[PATCH v13 00/11] Rockchip ISP Driver

[Helen Koike]

Hi,

This patchset adds support for the Image Signal Processor unit version 1.0 of
the Rockchip RK3399 SoC in the staging tree.

There are still some missing things to move it from staging (please, see
TODO file), but the driver is already being used by several people.

For instance, libcamera, currently supports an older version of the driver;
and adding in staging make the work flow easier for collaboration within
the community.

I plan to be actively working on the driver to move it out of staging as soon as possible.

It is also available at
https://gitlab.collabora.com/koike/linux/tree/rockchip/isp/v13

NOTE: This series only touches MAINTAINERS file and drivers/staging/

Major changes in v13
--------------------
* From v12 discussions, this dphy driver will only be used for rx0, as
the tx1rx1 will be provided by the dsi controller driver as pointed by
Heiko. So in this version we renamed the driver from phy-rockchip-dphy
to phy-rockchip-dphy-rx0, we also renamed the configs and the bindings,
to make it clear it is specific to rx0.

* Fixed typo and improved text descriptions as pointed by Laurent, Ezequiel
and Sakari in v12.

* Removed redundant TESTCLK=1.

* Replaced do_div by div_u64 for data_rate calculation.

* Removed useless grf lookup by phandle.

* Removed space from bus info, to make it "platform:rkisp1", similar to
"platform:vivid" and "platform:vimc".

* Minor coding style changes.

NOTE: there is a failure in v4l2-compliance, but comes from the sensor, not from the ISP.
