We can reuse the src from fsl,imx51-src as with other imx SOCs.

I'm mostly interested in the syscon part to be able to use regmap for
MIPI DSI here.
Patch is against next-20190114 plus Lucas "arm64: dts: imx8mq: move
watchdog nodes to correct location" but also applies to
https://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux.git/log/?h=imx/dt64
It will conflict with "arm64: dts: imx8mq: add GPC power domains" which
is not yet in any tree I've seen.

That's not true. The SRC is significantly different from the i.MX51
one. See series "[PATCH v4 0/3] Reset controller support for i.MX8MQ".
We generally don't add the DT nodes until at least the binding, better
yet the full driver, is upstream.

Lucas

I guess I got carried away by the parts I needed working and mostly
requiring the syscon part. So let's hold that off, thanks for the quick
reply.
