Subject: [PATCH 0/1] can: esd_usb: Add support for esd CAN-USB/3
Date: Fri, 28 Jul 2023 17:08:56 +0200	[thread overview]
Message-ID: <20230728150857.2374886-1-frank.jungclaus@esd.eu> (raw)

After having applied a vast number of improvements to the existing
CAN-USB/2 driver here now is a new attempt to add support for the esd
CAN-USB/3 CAN FD interface.

Beside this patch there are the following to-do's left for follow-up
patches:

* In principle, the esd CAN-USB/3 supports Transmitter Delay
Compensation (TDC), but currently only the automatic TDC mode is
supported by this driver. An implementation for manual TDC
configuration will follow.

* Rework the code to no longer switch directly on the USB product IDs
to handle different device setting for each supported USB
device. Instead use the driver_info member within struct usb_device_id
to hold / point to specific properties for each supported device.

* Try to switch from synchronous send usb_bulk_msg() to asynchronous
communication by means of usb_submit_urb() where it is feasible.
