Of course we thought about it. But as you are dealing with different
SoCs at a time, we also have to care about some more SoCs than just
Dove. And, of course, we also run out of spare time to prepare proper
patches over and over again. I really /know/ that if you send patches,
they are well thought and well tested, so I basically postpone work
on that if I know you are working on it.
My current idea of PMU register space is to have a DT provided regmap
but again, there are patches floating around but currently that regmap
helpers are still WIP. FWIW, if you look at dove pinctrl, we did a
last-minute patch for the PMU regs - just because you mentioned a
concern, so we really care about your opinion. The fact that it is not
solved is pure lack of time.
Nothing has changed on the PMU patches since I posted them, because
they're based on 3.15 and there's been no changes there.
I offered to deal with mainlining them end of April, you never replied.
I know that if you dislike something you answer, but it is hard to tell
if silence means agreement.
I am not going to waste any time preparing patches just to get a NAK.
Exactly that increasing amount of (valuable) patches makes it more
and more difficult for you and us to reproduce any issues. All I am
asking for is: if you don't push that branch for good reason, try to
split off at least some patches. Hunting issues like the HDMI thing
with 250 patches off, really isn't going to work well.
Right, so what I have against mainline right now in my tree is:
* two SPI patches, which have been taken by Mark
* one long term core ARM patch adding optimised memset/memcpy IO operations
* the PMU stuff
* BMM (already published in git form)
* Vmeta (already published in git form)
* ASoC cleanup patches, which Mark took last week.
What isn't visible is the stuff which converts Armada DRM to component
support, along with the TDA998x driver (and it sounds like the TI LCDC
people may end up blocking that effort). This is necessary to convert
it to DT support. However, this depends on the component helper, and
that's where there's a blocking problem.
I sent out a bunch of patches last week, with a request for help from
the Exynos people. So far, that has only attracted one relatively minor
comment from the iMX people. I can't move forwards with the Armada
DRM until this is sorted. Neither can I move forward with the TDA998x
driver.
As for the ASoC stuff which you avoided commenting on, let me repeat
that _that_ stuff is now totally dead and can /never/ be merged into
mainline without breaking the existing ASoC kirkwood support. In
that case, it's not like I wasn't sending the patches out, because
I had been... so everyone was aware of what was going on there,
but I guess converting stuff to DT in ways that totally fuck over
other patches is what now happens in the kernel.
If you are talking about "Kirkwood ASoC updates", you got a Tested-by
from Andrew even before I read your patches. And besides, just because
I am interested in Dove does not mean I just swallowed the whole Linux
API knowledge. I simply avoided commenting on it, because there is
/nothing/ I can add to it.
Really, I know you do dig down to the bottom of every subsystem you
are working with but I simply cannot. Just because I don't have the
time for it.
What I think you're missing is that for those of us who want to have
a platform fully supported, the choice has been non-DT until relatively
recently. We're now at the point where the DT support on Dove has
matured to the point where it's relatively easy to end up with a fully
functional (but not necessarily bug free) setup with DT. It's at the
sweet spot where you can switch between DT and non-DT and preserve
that functionality... but as soon as we get there we want to rip out
the old stuff.
Oh, ok.. you think it is "me" and "us"? It is you who actually want to
use Dove and me just wanting a DT representation for it?
It is not my fault that your patches are blocked by others. I can offer
help to track down the issue, but I am not going to be your scapegoat.
Let me put that another way: it's at the point where those of us who
have been using non-DT support can start moving the remaining drivers
over to a DT environment without any functional loss.
What I'm trying to get you to understand is that leaving the old stuff
behind for a little while longer is beneficial - while those who have
been running crippled DT based setups for the last year don't care
about having full support, there are those who do.
Ok, let's have mach-dove for a little longer, fine with me.
Of course, there's another solution to this. I stay with my present
3.15 kernel for ever. That basically bars me from sending any further
patches. It also means that I stop maintaining TDA998x and Armada DRM,
and you will have to take those over, which means you get the additional
workload from those. Is that what you really want?
What I really want is to stop that blackmailing with giving up on
sending patches. It will be a huge loss if you do and many have said
that in the past.
If it is really me who upsets you because you feel I am blocking your
patches, just ignore my comments. Jason will happily pick them up
just because you signed them off.

The Cubox is the /only/ ARM platform I have which is a capable media
player, and I'm trying not to have it screwed by this kind of crap.
