[PATCH v3 00/10] Fix up WCN6855 RFA power supply name

[PATCH v3 00/10] Fix up WCN6855 RFA power supply name

[Konrad Dybcio]

Commit 5f4f954bba12 ("dt-bindings: bluetooth: bring the HW description
closer to reality for wcn6855") renamed the supply representing the
VDD17_PMU_RFA leg to mention "1p8" instead.

While the supply's voltage is normally 1.8 V, the bindings should
reflect the actual naming of the pin. Moreover, almost all DTs define
the output as 1p7, so that ends up looking a little odd..

Ultimately, this is a "fake" regulator that is consumed for the sake
of DT sanity and this series is meant to bring uniformity and squash
checker errors.

The last patch fixes up a less-trivial warning.
sc8280xp-microsoft-arcata is left out because I don't know whether the
mounting of the chip is on-board or as an M.2-y card (although I would
guesstimate the prior).

Depends on the long-ready-for-the-merge series by Krzysztof (per-chip
bindings split of qualcomm-bluetooth.yaml), mentioned below

[PATCH v3 01/10] dt-bindings: net: bluetooth: qualcomm: Fix WCN6855 regulator names

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

Commit 5f4f954bba12 ("dt-bindings: bluetooth: bring the HW description
closer to reality for wcn6855") changed the vddrfa1p7-supply to 1p8
for whatever reason.

The schematics footprint for this chip definitely says 7 on the input
leg and the driver still expects 1p7. Bring it back.

Fixes: 5f4f954bba12 ("dt-bindings: bluetooth: bring the HW description closer to reality for wcn6855")
