It also establishes a configuration framework (configfs) for the I3C target controller driver and the I3C target function driver Typic usage as The user can configure the i3c-target-tty device using configfs entry. In order to change the vendorid, the following commands can be used # echo 0x011b > functions/tty/func1/vendor_id # echo 0x1000 > functions/tty/func1/part_id # echo 0x6 > functions/tty/t/bcr Binding i3c-target-tty Device to target Controller ------------------------------------------------ In order for the target function device to be useful, it has to be bound to a I3C target controller driver. Use the configfs to bind the function device to one of the controller driver present in the system:: # ln -s functions/pci_epf_test/func1 controllers/44330000.i3c-target/ Host side: cat /dev/ttyI3C0 Taret side: echo abc >/dev/ttyI3C0 Chagne from v2 to v3 - using 'mode' distingiush master and target. - move svc-i3c-target.c to under master, - built together with svc-i3c-master.c Change from v1 to v2 - change "slave" to "target" - include master side tty patch - fixed dtbcheck problem - fixed kerne-doc check warning Some review comment may be lost since it is quite long time since v1. Now master side dependent patches already in linux-next. So sent target side patches with tty support again. No sure why an additional "\r\n" appended.
