openamp: OpenAMP_TTY_echo

[EOF]

Hello!

If I run the openAMP example I can see the two new devices appear in the linux /dev folder: ttyRPMSG0 and ttyRPMSG1, so that's fine!

I would like to give these entries another name, like instead of

ttyRPMSG0 --> KEYS

ttyRPMSG1 --> FRAM

Question 1: Can I "force" Linux somehow to use specific custom names that I supply via the M4 while creating an endpoint or does Linux name them always in its own way ("like ttyRPMSGxyz")?

I tried to use the parameter "name" of the function "rpmsg_create_ept()" but another value than the default "rpms-tty" leads to the strange effect, that the channel is created with the new name (checked with "dmesg") but in the /dev folder the device does not appear at all anymore. It only appears, if the default name "rpmsg-tty" is kept.

Question 2: Why does the device no longer appear in the /dev folder, if I give parameter "name" another value than "rpmsg-tty"?
