[PATCH v3 0/5] powerpc: apm82181: adding customer devices

[Christian Lamparter <chunkeey@gmail.com>]

Hello,

I've been holding on to these devices dts' for a while now.
But ever since the recent purge of the PPC405, I'm feeling
the urge to move forward.

The devices in question have been running with OpenWrt since
around 2016/2017. Back then it was linux v4.4 and required
many out-of-tree patches (for WIFI, SATA, CRYPTO...), that
since have been integrated. So, there's nothing else in the
way I think.

A patch that adds the Meraki vendor-prefix has been sent
separately, as there's also the Meraki MR32 that I'm working
on as well. Here's the link to the patch:
<https://lore.kernel.org/linuxppc-dev/20200822154045.16036-1-chunkeey@gmail.com/>

Now, I've looked around in the arch/powerpc for recent .dts
and device submissions to get an understanding of what is
required.
From the looks of it, it seems like every device gets a
skeleton defconfig and a CONFIG_$DEVICE symbol (Like:
CONFIG_MERAKI_MR24, CONFIG_WD_MYBOOKLIVE).

Will this be the case? Or would it make sense to further
unite the Bluestone, MR24 and MBL under a common CONFIG_APM82181
and integrate the BLUESTONE device's defconfig into it as well?
(I've stumbled across the special machine compatible
handling of ppc in the Documentation/devicetree/usage-model.rst
already.)

Cheers,
Christian

Note:
If someone has a WD MyBook Live (DUO) and is interested in
giving it a spin with 5.8. I've made a:
"build your own Debian System" sort of script that can be
found on github: <https://github.com/chunkeey/mbl-debian>
(the only remaining patch hack is for debian's make-kpkg crossbuild)

Furthermore, the OpenWrt project currently has images for
the additional apm82181-based devices:
 Cisco Meraki MX60(W) - Needs DSA for the AR8327
 Netgear WNDAP620/WNDAP660 - (Could be next)
 Netgear WNDR4700 - Needs DSA for the AR8327

Note2: I do have a stash of extensive APM82181 related documentation.
