Does A-PHY support MIPI CSI-2 and DSI-2?

Yes. MIPI A-PHY is the only long-reach SerDes standard to support CSI-2 and DSI-2. All available MIPI CSI-2 and DSI-2 versions will be supported via protocol adaptation layers (PAL/CSI-2 and PAL/DSI-2). These protocol adaptation layers are expected to be released in early 2021.
