+    <title>Comparison with old cropping API.</title>
+
+<para>The selection API was introduced to cope with deficiencies of previous
+<link linkend="crop"> API </link>, that was designed to control simple capture
+devices. Later the cropping API was adopted by video output drivers. The ioctls
+are used to select a part of the display were the video signal is inserted. It
+should be considered as an API abuse because the described operation is
+actually the composing.  The selection API makes a clear distinction between
+composing and cropping operations by setting the appropriate targets.  The V4L2
+API lacks any support for composing to and cropping from an image inside a
+memory buffer.  The application could configure a capture device to fill only a
+part of an image by abusing V4L2 API.  Cropping a smaller image from a larger
+one is achieved by setting the field <structfield>
+&v4l2-pix-format;::bytesperline </structfield>.  Introducing an image offsets
+could be done by modifying field <structfield> &v4l2-buffer;::m:userptr
+</structfield> before calling <constant> VIDIOC_QBUF </constant>. Those
+operations should be avoided because they are not portable (endianness), and do
+not work for macroblock and Bayer formats and mmap buffers.  The selection API
+deals with configuration of buffer cropping/composing in a clear, intuitive and
+portable way.  Next, with the selection API the concepts of the padded target
+and constraints flags are introduced.  Finally, <structname> &v4l2-crop;
+</structname> and <structname> &v4l2-cropcap; </structname> have no reserved
+fields. Therefore there is no way to extend their functionality.  The new
+<structname> &v4l2-selection; </structname> provides a lot of place for future
+extensions.  Driver developers are encouraged to implement only selection API.
+The former cropping API would be simulated using the new one. </para>

+BIOS versions based in the ACPI 4.0 specification have limited options
+to control where the errors are injected.  Your BIOS may support an
+extension (enabled with the param_extension=1 module parameter, or
+boot command line einj.param_extension=1). This allows the address
+and mask for memory injections to be specified by the param1 and
+param2 files in apei/einj.
+
+BIOS versions using the ACPI 5.0 specification have more control over
+the target of the injection. For processor related errors (type 0x1,
+0x2 and 0x4) the APICID of the target should be provided using the
+param1 file in apei/einj. For memory errors (type 0x8, 0x10 and 0x20)

+An ACPI 5.0 BIOS may also allow vendor specific errors to be injected.

+creativity in using this feature expands beyond our expectations).

+Device State Configuration Registers
+------------------------------------
+
+TI C6X SoCs contain a region of miscellaneous registers which provide various
+function for SoC control or status. Details vary considerably among from SoC
+to SoC with no two being alike.
+
+In general, the Device State Configuraion Registers (DSCR) will provide one or
+more configuration registers often protected by a lock register where one or
+more key values must be written to a lock register in order to unlock the
+configuration register for writes. These configuration register may be used to
+enable (and disable in some cases) SoC pin drivers, select peripheral clock
+sources (internal or pin), etc. In some cases, a configuration register is
+write once or the individual bits are write once. In addition to device config,
+the DSCR block may provide registers which which are used to reset peripherals,
+provide device ID information, provide ethernet MAC addresses, as well as other
+miscellaneous functions.
+
+For device state control (enable/disable), each device control is assigned an
+id which is used by individual device drivers to control the state as needed.
+
+Required properties:
+
+- compatible: must be "ti,c64x+dscr"
+- reg: register area base and size
+
+Optional properties:
+
+  NOTE: These are optional in that not all SoCs will have all properties. For
+        SoCs which do support a given property, leaving the property out of the
+        device tree will result in reduced functionality or possibly driver
+        failure.
+
+- ti,dscr-devstat
+    offset of the devstat register
+
+- ti,dscr-silicon-rev
+    offset, start bit, and bitsize of silicon revision field
+
+- ti,dscr-rmii-resets
+    offset and bitmask of RMII reset field. May have multiple tuples if more
+    than one ethernet port is available.
+
+- ti,dscr-locked-regs
+    possibly multiple tuples describing registers which are write protected by
+    a lock register. Each tuple consists of the register offset, lock register
+    offsset, and the key value used to unlock the register.
+

