@@ -8,34 +8,66 @@ The crucial structure for device drivers in iio is iio_dev.
 
 First allocate one using:
 
-struct iio_dev *indio_dev = iio_allocate_device();
+struct iio_dev *indio_dev = iio_allocate_device(sizeof(struct chip_state));
+where chip_state is a structure of local state data for this instance of
+the chip.
 
-Then fill in the following:
-
-indio_dev->dev.parent
-  the struct device associated with the underlying hardware.
-
-indio_dev->num_interrupt_lines
-   number of event triggering hardware lines the device has.
+That data can be accessed using iio_priv(struct iio_dev *)
 
-indio_dev->event_attrs
-   attributes used to enable / disable hardware events - note the
-   attributes are embedded in iio_event_attr structures with an
-   associated iio_event_handler which may or may note be shared.
-   If num_interrupt_lines = 0, then no need to fill this in.
-
-indio_dev->attrs
-   general attributes such as polled access to device channels.
+Then fill in the following:
 
-indio_dev->dev_data
-   private device specific data.
+- indio_dev->dev.parent
+	Struct device associated with the underlying hardware.
+- indio_dev->name
+	Name of the device being driven - made available as the name
+	attribute in sysfs.
 
-indio_dev->driver_module
-   typically set to THIS_MODULE. Used to specify ownership of some
-   iio created resources.
+- indio_dev->info
+	pointer to a structure with elements that tend to be fixed for
+	large sets of different parts supported by a given driver.
+	This contains:
+	* info->driver_module:
+		Set to THIS_MODULE. Used to ensure correct ownership
+		of various resources allocate by the core.
+	* info->num_interrupt_lines:
+		Number of event triggering hardware lines the device has.
+	* info->event_attrs:
+		Attributes used to enable / disable hardware events.
+	* info->attrs:
+		General device attributes. Typically used for the weird
+		and the wonderful bits not covered by the channel specification.
+	* info->read_raw:
+		Raw data reading function. Used for both raw channel access
+		and for associate parameters such as offsets and scales.
+	* info->write_raw:
+		Raw value writing function. Used for writable device values such
+		as DAC values and caliboffset.
+	* info->read_event_config:
+		Typically only set if there are some interrupt lines.  This
+		is used to read if an on sensor event detector is enabled.
+	* info->write_event_config:
+		Enable / disable an on sensor event detector.
+	* info->read_event_value:
+		Read value associated with on sensor event detectors. Note that
+		the meaning of the returned value is dependent on the event
+		type.
+	* info->write_event_value:
+		Write the value associated with on sensor event detectors. E.g.
+		a threshold above which an interrupt occurs.  Note that the
+		meaning of the value to be set is event type dependant.
 
-indio_dev->modes
-   whether direct access and / or ring buffer access is supported.
+- indio_dev->modes:
+	Specify whether direct access and / or ring buffer access is supported.
+- indio_dev->ring:
+	An optional associated buffer.
+- indio_dev->pollfunc:
+	Poll function related elements. This controls what occurs when a trigger
+	to which this device is attached sends and event.
+- indio_dev->channels:
+	Specification of device channels. Most attributes etc are built
+	form this spec.
+- indio_dev->num_channels:
+	How many channels are there?
 
 Once these are set up, a call to iio_device_register(indio_dev),
 will register the device with the iio core.

 /**
+ * struct iio_chan_spec - specification of a single channel

+ * @channel2:		If there is a second number for a differential
+ *			channel then this is it. If modified is set then the
+ *			value here specifies the modifier.
+ * @address:		Driver specific identifier.
+ * @scan_index:	Monotonic index to give ordering in scans when read
+ *			from a buffer.
+ * @scan_type:		Sign:		's' or 'u' to specify signed or unsigned
+ *			realbits:	Number of valid bits of data
+ *			storage_bits:	Realbits + padding
+ *			shift:		Shift right by this before masking out
+ *					realbits.
+ * @info_mask:		What information is to be exported about this channel.
+ *			This includes calibbias, scale etc.
+ * @event_mask:	What events can this channel produce.
+ * @extend_name:	Allows labeling of channel attributes with an
+ *			informative name. Note this has no effect codes etc,
+ *			unlike modifiers.
+ * @processed_val:	Flag to specify the data access attribute should be
+ *			*_input rather than *_raw.
+ * @modified:		Does a modifier apply to this channel. What these are
+ *			depends on the channel type.  Modifier is set in
+ *			channel2. Examples are IIO_MOD_X for axial sensors about
+ *			the 'x' axis.
+ * @indexed:		Specify the channel has a numerical index. If not,
+ *			the value in channel will be suppressed for attribute
+ *			but not for event codes. Typically set it to 0 when
+ *			the index is false.
