Subject: [PATCH v2 1/2] dt-bindings: usb: dwc3: drop 'snps,host-vbus-glitches-quirk'
Date: Mon, 12 Feb 2024 11:19:07 -0500 [thread overview]
Message-ID: <20240212-vbus-glitch-v2-1-d71b73a82de1@nxp.com> (raw)
In-Reply-To: <20240212-vbus-glitch-v2-0-d71b73a82de1@nxp.com>
Drop 'snps,host-vbus-glitches-quirk'. It is safer to keep vbus disabled
before handing over to xhci driver. Needn't this property to control enable
workaround. Apply workaround unconditional.
