[cip-dev] [PATCH 4.19.y-cip 01/12] arm64: dts: renesas: r8a774a1-hihope-rzg2m[-ex/-ex-idk-1110wr]: Rename HiHope RZ/G2M boards

[Biju Das]

[-- Attachment #1: Type: text/plain, Size: 5421 bytes --]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit a80f301ea69e76f10099626986b4674c6f990a15 upstream.

The existing DTS files for HiHope RZ/G2M boards are for Rev.2.0 version
so reflect the same for the DTS file names so that the existing naming
convention can be used for Rev.3.0/4.0 boards.

While at it also added a comment about switch SW43 to be OFF for pciec1
to be activated.

[cip-dev] [PATCH 4.19.y-cip 03/12] arm64: dts: renesas: hihope-common: Separate out Rev.2.0 specific into hihope-rev2.dtsi file

[Biju Das]

[-- Attachment #1: Type: text/plain, Size: 6751 bytes --]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit 99167613db6e439d877131e1fbe617e4420b954f upstream.

Separate out Rev.2.0 specific hardware changes into hihope-rev2.dtsi
file so that hihope-common.dtsi can be used by all the variants for
RZ/G2M[N] boards.

LED node names have been updated according to Rev.4.0 schematics.

[cip-dev] [PATCH 4.19.y-cip 04/12] arm64: dts: renesas: Add HiHope RZ/G2M[N] Rev.3.0/4.0 specific into common file

[Biju Das]

[-- Attachment #1: Type: text/plain, Size: 4173 bytes --]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit faf1ce7f1ef65af81bd85fe9c70950571cd70b19 upstream.

Rev.3.0 and Rev.4.0 are identical and can be identified by using GP5_19
and GP5_21.

	Rev		GP5_19	GP5_21
	==============================
	Rev.3.0		0	0
	Rev.4.0		0	1

This patch creates hihope-rev4.dtsi file with
Rev.3.0/4.0 specific changes for HopeRun HiHope RZ/G2M[N] boards.

[cip-dev] [PATCH 4.19.y-cip 11/12] arm64: dts: renesas: Add HiHope RZ/G2N Rev2.0/3.0/4.0 board with idk-1110wr display

[Biju Das]

[-- Attachment #1: Type: text/plain, Size: 3349 bytes --]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit 667175f5029c5f6ec7a72811fc6b14c33d252286 upstream.

The HiHope RZ/G2N variants are advertised as compatible with panel
idk-1110wr from Advantech, however the panel isn't sold alongside the
board. New dts's, enabling the lvds node to get the panel to work with
all the HiHope RZ/G2N variants.

I'm pretty sure this is not the real diffstat.

Let me go through the changes. One concern: you are renaming dts
files. New names make a lot of sense, but that will likely break the
users, including our test infrastructure, no?

Re: [cip-dev] [PATCH 4.19.y-cip 01/12] arm64: dts: renesas: r8a774a1-hihope-rzg2m[-ex/-ex-idk-1110wr]: Rename HiHope RZ/G2M boards

[Pavel Machek]

[-- Attachment #1.1: Type: text/plain, Size: 787 bytes --]

Hi!

Ok, so this is anti-social:

> -dtb-$(CONFIG_ARCH_R8A774A1) += r8a774a1-hihope-rzg2m.dtb
> +dtb-$(CONFIG_ARCH_R8A774A1) += r8a774a1-hihope-rzg2m-rev2.dtb

This renames dts away, but at the end of series, new dts is created
with the r8a774a1-hihope-rzg2m.dts name, but this time it is for rev4
(not rev2) board.

So... people with rev2 boards and existing build script will get rev4
dts.. without any error.

Would it be better to always require explicit revision in dts/dtb
name?

Tests are running at
https://gitlab.com/cip-project/cip-kernel/linux-cip/tree/ci/pavel/linux-test
.

Best regards,

								Pavel

Yes, that is true. But if you agree, We need to use our latest/greatest SoC/board as the main SoC/Board and rest are with explicit revision in dts/dtb .

The existing users can read gpio values to differentiate rev2.0/rev4.0 boards and load the appropriate dtb/execute the test script accordingly.

>

This is our thoughts on this.  We need to use our latest/greatest SoC/board as the main SoC/Board and rest are with explicit revision in dts/dtb .
So this is inline with your suggested comment.

Please share your comments, I may be wrong.

Cheers,
Biju

Technically yes, it would cause problems. However this seems to be the way of doing things upstream.
I guess upstream is a bit different though as users would expect such things when upgrading Kernel versions.
For SLTS perhaps users wouldn't expect to see such changes? It may be easier to keep things in sync with upstream though.

FYI the "rev4" dts does actually boot on "rev2" boards. It's just that some functionality like WiFi/BT and audio won't work.
(and the rev2 dts will boot on rev4 boards)

lab-cip-renesas uses rev4 boards, so from a CIP testing point of view there will be no issues. 

Kind regards, Chris

I believe it would be better to always use explicit revision in these
cases; anything else is fairly confusing, as kernel update breaks your
setup (aka a regresssion).

Now, if -rev2 had few copies, and people really have -rev4, there will
not be much breakage. But imagine if rare -rev5 is released in future...

But mainline already made the choice. I'd just prefer not making same
choice in future.

Now, what to do here? One way would be to apply a series, but add a
README.cip file explaining incompatible change (and any future stuff
people need to know).

Best regards,

								Pavel

Yes, it is upstream problem, and should be fixed upstream.

And no, not even upgrading kernel versions should break anything.

Ok, good to know, it seems -rev2 boards are kind of rare?

I guess we could create "README.cip" explaining such non-standard
issues, and mention it in release changelog.

Or I think we can do this by including more information on the reference hardware
and test information on CIP wiki.

OK. Either README.cip or " by including more information on the reference hardware and test information on CIP wiki." as suggested by Nobuhiro.
Please let us know, How do we want to proceed?

I guess we should really have README file in the tree, explaining
potential compatibility issues and anything unusual happening in the
tree. I went through old changelogs, and collected these for 4.19
tree:

* -cip3: MDS sampling vulnerability fixes

This release includes many CVE fixes including MDS (Microarchitectural
Data Sampling: CVE-2018-12130, CVE-2018-12126, CVE-2018-12127,
CVE-2019-11091). These fixes were more extensive and harder to review
than usual for -stable tree.

* -cip9: m57621-mmc driver was removed

m57621-mmc driver was removed due to uncertainty about its licensing.

* -cip34: Support for Renesas RZ/G2[MN] revision 4 board

In -cip34, support for revision 4 of the board was merged. After the
merge, r8a774a1-hihope-rzg2m*.dtb files are suitable for revision 4 of
the board; if you want to produce dtb files for revision 2 of the
board, append -rev2 to the file names.

---

Does that sound ok?

Best regards,
								Pavel

Yes, It looks good to me.
