Subject: [PATCH v4 1/9] dt-bindings: mfd: brcm,bcm59056: Convert to YAML
Convert devicetree bindings for the Broadcom BCM59056 PMU MFD from
TXT to YAML format. This patch does not change any functionality;
the bindings remain the same.
The bindings have been split into two parts: the MFD binding and
a separate binding for the regulator node, to simplify the addition
of other models later (which have different regulators).
Signed-off-by: Artur Weber <aweber.kernel@...il.com>
---
Changes in v4:
- Made $ref use full schema path
- Cleaned up example
- Dropped regulator name list comment
- Changed description of regulator binding to mention BCM59056
explicitly
- Changed "Power Management IC" to "Power Management Unit" to match
official Broadcom naming
- Renamed mfd/brcm,bcm59056.yaml to mfd/brcm,bcm590xx.yaml
Changes in v3:
- Moved regulator node to separate binding
- Removed quotes around compatibles/vbus property
- Style fixes for example

-Required properties:
-- compatible: "brcm,bcm59056"
-- reg: I2C slave address
-- interrupts: interrupt for the PMU. Generic interrupt client node bindings
- are described in interrupt-controller/interrupts.txt
-
-------------------
-Voltage Regulators
-------------------

-Optional child nodes:
-- regulators: container node for regulators following the generic
- regulator binding in regulator/regulator.txt

- The valid regulator node names for BCM59056 are:
- rfldo, camldo1, camldo2, simldo1, simldo2, sdldo, sdxldo,
- mmcldo1, mmcldo2, audldo, micldo, usbldo, vibldo,
- csr, iosr1, iosr2, msr, sdsr1, sdsr2, vsr,
- gpldo1, gpldo2, gpldo3, gpldo4, gpldo5, gpldo6,
- vbus

-Example:
- pmu: bcm59056@8 {
- compatible = "brcm,bcm59056";
- reg = <0x08>;
- interrupts = <GIC_SPI 215 IRQ_TYPE_LEVEL_HIGH>;
- regulators {

- regulator-max-microvolt = <3300000>;
