Subject: [PATCH 1/3] dt-bindings: usb: mtk-xhci: add a new property for broken streams
Date: Wed, 16 Dec 2020 19:51:23 +0800 [thread overview]
Message-ID: <20201216115125.5886-1-chunfeng.yun@mediatek.com> (raw)
The 0.96 xHCI controller on some platforms does not support
bulk stream even HCCPARAMS says supporting, due to MaxPSASize
is set a non-zero default value by mistake, so add a new
property "mediatek,broken_streams_quirk" to fix it.
