Subject: [PATCH 09/22] ARM: dts: sun8i: v3s: Add nodes for MIPI CSI-2 support
Date: Fri, 10 Sep 2021 20:41:34 +0200 [thread overview]
Message-ID: <20210910184147.336618-10-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20210910184147.336618-1-paul.kocialkowski@bootlin.com>
MIPI CSI-2 is supported on the V3s with an A31-based MIPI CSI-2 bridge
controller. The controller uses a separate D-PHY, which is the same
that is otherwise used for MIPI DSI, but used in Rx mode.
On the V3s, the CSI0 controller is dedicated to MIPI CSI-2 as it does
not have access to any parallel interface pins.
Add all the necessary nodes (CSI0, MIPI CSI-2 bridge and D-PHY) to
support the MIPI CSI-2 interface.
Note that a fwnode graph link is created between CSI0 and MIPI CSI-2
even when no sensor is connected. This will result in a probe failure
for the controller as long as no sensor is connected but this is fine
since no other interface is available.
