title: Intersil ISL79987 Analog to MIPI CSI-2 decoder
maintainers:
- Michael Tretter <m.tretter@pengutronix.de>

description:
The Intersil ISL79987 is an analog to MIPI CSI-2 decoder which is capable of
receiving up to four analog stream and multiplexing them into up to four MIPI
CSI-2 virtual channels, using one MIPI clock lane and 1/2 data lanes.
