Subject: [PATCH 0/2] Allwinner H6 USB3 device tree updates
Date: Tue, 20 Apr 2021 23:28:32 -0500	[thread overview]
Message-ID: <20210421042834.27309-1-samuel@sholland.org> (raw)

While implementing support for this USB controller in U-Boot, I noticed
that the reset line alsp affects they PHY. It looks like most platforms
use a separate glue node to represent this, and in fact there is already
a compatible for the H6 listed in drivers/usb/dwc3/dwc3-of-simple.c.

Since this layout matches the usual way of modeling this hardware, it
allows using the existing drivers without adding platform-specific code.
