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
