Subject: [PATCH v4 0/5] dts: qcom: Use labels with generic node names for ADC channels
Date: Mon, 10 Apr 2023 22:29:12 +0200	[thread overview]
Message-ID: <20230410202917.247666-1-marijn.suijten@somainline.org> (raw)

As discussed in [1] it is more convenient to use a generic `channel`
node name for ADC channels while storing a friendly - board-specific
instead of PMIC-specific - name in the label, if/when desired to
overwrite the channel description already contained (but previously
unused) in the driver [2].

The same `channel` node name pattern has also been set in
iio/adc/adc.yaml, but this generic binding is not inherited as base for
qcom,spmi-vadc bindings due to not having any other generic elements in
common, besides the node name rule and reg property.

Replace the .* name pattern with the `channel` literal, but leave the
label property optional for bindings to choose to fall back a channel
label hardcoded in the driver [2] instead.

Changes since v3:
- Switch generic node name to `channel`, matching iio/adc/adc.yaml;
- Besides switching arbitrary names to `channel`, now also rename all
  existing `adc-chan` names to `channel`, including ARM tree;
- Rebase on next-20230406 and apply rename to newer PMIC files.

v3: https://lore.kernel.org/linux-arm-msm/20230201204447.542385-1-marijn.suijten@somainline.org/T/#u

Changes since v2:
- Reorder DT changes before dt-bindings changes;
- Update adc-chan generic node name in tm5 example bindings.

v2: https://lore.kernel.org/linux-arm-msm/20230119212632.185881-1-marijn.suijten@somainline.org/T/#u

Changes since v1:
- Require adc-chan name in dt-bindings;
- Replace more node names with adc-chan and a descriptive label, that
  were found by running dtbs_check on adjusted bindings;
- sm8250-mtp.dts: Fix accidental adc-chan2 node name with pa_therm
  label, which should have been adc-chan with pa_therm2 label.

v1: https://lore.kernel.org/linux-arm-msm/20221209215308.1781047-1-marijn.suijten@somainline.org/
