[PATCH 3/9] media: rockchip: rkcif: add support for rk3588 vicap mipi capture
Michael Riesch via B4 Relay

Fri Mar 13 08:20:45 PDT 2026
From: Michael Riesch <michael.riesch at collabora.com>
The RK3588 Video Capture (VICAP) unit features a Digital Video Port
(DVP) and six MIPI CSI-2 capture interfaces. Add initial support
for this variant to the rkcif driver and enable the MIPI CSI-2
capture interfaces.
