[PATCH 0/4] Dove pinctrl fixes and DT enabling

[PATCH 0/4] Dove pinctrl fixes and DT enabling

[Sebastian Hesselbarth]

With other Orion SoCs moving to DT enabled pinctrl and gpio drivers,
now also move Dove to them. This patch set first fixes some issues
introduced during the first release of dove pinctrl and now. Then it
moves Dove to DT pinctrl and gpio and enables a gpio led pinhog for
CuBox.

This patch relies on a patch set for mvebu pinctrl taken through
Linus' pinctrl branch. As there is no other platform than Dove 
involved, I suggest to take it though Jason's tree to avoid any
further conflicts.

Axel Lin (1):
  pinctrl: mvebu: Fix dove_audio1_ctrl_set function

Sebastian Hesselbarth (3):
  pinctrl: mvebu: fix iomem pointer for dove pinctrl
  ARM: Dove: Convert to DT GPIO and pinctrl
  ARM: Dove: Add CuBox pinhog for led

[PATCH 1/4] pinctrl: mvebu: fix iomem pointer for dove pinctrl

[Sebastian Hesselbarth]

There has been a change in readl/writel to require registers
addresses marked as IOMEM(). This patch takes care of this and
also replaces ORing address offsets with adding them.

[Sebastian Hesselbarth]

From: Axel Lin <axel.lin@ingics.com>

When setting audio1 pinmux the bits in the corresponding registers
are not cleared. This fix first clears all bits and then sets the
required bits according to the selected function.

[PATCH 3/4] ARM: Dove: Convert to DT GPIO and pinctrl

[Sebastian Hesselbarth]

Following the ongoing conversion of Orion SoCs to DT, make use of
gpio and pinctrl drivers through DT. The main dtsi for Dove is prepared
to allow board specific descriptors to make use of pinctrl muxing.

[PATCH 4/4] ARM: Dove: Add CuBox pinhog for led

[Sebastian Hesselbarth]

SolidRun CuBox has a led on a gpio pin. As there is now DT pinctrl
support for Dove, make use of a pinhog to ensure the pin is set to
gpio.

Linus,

I am referring to patches for a pinctrl/mvebu subfolder. IIRC Thomas
posted that patch a while ago. Jason is currently sorting things out
for mvebu pull requests. I guess both can comment on your question,
as I don't fully understand it.

So what I mean is that the patches creating pinctrl/mvebu is in the
pinctrl tree, so if patches in the MVEBU tree depend on these,
then it must have pulled in a branch from pinctrl or applied the
same patches in that tree too (which is OK *sometimes*).

I know there has been some discussion between Arnd and Jason Cooper
(who handles the pull requests for the overall mvebu effort) about this
specific topic. I think the outcome of the discussion was that Jason
would have to see how much the rest of the mvebu stuff depends on this
pinctrl/mvebu change and will see with Arnd how to proceed. But it's
certainly better if Jason gives you directly feedback about this.

Yes, Thomas and Gregory informed me of the pinctrl dependency and said
they were using for-next from the pinctrl tree.  I've used that branch
to merge and build successfully.  Is that ok in practice or is there a
more specific branch I should pull in as a dependency?

Do not use for-next. That is a mix-down for the linux-next tree.

It is basically created like this:

git checkout for-next
git reset --hard fixes
git merge devel

fixes will be based on the latest release candidate and devel on
something older like -rc1, -rc2.

If you pull something in it must be from the devel branch.

The ebst idea is to take the last commit in the devel branch
that you need, so the last mvebu commit in that branch.
This is what the ARM SoC guys usually does.

So: git pull <pinctrl tree> devel
git log ...
<find the commit you need e.g 10930572>
git checkout -b my-new-mvebu-stuff 10930572

So you branch off where you have the deps you
need.

That way I can still reorder patches *above* that
commit (not that I should, but sometimes we discover
commits that are not bisectable and such exceptions).

The result can the be pulled into my tree or ARM SoC
or similar.

The above line broke the dtbs build target for dove_defconfig.  I have
removed it.  Please let me know if that is not the correct answer.  This
was the only occurence of 'clk' in arch/arm/boot/dts/dove* .

Are you sure you merged

 [PATCH 7/8] ARM: dove: switch to DT clock providers ?

This one clearly adds gate_clk in dove.dtsi. This patch was part of the
pull request:

Yes, so that's what I thought happened.  This would have made orion/dt
depend upon mvebu/everything.  It already had two other dependencies.
Not ideal.

The good thing is, the build is not broken.  Once v3.8-rc1 drops with
all of our stuff merged, I'll post a fixup patch adding this back in.

thx,

Jason.

It unfortunately means that Dove will be basically unbootable in
3.8-rc1, as the driver will not be clk_get()ing its gatable clock, and
the clock driver will disable it. Maybe we can just live with it, I
don't know.

Yes, I thought as much after I sent this reply.  Definitely a choice of
the lesser of two evils.  As long as we don't break the build or have
horrendous merge conflicts, I think it's tolerable.

Any one who is booting -rc1's is typically bug hunting.  This means
Sebastian, who has been CC'd on all of this.  I don't want to rely on
this in the future, but doing it once due to the circumstances is
something I'm comfortable answering to.

thx,

Jason.

Jason,

sorry for the late answer. I merged all pull reqs in the order posted
on top of latest linux/master. Thomas is right, removing the clk_gate
from pinctrl potentially could have broken boot on dove. I tried it and
it _does_ boot, because the clk used by pinctrl is optional in pinctrl-dove
and there is no pinhog/device touching the register clocked by the clock.

As soon as I 'cat pinconf-groups' in debugfs, the register is read and
my cubox hangs as expected.

So, finally a fixup patch for 3.8-rc1 is ok for me.

Thanks for merging all the patches!

Sebastian

[PATCH 1/2] ARM: Dove: Add pinctrl clock to DT

[Sebastian Hesselbarth]

During merge of the mvebu patches a clock gate for pinctrl was
lost. This patch just readds the clock gate.

[PATCH 2/2] pinctrl: mvebu: make pdma clock on dove mandatory

[Sebastian Hesselbarth]

With the ability to pass clocks through DT, now make the pdma
clock of dove pinctrl mandatory. Otherwise, pinctrl will hang
the system when accessing some registers.
