Subject: [RFC PATCH 0/9] I3C Slave Mode support
Date: Tue, 5 Sep 2023 17:38:33 -0400 [thread overview]
Message-ID: <20230905213842.3035779-1-Frank.Li@nxp.com> (raw)
This RFC patch introduces support for I3C slave mode, which is referenced
with a PCIe Endpoint system. It also establishes a configuration framework
(configfs) for the I3C slave controller driver and the I3C slave function
driver
Typic usage as
The user can configure the i3c-slave-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-slave-tty Device to slave Controller
------------------------------------------------
In order for the slave function device to be useful, it has to be bound to
a I3C slave 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-slave/
Host side:
cat /dev/ttyI3C0
Slave side:
echo abc >/dev/ttyI3C0
These patches have not full implemented, especially at tty driver side.
But it does not impact to review i3c slave part, especially data transfer
and configfs.
Frank Li (9):
i3c: add actual in i3c_priv_xfer
i3c: svc: rename read_len as actual_len
i3c: master: svc return actual transfer data len
dt-bindings: i3c: svc: add compatible string i3c: silvaco,i3c-slave-v1
i3c: add slave mode support
i3c: slave: add svc slave controller support
i3c: slave: func: add tty driver
tty: serial: add tty over I3C master side driver
