[PATCH 0/3] ARM: dts: aspeed: Deprecate g[45]-style compatibles

[PATCH 0/3] ARM: dts: aspeed: Deprecate g[45]-style compatibles

[Andrew Jeffery]

Hello,

Joel and I decided that going forward we're not going to name compatibles along
the lines of SoC generations, so discourage any further attempts by removing
the remaining instances.

It's probably best if we push the three patches all through one tree rather
than fragmenting. Is everyone happy if Joel applies them to the aspeed tree?

Cheers,

Andrew

[Andrew Jeffery]

Use the SoC-specific compatible strings instead.

Sorry no. :( Was I too trigger-happy?

Usually I take Rob's ACK as authoritative for anything under
Documentation/devicetree but if you have concerns about the
patch from an MFD point of view I will revert it pending further
discussion.

If you are sure it will not collide with parallell work in the
pinctrl tree, yes.
Acked-by: Linus Walleij <linus.walleij@linaro.org>

(If it does collide I'd prefer to take the pinctrl patches and fix the

Fair enough, I don't know the answer so I'll poke around. I don't really mind
where the series goes in, I just want to avoid landing only part of it if I split it up.

Okay, it currently conflicts with my cleanup-devicetree-warnings series.

Joel, do you mind if Linus takes this series through the pinctrl tree, given
the fix to the devicetrees is patch 1/3?

It depends if you plan more changes to that part of the device tree
this merge window :)

Linus, perhaps the safer option is for me to take 1/3 through my tree
and you can take the rest through yours?
