[PATCH 1/2] ARM: dts: r8a7792: add PLL1 divided by 2 clock

[Simon Horman]

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

Despite the fact that QSPI clock has PLL1/VCOx1/4 clock as a parent, the
latter hasn't been added to the R8A7792 device tree. This patch corrects
that oversight.

[PATCH 2/2] ARM: dts: r8a7792: remove ADSP clock

[Simon Horman]

From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

Simon Horman told me that R8A7792 has ADSP clock based on an incorrect
table in the most recent R-Car gen2 manual. But when I received that manual
I discovered that this is false: R8A7792 is the only Gen 2 SoC that doesn't
have ADSP at all.  Accordingly remove the ADSP clock from DT for the
r8a7792.

Thanks!

I have queued up another fix for v4.8 since sending the above to you.
This time it is an SoC (C-code) rather than a DT fix. I am wondering
if you could offer guidance on:

* If you would prefer me to split fixes out into separate (DT, SoC, ...)
  branches? If so is that until around rc1 when everything has been
  merged into the forthcoming release and thereafter you would prefer
  a single fixes branch?

* What pace you would like me to send fixes. I guess it depends on
  where we are in the cycle. Currently I put the changes in next and
  send what I have about once a week (or not if there are none :).

Typically there are very few fixes. But as I already have 3 for v4.8,
including those in this pull request, I get the feeling a few more could
emerge before v4.8 is released.

I prefer a separate fixes branch. It's fine for all other branches
to be based on top of this branch so you have a working baseline
for testing.

I'd say don't wait longer than a week before forwarding bugfixes.
If you find something urgent, just send that right away along with
whatever less urgent patches you have accumulated.

It's possible we won't merge it right away as we might all be busy
for a couple of days, but in the worst case that means you send
another fixes pull request that is a superset before we have merged
the first one.

Is some sort of minimal base for the fixes branch desired?
If should the base be a merge of all the tags you have pulled for v4.8?

Currently I have DT fixes and SoC fixes which depend on
respective tags that have been accepted for v4.8.

It's hard to make those one branch without doing your own merge. You
can't take a merge out of our for-next branch as a base, since those
aren't stable.

Wait for our merges to go into Linus' tree, then use his last merge
commit as the base (before -rc1 is out).
