PATCH v3 1/3 dt-bindings: usb: Add binding for WCH CH334/CH335 hub controller
From: Chaoyi Chen <[email protected]>
The WCH CH334/CH335[0] are USB2.0 protocol compliant 4-port USB HUB controller chips, supporting USB2.0 high-speed and full-speed for upstream ports, and USB2.0 high-speed 480Mbps, full-speed 12Mbps and low-speed 1.5Mbps for downstream ports, supporting not only low-cost STT mode (single TT schedules 4 downstream ports in time share), but also supports high performance MTT mode (4 TTs each corresponding to 1 port, concurrent processing).
Add a device tree binding for it.

Yes, it is active-low, so during normal operation it should be set to high.

There's also a timing that needs to be respected after a power-on event so that the reset has enough time to be performed, c.f. 3.2.1 Power-on Reset in the datasheet you linked to in the commit log. How are you making sure we wait those (apparently, the wording in the datasheet is confusing) 14ms?
