 The cover letter explains that the series is rebased onto Mauro's
 master with Kukjin's branch merged. The latter does contain
 the exynos5433.dtsi. That said, yes, taking patches 1-3 in
 media subsystem and leaving DT patch to someone else is the
 way to go.

Yes right, as Krzysztof commented, the pull-request has been rejected by
arm-soc even I explained it has been tested on smdk5433, because it will
not be compiled without relevant board DT file. And I've rebased when
new -rc1 released until 4.3...because Chanwoo said at that time that
regarding DT file will be submitted but not yet...

To be honest, I'm not sure I can keep the exynos5433 changes for v4.4 in
my tree at this moment...

Could be...hmm...

 Although Kukjin picked Exynos 5433 ARM64 patches but they were not
 accepted upstream by arm-soc. He rolled it for few releases but:
 1. Reason for not accepting by arm-soc was not resolved - there is no DTS.
 2. Kukjin did not rebase the branch for 4.4... which maybe means that he
 wants to drop it?
 3. Anyone (but me...) can send Galaxy Note4 (Exynos5433) DTS file based
 on sources on opensource.samsung.com. The DTS there is for 32-bit but it
 can be probably easily adjusted for ARM64.

Thanks for your handling the exynos5433 patches on your tree.
But, I might not send the board DTS file for Exynos5433 SoC right now.
If I send the board DTS patches in the future, I'll send both board dts patches
and Exynos5433 SoC patches again.

 This dtsi file doesn't exist in the media-git tree. What is the story
 here?

 Should this go through a different subsystem?

 I think the media subsystem can take patches 1-3 and whoever does DT
 patches can
 take this patch, right?

I already explained. There is no DTS, so the pull request was rejected
(pull request for v4.0 I believe).

It was not about adding drivers for 5433's clocks/phy/pinctrl etc. It
was about DTS.

Exynos5433 support is being incrementally merged (clocks, drm, phy,
pinctrl, thermal and tty support is already in upstream or -next).

I don't know why DTS changes got stuck in Kukjin's tree (Kukjin,
could you please explain?) but I think that this shouldn't not stop
us from continuing Exynos5433 upstreaming effort.

The TM1 device (Z3) is based on a Qualcomm 64-bit SoC. The $subject
patch adds support for a standalone JPEG codec IP block of Samsung
Exynos5433 SoC, which can be found for instance in Galaxy Note4.
Perhaps someone else can provide more details regarding the TM1's camera
status.

I've checked. It does compile with COMPILE_TEST.

No, it does not. It is a rather simple mem2mem device.

I'm ok with such strategy, provided that the new driver builds fine with
COMPILE_TEST without the need of the dtsi patch.

Please also notice that, if the driver uses MC, it has to wait for
the MC next gen support to be merged, and may need to be rebased, due
to a few changes at the MC internal APIs: one function got renamed
(the function that create links between two pads) and we're now using
lists for links (that will only affect the driver if it has its own
graph traversal routines).

Btw, I just got a Samsung TM1 device, with seems to be using an arm64
SoC. Is this driver providing support for its camera?

Mauro.
