Subject: [PATCH 0/8] usb: dwc3: add Layerscape SoC support
Date: Wed, 13 Oct 2021 19:44:23 +0200 [thread overview]
Message-ID: <20211013174431.652550-1-michael@walle.cc> (raw)
Primarily, this will add support for peripheral mode on Layerscape SoCs.
For this to work, we have to backport two fixes from linux and fix the
fixup code for the DWC3 controller (which enables snooping because the SoC
has wrong startup defaults).
As a first user of the driver, enable it on the Kontron SL28 board, where
both host and peripheral mode was tested.
OTG mode is not supported. For this to work, one would need to read the
hardware status of the OTG pin in the bind() op. But it isn't allowed to
access the hardware in the bind() op (if I understand Simon correctly).
