[RFC PATCH 0/5] media: rockchip: rkisp2: Add driver for ISP on Rk3588

[Paul Elder <paul.elder@ideasonboard.com>]

Hello everyone!

This patch series adds a new rkisp2 driver that aims to support all
Rockchip 2.x and 3.x series ISPs. Here we add support for the version on
the RK3588, which as far as I'm aware is a 3.0.

Patches 1 and 2 add dt bindings and dt nodes; patches 3~5 add the actual
driver.

All my discussion points/questions/progress-reports are in patch 3.

The following two series [0] [1] will be helpful for testing the code,
as they enable the VICAP module to work on the RK3588. I've tested this
on the Orange Pi CM5 Base with an imx219. I have a branch here [2] for
convenience. A libcamera branch will be coming soon too!
