You are right, I first thought I need to add you, then I thought you
are reading the low traffic list anyway. 
Sorry for the trouble.

I will do in the future. Do you thing following patch would be okay
to commit to make changes to architecture specific parts
more formal?

Is the commit okay or do I need to revert it?

@Max: Okay to add you as Xtensa maintainer?

Applied "ASoC: dwc: Add irq parameter to DOCUMENTATION" to the asoc tree

[Mark Brown]

The patch

   ASoC: dwc: Add irq parameter to DOCUMENTATION

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: dwc: Add PIO PCM extension

A PCM extension was added to I2S driver so that audio
samples are transferred using PIO mode.

The PCM supports two channels @ 16 or 32 bits with rates
32k, 44.1k and 48k.

Although the mainline I2S driver uses ALSA DMA engine the
I2S controller can be built without DMA support, therefore
this is the reason why this extension was added.

[GIT PULL] drm/arcpgu: Make ARC PGU usable on sim platforms

[Alexey Brodkin]

Hi Dave,

Please pull this mini-series that allows ARC PGU to be used on simulation
platforms like nSIM OSCI (AKA Linux Virtual Platform) or ARC VDK.

The series was published for review here
https://lists.freedesktop.org/archives/dri-devel/2016-June/110647.html

It is based on today's "drm-next" branch.

Best regards,
Alexey

I just do drive-by comments on driver submissions, review/merge rules are
up to each driver maintainer mostly. But for the warm and fuzzy feeling
I'm happy to ack ;-)

Patches for ARC

[Alexey Brodkin]

Hi Waldemar,

Just saw that new change for ARC ("arc: use generic lowlevellock",
http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/?id=1b49dc96d103e0151fee290d55cea55aa12c906d).

Even though this is very nice to see fixes and improvements done by people
outside Synopsys IMHO it still makes sense to add SNPS people in the loop so
we may review submitted patches.

So could you please first get an Ack from either Vineet (in Cc) or me before
committing stuff for ARC? Alternatively just Cc 
linux-snps-arc@lists.infradead.org.

Again I'm very happy with uClibc-ng and appreciate a lot all your efforts
and to make uClibc-ng more robust let's review stuff together.

Also it was hard for me to find a relevant patch on the mailing list
because I was expecting patch to be sent via git "send-email" (which I think
should be a standard way for patch submissions in uClibc). Only going through a 
relevant
thread for ARM I found a message with attached files.

-Alexey
