Subject: [PATCH v5 3/5] media: platform: mediatek: isp_30: add mediatek
ISP3.0 sensor interface
From: Louis Kuo <louis.kuo@...iatek.com>
This will add the mediatek ISP3.0 seninf (sensor interface) driver found
on several Mediatek SoCs such as the mt8365.
Then seninf module has 4 physical CSI-2 inputs. Depending on the soc they
may not be all connected.
