE 0x318 instruction, which sets
an 8-byte value consisting of a one-byte Control Program Name Code (CPNC) and
a 7-byte Control Program Version Code (CPVC). The CPNC determines what
environment the control program is running in (e.g. Linux, z/VM...), and the
CPVC is used for information specific to OS (e.g. Linux version, Linux
distribution...)
If this capability is available, then the CPNC and CPVC can be synchronized
between KVM and userspace via the sync regs mechanism (KVM_SYNC_DIAG318).
