[00/14] ARM: dts: realtek: Introduce syscon

Message

Andreas Färber Dec. 2, 2019, 6:21 p.m. UTC

Hello,

This patch series factors out system controller multi-function device nodes
for CRT, Iso, Misc, SB2 and SCPU Wrapper IP blocks.

It was inspired by my SoC info RFC, as discussed in its cover letter [1].

Goal of DT is to describe the hardware, and in previous patches we've already
introduced Realtek's r-bus as node layer. The next step here is to model
multi-function blocks as nodes. In order to cope with 80-character line limit,
child nodes are added via reference rather than in-place.

Also included is a patch adding a reset constant for the SB2 block added.
We may need to follow up with bindings adding compatibles, clocks and resets.

This series is based on my RTD1195 v4 [2] (except for reset, rebased here),
my RTD1395 v2 [3] and James' modified RTD1619 v3 [4].

The irq mux series v5 [5] has been rebased onto this series, v6 to be sent.
The SoC info RFC series [1] is still being updated, v2 to be posted later.

Latest experimental patches at:
https://github.com/afaerber/linux/commits/rtd1295-next

Have a lot of fun!

Cheers,
Andreas

I'm waiting for your Acked-by of the blocks & numbers in these patches. 
Other Realtek engineers are also invited to respond, of course.

Thanks in advance,
Andreas

I have reviewed these patches.

Thank you for your contribution.

Thanks - does anything need changes in patch 01 or is that ack'ed, too?

Regards,
Andreas

No further response, so all (incl. 01/14) applied to linux-realtek.git:

https://git.kernel.org/pub/scm/linux/kernel/git/afaerber/linux-realtek.git/log/?h=v5.6/dt

Should there be anything wrong with 01/14, just send a follow-up patch.

Regards,
Andreas
