[PATCH 0/3] media: rockchip: add support for the RK3576 Video Capture unit

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

This series adds support for the Video Capture (VICAP) unit of the
Rockchip RK3576 to the rkcif driver.

The RK3576 VICAP features a digital video port (DVP) and five MIPI
CSI-2 capture interfaces. Compared to the RK3588 variant, the MIPI
register blocks are laid out differently, the ID_CTRL0 bit layout has
changed, the VC/DT filter has moved from ID_CTRL0 to ID_CTRL1, and the
capture size is configured in the new ID_SET_SIZE register. In
addition, the pixel clock of each MIPI port enters the VICAP through a
dedicated gate in the clock and reset unit, so the VICAP claims five
interface clocks and five interface resets.

The device tree node connects the VICAP to the two MIPI CSI-2
receivers that are usable with the MIPI D-PHYs in full mode, following
the approach taken for the RK3588.

Tested on a Radxa ROCK 4D with a Radxa Camera 4K, whose Sony IMX415
sensor is wired to the first MIPI D-PHY in full mode.

This series applies on top of the RK3576 MIPI CSI-2 receiver
series [1].
