[PATCH v2 0/2] Add MIPI CSI-2 receiver support for RK3576

[Amin Gattout <amin.gattout@gmail.com>]

This series adds the device tree binding and the SoC nodes for the
MIPI CSI-2 receiver units of the Rockchip RK3576. The receiver is the
same Synopsys DesignWare IP as in the RK3568 and the register map is
identical, so the existing driver is used unchanged via a fallback
compatible.

Only the two receivers fed by the Innosilicon D-PHYs in full mode
(MIPI1 and MIPI3) are added; see patch 2 for the details.

Tested on a Radxa ROCK 4D, whose camera connector is wired to the first
Innosilicon D-PHY in full mode, that is to CSI-2 receiver MIPI1. With a
Radxa Camera 4K, based on a Sony IMX415 sensor streaming four lanes at a
445.5 MHz link frequency, frames were captured in SGBRG10 at 3864x2192
through the VICAP unit, both from the sensor internal test pattern and
from real scenes.

This series depends on the RK3576 CSI D-PHY series [1], which provides
the csi_dphy0/csi_dphy1 nodes referenced here.
