+What: /sys/bus/iio/devices/iio:deviceX/frequency
+KernelVersion:
+Contact: linux-iio@vger.kernel.org
+Description:
+ Stores the PLL frequency in Hz for output channels.
+ Reading returns the frequency in Hz.

+What: /sys/bus/iio/devices/iio:deviceX/muxout_select
+KernelVersion:
+Contact: linux-iio@vger.kernel.org
+Description:
+ The mux output allows the user to access various internal points on
+ the chip. Valid values that can be written are:
+ * high_z -> high impedance output
+ * lock_detect -> digital lock detector output
+ * muxout_low -> low output
+ * f_div_rclk_2 -> fdiv_rclk/2
+ * f_div_nclk_2 -> fdiv_nclk/2
+ * muxout_high -> high output
+
+What: /sys/bus/iio/devices/iio:deviceX/muxout_select_available
+KernelVersion:
+Contact: linux-iio@vger.kernel.org
+Description:
+ Reading this returns the valid values that can be written to the
+ muxout_mode attribute:
+ * high_z
+ * lock_detect
+ * muxout_low
+ * f_div_rclk_2
+ * f_div_nclk_2
+ * muxout_high
