[PATCH v3 0/3] dts: meson: add clock controllers input clocks

[PATCH v3 0/3] dts: meson: add clock controllers input clocks

[Jerome Brunet]

This patchset is the first step that needs to be done so the
amlogic clock controllers properly claim their input clocks
through DT instead of relying on fixed names.

I'll be waiting for this hit mainline before sending the related
driver changes.

Changes since v1: [0]
- add clock-names for the main clock controller

Changes since v2: [1]
- add more inputs for the gx family external 32k references

Stephen,

Since I made some changes here, I did not pick your previous
Reviewed-by tag, in case you did not agree with this version.

Cheers

Queued for v4.21 (branch: v4.21/dt64) with Stephen's tags.

nit: $SUBJECT on this cover letter is missing arm64 prefix (v2 had it)
and, some lazy maintainenrs like me are starting to rely on the new new
patchwork-bot which will auto-superseed series when a new version is
posted, but that relies on matching subjects.
