LVDS Channel
============
-Each LVDS Channel has to contain a display-timings node that describes the
-video timings for the connected LVDS display. For detailed information, also
-have a look at Documentation/devicetree/bindings/video/display-timing.txt.
+Each LVDS Channel has to contain either an of graph link to a panel device node
+or a display-timings node that describes the video timings for the connected
+LVDS display as well as the fsl,data-mapping and fsl,data-width properties.
Required properties:
- reg : should be <0> or <1>
+ - port: Input and output port nodes with endpoint definitions as defined in
+ Documentation/devicetree/bindings/graph.txt.
+ On i.MX5, the internal two-input-multiplexer is used. Due to hardware
+ limitations, only one input port (port@[0,1]) can be used for each channel
+ (lvds-channel@[0,1], respectively).
+ On i.MX6, there should be four input ports (port@[0-3]) that correspond
+ to the four LVDS multiplexer inputs.
+ A single output port (port@2 on i.MX5, port@4 on i.MX6) must be connected
+ to a panel input port. Optionally, the output port can be left out if
+ display-timings are used instead.
+
+Optional properties (required if display-timings are used):
+ - display-timings : A node that describes the display timings as defined in
+ Documentation/devicetree/bindings/video/display-timing.txt.
- fsl,data-mapping : should be "spwg" or "jeida"
This describes how the color bits are laid out in the
serialized LVDS signal.
- fsl,data-width : should be <18> or <24>
- - port: A port node with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt.
- On i.MX5, the internal two-input-multiplexer is used.
- Due to hardware limitations, only one port (port@[0,1])
- can be used for each channel (lvds-channel@[0,1], respectively)
- On i.MX6, there should be four ports (port@[0-3]) that correspond
- to the four LVDS multiplexer inputs.

(DSA_MAX_SWITCHES).
Each of these switch child nodes should have the following required properties:
-- reg : Describes the switch address on the MII bus
+- reg : Contains two fields. The first one describes the
+ address on the MII bus. The second is the switch
+ number that must be unique in cascaded configurations
- #address-cells : Must be 1
- #size-cells : Must be 0

+Before executing OF unittest, it is required to attach the test data to
machine's device tree (if present). So, when selftest_data_add() is called,
at first it reads the flattened device tree data linked into the kernel image
via the following kernel symbols:
byte 4: 0 y6 y5 y4 y3 y2 y1 y0
byte 5: 0 z6 z5 z4 z3 z2 z1 z0
+Protocol Version 2 DualPoint devices send standard PS/2 mouse packets for
+the DualPoint Stick.
+
Dualpoint device -- interleaved packet format
---------------------------------------------
byte 7: 0 y6 y5 y4 y3 y2 y1 y0
byte 8: 0 z6 z5 z4 z3 z2 z1 z0
+Devices which use the interleaving format normally send standard PS/2 mouse
+packets for the DualPoint Stick + ALPS Absolute Mode packets for the
+touchpad, switching to the interleaved packet format when both the stick and
+the touchpad are used at the same time.
+
ALPS Absolute Mode - Protocol Version 3
---------------------------------------
The kernel does not provide button emulation for such devices but treats
them as any other INPUT_PROP_BUTTONPAD device.
+INPUT_PROP_ACCELEROMETER
+-------------------------
+Directional axes on this device (absolute and/or relative x, y, z) represent
+accelerometer data. All other axes retain their meaning. A device must not mix
+regular directional axes and accelerometer axes on the same event node.

Guidelines:
==========
The guidelines below ensure proper single-touch and multi-finger functionality.
The type of approaching tool. A lot of kernel drivers cannot distinguish
between different tool types, such as a finger or a pen. In such cases, the
-event should be omitted. The protocol currently supports MT_TOOL_FINGER and
-MT_TOOL_PEN [2]. For type B devices, this event is handled by input core;
-drivers should instead use input_mt_report_slot_state().

+MT_TOOL_PEN, and MT_TOOL_PALM [2]. For type B devices, this event is handled
+by input core; drivers should instead use input_mt_report_slot_state().
+A contact's ABS_MT_TOOL_TYPE may change over time while still touching the
+device, because the firmware may not be able to determine which tool is being
+used when it first appears.

+ * coherent read and write operations.
+ *
+ * Instmem can be allocated through two means:

+ * pages contiguous to the GPU. This is the preferred way.
+ * 2) If no IOMMU mapping is probed, the DMA API is used to allocate physically

+ *
+ * In both cases CPU read and writes are performed using PRAMIN (i.e. using the

+ * to use more "relaxed" allocation parameters when using the DMA API, since we
+ * never need a kernel mapping.
