Is there a DTSI change part of this patch?  I was going to try to test
it, but  I am not seeing a change to the imx8mm.dtsi, and I am not
sure where to put the node.

There are in fact quite a few other pieces you need to have in place,
this patchset in itself is not particularly useful, it is just infra for
the LCDIF and MIPI DSIM block control. You might want to wait until they
all land in next and test that result.

I have several patches in place, the GPCv2, this block driver,
enabling GPU DT node, I'm also working on the DSIM patch you posted.
I was hoping to test them all together and reply to the various
threads with tested-by.  I also want to get my device tree stuff ready
on the beacon boards so when everything lands, I can post DTS updates
to enable the LCDIF, DSI, and the HDMI bridge.

If you have a repo somewhere that has all these combined, I can just
work on the final layer to enable the device tree plumbing on my
board.  I just need the imx8mm.dtsi changes for this, DSIM, and the
LCDIF so I can finish the task.

On that note, I also have a i.MX8M Nano board which is similar to my
8MM.  If I understood the 8MM clock block driver better, I hope to
adapt your changes for the Nano too.  Once the GPCv2 driver is
accepted, I was also going to look at updating it to support the Nano
as well which also has the same DSIM and LCDIF as the 8MM as well and
a better GPU than the Mini but lacking the VPU.

I don't have a branch, but I sent you the collected patches off-list.

I would also be interested in the patch collection for BLK_CTL, DSIM,
etc. Marek, would you mind sending me those, too?

Adam, did you already set up a branch and do some tests with the full stack?

Frieder,

I have been monitoring some of the activity on the BLK_CTL.  It seems
like there is some disagreement on how to connect the power domain
controller with the BLK_CTL.  Someone reported that it causes a hang
on the 8MP, so until that gets resolved, I doubt we'll be able to use
the display system.  Some of the DSIM changes happening are being
pushed back for further changes, so it seems like having the full
integration might be a while.

I have pulled all the latest patches, including Marek's off-list patches 
together in one branch based on v5.10-rc7 [1] if anyone is interested.

I added some fixes on top, that I needed to get my display behind 
another Toshiba DSI-DPI bridge working. Those are probably not 
upstreamable at all and need further investigation.

I'm hoping to reply to the individual threads for more feedback. I see 
that there are some blocking issues, but we hopefully get them resolved 
somehow.

Thanks
Frieder