+    offset and key values of two "kick" registers used to write protect other

+
+- ti,dscr-mac-fuse-regs
+    MAC addresses are contained in two registers. Each element of a MAC address
+    is contained in a single byte. This property has two tuples. Each tuple has

+C6X Interrupt Chips
+-------------------
+
+* C64X+ Core Interrupt Controller
+
+  The core interrupt controller provides 16 prioritized interrupts to the
+  C64X+ core. Priority 0 and 1 are used for reset and NMI respectively.
+  Priority 2 and 3 are reserved. Priority 4-15 are used for interrupt
+  sources coming from outside the core.
+
+  Required properties:
+  --------------------
+  - compatible: Should be "ti,c64x+core-pic";
+  - #interrupt-cells: <1>
+
+  Interrupt Specifier Definition
+  ------------------------------
+  Single cell specifying the core interrupt priority level (4-15) where
+  4 is highest priority and 15 is lowest priority.
+
+  Example
+  -------
+  core_pic: interrupt-controller@0 {
+	interrupt-controller;
+	#interrupt-cells = <1>;
+	compatible = "ti,c64x+core-pic";
+  };
+
+
+
+* C64x+ Megamodule Interrupt Controller
+
+  The megamodule PIC consists of four interrupt mupliplexers each of which
+  combine up to 32 interrupt inputs into a single interrupt output which
+  may be cascaded into the core interrupt controller. The megamodule PIC
+  has a total of 12 outputs cascading into the core interrupt controller.
+  One for each core interrupt priority level. In addition to the combined
+  interrupt sources, individual megamodule interrupts may be cascaded to
+  the core interrupt controller. When an individual interrupt is cascaded,
+  it is no longer handled through a megamodule interrupt combiner and is
+  considered to have the core interrupt controller as the parent.
+
+  Required properties:
+  --------------------
+  - compatible: "ti,c64x+megamod-pic"
+  - interrupt-controller
+  - #interrupt-cells: <1>
+  - reg: base address and size of register area
+  - interrupt-parent: must be core interrupt controller
+  - interrupts: This should have four cells; one for each interrupt combiner.
+                The cells contain the core priority interrupt to which the
+                corresponding combiner output is wired.
+
+  Optional properties:
+  --------------------
+  - ti,c64x+megamod-pic-mux: Array of 12 cells correspnding to the 12 core
+                             priority interrupts. The first cell corresponds to
+                             core priority 4 and the last cell corresponds to
+                             core priority 15. The value of each cell is the
+                             megamodule interrupt source which is MUXed to
+                             the core interrupt corresponding to the cell
+                             position. Allowed values are 4 - 127. Mapping for
+                             interrupts 0 - 3 (combined interrupt sources) are
+                             ignored.
+
+  Interrupt Specifier Definition
+  ------------------------------
+  Single cell specifying the megamodule interrupt source (4-127). Note that
+  interrupts mapped directly to the core with "ti,c64x+megamod-pic-mux" will
+  use the core interrupt controller as their parent and the specifier will
+  be the core priority level, not the megamodule interrupt number.
+
+  Examples
+  --------
+  megamod_pic: interrupt-controller@1800000 {
+	compatible = "ti,c64x+megamod-pic";
+	interrupt-controller;
+	#interrupt-cells = <1>;
+	reg = <0x1800000 0x1000>;
+	interrupt-parent = <&core_pic>;
+	interrupts = < 12 13 14 15 >;
+  };
+
+  This is a minimal example where all individual interrupts go through a
+  combiner. Combiner-0 is mapped to core interrupt 12, combiner-1 is mapped
+  to interrupt 13, etc.
+
+
+  megamod_pic: interrupt-controller@1800000 {
+	compatible = "ti,c64x+megamod-pic";
+	interrupt-controller;
+	#interrupt-cells = <1>;
+	reg = <0x1800000 0x1000>;
+	interrupt-parent = <&core_pic>;
+	interrupts = < 12 13 14 15 >;
+	ti,c64x+megamod-pic-mux = <  0  0  0  0
+                                    32  0  0  0
+                                     0  0  0  0 >;
+  };
+
+  This the same as the first example except that megamodule interrupt 32 is
+  mapped directly to core priority interrupt 8. The node using this interrupt
+  must set the core controller as its interrupt parent and use 8 in the
+  interrupt specifier value.
