Subject[PATCH v2 3/3] arm64: dts: mediatek: mt8195: Add 'rx-fifo-depth' for cherry
Date
Add the quirk property "rx-fifo-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.
