+Description:
+ Stores the PLL frequency in Hz for channel Y.
+ Reading returns the actual frequency in Hz.
+ The ADF4371 has an integrated VCO with fundamendal output
+ frequency ranging from 4000000000 Hz 8000000000 Hz.
+
+ out_altvoltage0_frequency:
+ A divide by 1, 2, 4, 8, 16, 32 or circuit generates
+ frequencies from 62500000 Hz to 8000000000 Hz.
+ out_altvoltage1_frequency:
+ This channel duplicates the channel 0 frequency
+ out_altvoltage2_frequency:
+ A frequency doubler generates frequencies from
+ 8000000000 Hz to 16000000000 Hz.
+ out_altvoltage3_frequency:
+ A frequency quadrupler generates frequencies from
+ 16000000000 Hz to 32000000000 Hz.
+
+ Note: writes to one of the channels will affect the frequency of
+ all the other channels, since it involves changing the VCO
+ fundamental output frequency.

+Industrial IIO configfs support
+===============================
+
+1. Overview
+===========
+
+Configfs is a filesystem-based manager of kernel objects. IIO uses some
+objects that could be easily configured using configfs (e.g.: devices,
+triggers).
+
+See Documentation/filesystems/configfs/configfs.txt for more information
+about how configfs works.
+
+2. Usage
+========
+
+In order to use configfs support in IIO we need to select it at compile
+time via CONFIG_IIO_CONFIGFS config option.
+
+Then, mount the configfs filesystem (usually under /config directory)::
+
+ $ mkdir /config
+ $ mount -t configfs none /config
+
+At this point, all default IIO groups will be created and can be accessed
+under /config/iio. Next chapters will describe available IIO configuration
+objects.
+
+3. Software triggers
+====================
+
+One of the IIO default configfs groups is the "triggers" group. It is
+automagically accessible when the configfs is mounted and can be found
+under /config/iio/triggers.
+
+IIO software triggers implementation offers support for creating multiple
+trigger types. A new trigger type is usually implemented as a separate
+kernel module following the interface in include/linux/iio/sw_trigger.h::
+
+ /*
+ * drivers/iio/trigger/iio-trig-sample.c
+ * sample kernel module implementing a new trigger type
+ */
+ #include <linux/iio/sw_trigger.h>
+
+
+ static struct iio_sw_trigger *iio_trig_sample_probe(const char *name)
+ {
+ /*
+ * This allocates and registers an IIO trigger plus other
+ * trigger type specific initialization.
+ */
+ }
+
+ static int iio_trig_hrtimer_remove(struct iio_sw_trigger *swt)
+ {
+ /*
+ * This undoes the actions in iio_trig_sample_probe
+ */
+ }
+
+ static const struct iio_sw_trigger_ops iio_trig_sample_ops = {
+ .probe = iio_trig_sample_probe,
+ .remove = iio_trig_sample_remove,
+ };
+
+ static struct iio_sw_trigger_type iio_trig_sample = {
+ .name = "trig-sample",
+ .owner = THIS_MODULE,
+ .ops = &iio_trig_sample_ops,
+ };
+
+module_iio_sw_trigger_driver(iio_trig_sample);
+
+Each trigger type has its own directory under /config/iio/triggers. Loading
+iio-trig-sample module will create 'trig-sample' trigger type directory
+/config/iio/triggers/trig-sample.
+
+We support the following interrupt sources (trigger types):
+
+ * hrtimer, uses high resolution timers as interrupt source
+
+3.1 Hrtimer triggers creation and destruction
+---------------------------------------------
+
+Loading iio-trig-hrtimer module will register hrtimer trigger types allowing
+users to create hrtimer triggers under /config/iio/triggers/hrtimer.
+
+e.g::
+
+ $ mkdir /config/iio/triggers/hrtimer/instance1
+ $ rmdir /config/iio/triggers/hrtimer/instance1
+
+Each trigger can have one or more attributes specific to the trigger type.
+
+3.2 "hrtimer" trigger types attributes
+--------------------------------------
+
+"hrtimer" trigger type doesn't have any configurable attribute from /config dir.
+It does introduce the sampling_frequency attribute to trigger directory.

- Choose this option to enable carveout heaps with Ion. Carveout heaps
- are backed by memory reserved from the system. Allocation times are
- typically faster at the cost of memory not being used. Unless you
- know your system has these regions, you should say N here.

- Choose this option to enable chunk heaps with Ion. This heap is
- similar in function the carveout heap but memory is broken down
- into smaller chunk sizes, typically corresponding to a TLB size.
- Unless you know your system has these regions, you should say N here.

- The kpc_i2c driver is a hot mess, it should probably be cleaned up a ton. It functions against current hardware though.
-- pcard->card_num in kp2000_pcie_probe() is a global variable and needs atomic / locking / something better.
-- probe_core_uio() probably needs error handling
-- the loop in kp2000_probe_cores() that uses probe_core_uio() also probably needs error handling
-- would be nice if the AIO fileops in kpc_dma could be made to work
- - probably want to add a CONFIG_ option to control compilation of the AIO functions
