Subject: [PATCH v4] regulator: dt-bindings: microchip,mcp16502: convert to YAML
Convert devicetree binding mcp16502-regulator.txt to YAML format.
Signed-off-by: Andrei Simion <andrei.simion@...rochip.com>
Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

Changes v3 -> v4:
- "additionalProperties: false" placed just after the required list
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
-
-Each regulator is defined using the standard binding for regulators.
