Subject: [PATCH 3/3] arm64: dts: mediatek: mt8195: Add mediatek,rxfifo-depth to cherry
Date: Wed, 13 Dec 2023 14:35:43 +0800	[thread overview]
Message-ID: <20231213063543.12435-3-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <20231213063543.12435-1-chunfeng.yun@mediatek.com>

Add the quirk property "mediatek,rxfifo-depth" to work around Gen1 isoc-in
transfer issue which send out unexpected ACK even after device already
finished the burst transfer with a short patcket, specially for a 4K
camera device.
