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

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

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).
OK. Either README.cip or " by including more information on the reference hardware and test information on CIP wiki." as suggested by Nobuhiro.

I guess we should really have README file in the tree, explaining
potential compatibility issues and anything unusual happening in the

* -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

* -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?
