+Atmel Image Sensor Controller (ISC)
+----------------------------------------------
+
+Required properties for ISC:
+- compatible
+ Must be "atmel,sama5d2-isc".
+- reg
+ Physical base address and length of the registers set for the device.
+- interrupts
+ Should contain IRQ line for the ISC.
+- clocks
+ List of clock specifiers, corresponding to entries in
+ the clock-names property;
+ Please refer to clock-bindings.txt.
+- clock-names

+*************
+Touch Devices
+*************
+
+Touch devices are accessed through character device special files named
+``/dev/v4l-touch0`` to ``/dev/v4l-touch255`` with major number 81 and
+dynamically allocated minor numbers 0 to 255.
+
+Overview
+========
+
+Sensors may be Optical, or Projected Capacitive touch (PCT).
+
+Processing is required to analyse the raw data and produce input events. In
+some systems, this may be performed on the ASIC and the raw data is purely a
+side-channel for diagnostics or tuning. In other systems, the ASIC is a simple
+analogue front end device which delivers touch data at high rate, and any touch
+processing must be done on the host.
+
+For capacitive touch sensing, the touchscreen is composed of an array of
+horizontal and vertical conductors (alternatively called rows/columns, X/Y
+lines, or tx/rx). Mutual Capacitance measured is at the nodes where the
+conductors cross. Alternatively, Self Capacitance measures the signal from each
+column and row independently.
+
+A touch input may be determined by comparing the raw capacitance measurement to
+a no-touch reference (or "baseline") measurement:
+
+Delta = Raw - Reference
+
+The reference measurement takes account of variations in the capacitance across
+the touch sensor matrix, for example manufacturing irregularities,
+environmental or edge effects.
+
+Querying Capabilities
+=====================
+
+Devices supporting the touch interface set the ``V4L2_CAP_VIDEO_CAPTURE`` flag
+and the ``V4L2_CAP_TOUCH`` flag in the ``capabilities`` field of
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+At least one of the read/write or streaming I/O methods must be
+supported.
+
+The formats supported by touch devices are documented in
+:ref:`Touch Formats <tch-formats>`.
+
+Data Format Negotiation
+=======================
+
+A touch device may support any I/O method.

+/*
+ * BEWARE OF KNOWN ISSUES WITH VIDEO QUALITY
+ *
+ * This driver was developed by Bluecherry LLC by deducing behaviour of
+ * original manufacturer's driver, from both source code and execution traces.
+ * It is known that there are some artifacts on output video with this driver:
+ * - on all known hardware samples: random pixels of wrong color (mostly
+ * white, red or blue) appearing and disappearing on sequences of P-frames;
+ * - on some hardware samples (known with H.264 core version e006:2800):
+ * total madness on P-frames: blocks of wrong luminance; blocks of wrong
+ * colors "creeping" across the picture.
+ * There is a workaround for both issues: avoid P-frames by setting GOP size
+ * to 1. To do that, run this command on device files created by this driver:
+ *
+ * v4l2-ctl --device /dev/videoX --set-ctrl=video_gop_size=1
+ *
+ * These issues are not decoding errors; all produced H.264 streams are decoded
+ * properly. Streams without P-frames don't have these artifacts so it's not
+ * analog-to-digital conversion issues nor internal memory errors; we conclude
+ * it's internal H.264 encoder issues.
+ * We cannot even check the original driver's behaviour because it has never
+ * worked properly at all in our development environment. So these issues may
+ * be actually related to firmware or hardware. However it may be that there's
+ * just some more register settings missing in the driver which would please
+ * the hardware.
+ * Manufacturer didn't help much on our inquiries, but feel free to disturb
+ * again the support of Intersil (owner of former Techwell).

-
- Currently supported chips:
- - TW6864 (4 video channels),
- - TW6865 (4 video channels, not tested, second generation chip),
- - TW6868 (8 video channels but only 4 first channels using
- built-in video decoder are supported, not tested),
