Subject: [RFC PATCH] dt-bindings: regulator: twl-regulator: convert to yaml
Date: Tue, 28 May 2024 08:57:56 +0200
Message-Id: <20240528065756.1962482-1-andreas@kemnade.info>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Convert the regulator bindings to yaml files. To allow only the regulator
compatible corresponding to the toplevel mfd compatible, split the file
into one per device.

To not need to allow any subnode name, specify clearly node names
for all the regulators.

Drop one twl5030 compatible due to no documentation on mfd side and no
users of the twl5030.

Signed-off-by: Andreas Kemnade <andreas@kemnade.info>
---
Reason for being RFC:
the integration into ti,twl.yaml seems not to work as expected
make dt_binding_check crashes without any clear error message
if used on the ti,twl.yaml

-For twl4030 regulators/LDOs:
- - regulator-initial-mode:
-  - 0x08 - Sleep mode, the nominal output voltage is maintained with low power
-           consumption with low load current capability.
-  - 0x0e - Active mode, the regulator can deliver its nominal output voltage
-           with full-load current capability.
