I'm happy to apply any Backlight patches which have either Bryan or
Jingoo's Ack, as they are the reviewers for the BL subsystem.

* [PATCH] OMAPDSS: move 'compatible' converter to omapdss driver
From: Tomi Valkeinen @ 2014-05-22 12:10 UTC (permalink / raw)
To: linux-omap, linux-fbdev, Sebastian Reichel, Tony Lindgren
Cc: Javier Martinez Canillas, Tomi Valkeinen
In-Reply-To: <1400141136-25358-1-git-send-email-tomi.valkeinen@ti.com>
Move the panel/encoder driver compatible-string converter from
arch/arm/mach-omap2/display.c to omapdss driver. That is a more logical
place for it, as it's really an omapdss internal hack.
The code is rewritten to follow the video node graph, starting from
omapdss. This removes the need to have the device compatible-string
database.

Tony, this series will get delayed until 3.17, but I'd like to merge the
HDMI DMA channel changes to omap4/omap5.dtsi already to 3.16. They are
patches 13 and 15.
Those are very trivial, but I'd rather have acks from you for all the
.dts changes I'll be sending.

Hmm, what's the syscon stuff about? Looks like it's required, but the DT
documentation patch doesn't mention it at all.

I don't know. All options sound somewhat bad to me, except if it's clear
nobody uses the old driver.
Anyway, it's rather late for 3.16. I'd like the removal of the old
driver to sit in the linux-next for a while.
Would it be possible to add the new driver along the old driver, and use
the new driver only for the boards you have, and for boards for which
it's clear the the old driver is not working? This could be merged for 3.16.
It's not so nice to have two drivers for the same hardware, but in this
case maybe that's not an issue. The old driver doesn't support DT, so no
conflicts there, and for non-DT the driver names seem to be different.
For 3.17, we could remove the old driver, and push that change to
linux-next right after the 3.16 merge window has closed.
Or, if you're fine with it, we can also delay adding the new driver to
3.17, and do both right after the 3.16 merge window has closed. I
personally like this most, so that we have both removal of the old and
adding the new sitting in the linux-next longer, but you might possibly
want the new driver in sooner.
Maybe I'm being overly cautious here, but as I don't have any idea about
the driver and its users, I rather be too cautious than not.

Hmm, why is that not possible with multiplatform support? What do you
mean with multiplatform support here?
While the drivers would handle the same device, if they have different
names then they are different device drivers from Linux's perspective.
Why can't one board use the old driver, and an other board use the new
driver?

There would be no one using the driver in 3.16, then, right?

I'm a bit unclear what the multiplatform stuff means here, but yes,
generally sounds ok.
But I don't want to make this more difficult for you than it needs to.
As I said, I'm fine with the current patches, if we skip 3.16 and get
them to linux-next right after the merge window. If nobody would use the
new driver in 3.16 anyway (in your proposal above), would this be the
easiest way?

We are migrating all ARM platforms to allow building them into a single
kernel. However, that means that device drivers cannot access platform
specific header files any more and have to get hardware information from
DT or through platform data. The existing driver however uses mach/hardware.h.

Ah, I see. So the problem is not with two different drivers for the same
hardware device as such, but that in this case the older driver just
doesn't play well with multiplatform.

If the old driver doesn't even play well with multiplatform, and is thus
blocking moving the SoC to multiplatform, I'd just get done with it in
one go.
So I would recommend pushing the new driver and the removal of the old
one for 3.17, and having those changes in linux-next right after the
3.16 merge window.
Is that ok?

OK fine with me:

* [PATCH 00/13] Fix OMAP4+ HDMI audio

This patch set fixes the resource sharing problems between
omap-hdmi-dai driver and OMAPDSS HDMI driver. It does it by
registering the OMAP HDMI audio related ASoC drivers from OMAPDSS HDMI
driver. Platform data structs have been added for omap-hdmi-dai and
omap-hdmi-card drivers to pass the information and resources from
OMAPDSS HDMI driver.
The idea of this patch set is to fix HDMI audio for the next release
after it got broken by OMAPDSS DT changes. It does not mean that I
have abandoned the patch set that integrates the omap-hdmi-dai driver
into OMAPDSS HDMI driver. The OMAPDSS side of those patches just had
some dependencies to the recent ASoC side patches that would have
caused problems in the next merge. I'll mail a revised and rebased
version of those patches soon.
Best regards,
Jyri
