[GIT PULL] Renesas ARM Based SoC DT Timers Updates for v3.17

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these Renesas ARM based SoC DT Timers updates for v3.17.

This pull request is based on a merge of the following to provide
all dependencies and try to eliminate conflicts. It turns out the changes
in this pull requests are a nexus for dependencies due to modifying DT,
SoC, board and recently moved header files as well as requiring driver
changes.

* The clockevents/renesas-timers-dt branch of Daniel Lezcano's tree.
  He has indicated that this branch has stable commit ids and will
  be included in v3.17. Olof and arm at kernel.org were CCed on the
  thread where he, Laurent Pinchart and I discussed the use of that branch.

  The clockevents/renesas-timers-dt's branch is in turn based on v3.16-rc3.

* "Third Round of Renesas ARM Based SoC DT Updates for v3.17",
  tagged as renesas-dt3-for-v3.17, which I have sent a pull request for.

* "Renesas ARM Based SoC Clock Updates for v3.17",
  tagged as renesas-clock-for-v3.17, which you have merged
  into next/soc

* "Second Round of Renesas ARM Based SoC soc-cleanup Updates for v3.17",
  tagged as renesas-soc-cleanup2-for-v3.17, which you have merged
  into next/cleanup.

* "Third Round of Renesas ARM Based SoC r8a7779 Multiplatform Updates for
  v3.17", tagged as renesas-r8a7779-multiplatform3-for-v3.17, which
  you have merged into next/soc

* "Renesas ARM Based SoC Boards Updates for v3.17",
  tagged as renesas-boards-for-v3.17, which you have merged
  into next/boards

* "Third Round of Renesas ARM Based SoC Updates for v3.17",
  tagged as renesas-soc3-for-v3.17, which you have merged
  into next/soc

[PATCH 7/8] ARM: shmobile: r7s72100: Add MTU2 device to DT

Add the MTU2 counter to the r7s72100 device tree and make it disabled by
default.

[PATCH 8/8] ARM: shmobile: genmai-reference: Enable MTU2 in device tree

[Simon Horman]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

No more device needs to be added from platform code when booting the
reference platform, move MTU2 registration from setup-r7s72100.c to
board-genmai.c and remove the now empty r7s72100_add_dt_devices()
function.

As the genmai_add_standard_devices() function is now identical to the
default init_machine implementation, remove it as well.

Ok, this branch definitely contains a lot more than this. For dependent
external branches such as clocksource, we still prefer to see a pull request so
that we can merge in the dependency and get a clean diffstat when we do the
merge of your branch, otherwise it gets awkward to compare that what we're
getting is what you thought you sent (which is one of the things we check on
merges).

Please regenerate this pull request as appropriate.

Hi Olof,

FWIW, I believe that that the diffstat between
5c174afd407acc7a90701900b279578151bc007f and
9394af4314554d15762585a3464cefaa2e6d0420 is what was included in the
pull-request. But I guess that all the merged-in branches are hampering
your verification process.

Would it help if things were arranged as follows?

1. Use the clocksource branch as a base and then;
2. Merge in each of my branches (the ones listed above) and then;
3. Add the patches on top

Hi Olof,

I'd value your feedback on this if you have a moment.

Ah, sorry. Got lost in the other pull requests.

So there's nothing wrong per se with the way you arranged it, even
though it is more convenient for us from a review perspective to get
merges of branches at the tips of previous branch heads (i.e.
tags/merge requests). It just makes it easier to spot "Oh, that side
of the merge is from this branch that we've already reviewed", etc.

For generating pull requests for these complex merges, what we do when
sending stuff upstream is that we generate a dummy merge and
"manually" (through a script) generate the diffstat and shortlog from
that. Git can get confused about what is actually the merge-base
otherwise, which is what happened in this case for you.

[GIT PULL] Renesas ARM Based SoC DT Timers Updates for v3.17

[Simon Horman]

Hi Arnd,

I understand from Olof that you are handling pull-requests at this time.
I would like you to consider this one in light of the extra
information that I have provided below.

This should have been :

         * "Third Round of Renesas ARM Based SoC Clock Updates for v3.17",
	   tagged as renesas-clock3-for-v3.17.

	   I somehow forgot to tag that branch and send a pull-request.
	   I have done so now.

Thanks. I believe that the cause of this problem is the missing
renesas-clocks3-for-v3.17 pull-request that I noted above.

As discussed off-list, I think that with that taken into account this
pull-request should match its description.
