+What:		/dev/<se>_mu[0-9]+_ch[0-9]+
+Date:		May 2024
+KernelVersion:	6.8
+Contact:	linux-imx@nxp.com, pankaj.gupta@nxp.com
+Description:
+		NXP offers multiple hardware IP(s) for secure enclaves like EdgeLock-
+		Enclave(ELE), SECO. The character device file descriptors
+		/dev/<se>_mu*_ch* are the interface between userspace NXP's secure-
+		enclave shared library and the kernel driver.
+
+		The ioctl(2)-based ABI is defined and documented in
+		[include]<linux/firmware/imx/ele_mu_ioctl.h>.
+		ioctl(s) are used primarily for:
+			- shared memory management
+			- allocation of I/O buffers
+			- getting mu info
+			- setting a dev-ctx as receiver to receive all the commands from FW
+			- getting SoC info
+			- send command and receive command response
+
+		The following file operations are supported:
+
+		open(2)
+		  Currently the only useful flags are O_RDWR.
+
+		read(2)
+		  Every read() from the opened character device context is waiting on
+		  wait_event_interruptible, that gets set by the registered mailbox callback
+		  function, indicating a message received from the firmware on message-
+		  unit.
+
+		write(2)
+		  Every write() to the opened character device context needs to acquire
+		  mailbox_lock before sending message on to the message unit.
+
+		close(2)
+		  Stops and frees up the I/O contexts that were associated
+		  with the file descriptor.
