Subject: [PATCH 2/6] usb: host: xhci-plat: add quirk for XHCI_NO_64BIT_SUPPORT
Date: Tue,  9 Jun 2020 19:12:41 +0800	[thread overview]
Message-ID: <1591701165-12872-3-git-send-email-jun.li@nxp.com> (raw)
In-Reply-To: <1591701165-12872-1-git-send-email-jun.li@nxp.com>

Some dwc3 based platforms may also have the problem AC64 bit (bit 0)
of HCCPARAMS1 set to be 1 but the controller actually can't support
64-bit address when SoC integration, so enable XHCI_NO_64BIT_SUPPORT
via dts property "snps,xhci-dis-64bit-support-quirk".
