[PATCH v3 0/5] media: rockchip: rkisp2: Add driver for ISP on Rk3588

[Paul Elder]

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.

Notable changes from the RFC version:
- fixed a couple potential page fault storms
- use extensible stats (previously only params were extensible)
- no more subdev pad crops; all cropping has been moved to parameter
  buffers so that they can be configured synchronously
- the DMA RX sink pads and the main/self path source pads on the ISP
  subdev have been split into individual pads
- an unused sink pad has been allocated on the ISP subdev for future
  inline mode support (to prevent uapi from changing)

Changes in v3:
- add explicit padding to uapi structs
- reorder patches so that dt goes last
- move uapi header to a nicer location

This series is based on the latest version (v7.2-rc1) (at the time of
posting) of media-commiters/next [0], with some patches on top for
testing on the Orange Pi CM5 Base with an imx708. I have a branch [1]
that integrates this series on top of said patches and
media-committers/next.

Corresponding libcamera patches+branch will be coming soon (within
minutes), but since I cannot send and link these simultanously, you will
have to search the libcamera mailing list :) I'll be sending a v3 to
match the driver v3.
