Subject: [PATCH v3] regulator: dt-bindings: microchip,mcp16502: convert to YAML

Convert devicetree binding mcp16502-regulator.txt to YAML format.

Signed-off-by: Andrei Simion <[email protected]>
---
Changes v2 -> v3:
- keep one line of regulators description
- add additionalProperties: false for regulators
- "description:" at the end for each properties

Changes v1 -> v2:
- reverse subject prefixes
- line break after file "description:"
- drop description for reg
- drop regulator-name
- add regulator-initial-mode
- unevaluatedProperties just after $ref: regulator.yaml#
- additionalProperties just before "required"
- node names generic in example
- drop reg property from i2c
- use 4 spaces for example indentation

-MCP16502 PMIC
-
-Required properties:
-- compatible: "microchip,mcp16502"
-- reg: I2C slave address
-- lpm-gpios: GPIO for LPM pin. Note that this GPIO *must* remain high during
- suspend-to-ram, keeping the PMIC into HIBERNATE mode; this
- property is optional;
-- regulators: A node that houses a sub-node for each regulator within
- the device. Each sub-node is identified using the node's
- name. The content of each sub-node is defined by the
- standard binding for regulators; see regulator.txt.
-
-Regulators of MCP16502 PMIC:
-1) VDD_IO - Buck (1.2 - 3.7 V)
-2) VDD_DDR - Buck (0.6 - 1.85 V)
-3) VDD_CORE - Buck (0.6 - 1.85 V)
-4) VDD_OTHER - BUCK (0.6 - 1.85 V)
-5) LDO1 - LDO (1.2 - 3.7 V)
-6) LDO2 - LDO (1.2 - 3.7 V)
-
-Regulator modes:
-2 - FPWM: higher precision, higher consumption
-4 - AutoPFM: lower precision, lower consumption
-

I missed it before, why did you move it? Previous placement was what we
expect. I did not comment about it.

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

Ah, I will place the "additionalProperties: false" as in my first attempt in v4. Thank you for clarification.
