From: Roger Quadros Date: Tue, 15 Sep 2020 11:45:42 +0000 (+0300) Subject: dt-bindings: usb: cdns,usb3: Add cdns,phyrst-a-enable property X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5261e48f9a705bf65e3d202eb44dc2e270911684;p=linux.git dt-bindings: usb: cdns,usb3: Add cdns,phyrst-a-enable property Controller version 0x0002450D has USB2 PHY RX sensitivity issues that needs to be worked around by enabling phyrst-a-enable bit in PHYRST_CFG register. There is no way to know controller version before device controller is started and the workaround needs to be applied for both host and device modes, so we add this DT property.
