Subject: [PATCH V3 4/5] dt-bindings: regulator: Convert RPMh regulator bindings to YAML
Convert RPMh regulator bindings from .txt to .yaml format.
Signed-off-by: satya priya <skakit@...eaurora.org>
---
Changes in V2:
- As per Mark's comment moved this patch to the end of series.
- As per Rob's comments, added flash and rgb bindings, dropped allOf and
unused labels and fixed few other things.
Changes in V3:
- Fixed bot errors and also changed commit text to specify RPMh regulator
bindings.

-Qualcomm Technologies, Inc. RPMh Regulators
-
-rpmh-regulator devices support PMIC regulator management via the Voltage
-Regulator Manager (VRM) and Oscillator Buffer (XOB) RPMh accelerators. The APPS
-processor communicates with these hardware blocks via a Resource State
-Coordinator (RSC) using command packets. The VRM allows changing three
-parameters for a given regulator: enable state, output voltage, and operating
-mode. The XOB allows changing only a single parameter for a given regulator:
-its enable state. Despite its name, the XOB is capable of controlling the
-enable state of any PMIC peripheral. It is used for clock buffers, low-voltage
-switches, and LDO/SMPS regulators which have a fixed voltage and mode.
-
-=======================
-Required Node Structure
-=======================
-
-RPMh regulators must be described in two levels of device nodes. The first
-level describes the PMIC containing the regulators and must reside within an
-RPMh device node. The second level describes each regulator within the PMIC
-which is to be used on the board. Each of these regulators maps to a single
-RPMh resource.
-
-The names used for regulator nodes must match those supported by a given PMIC.
-Supported regulator node names:
- PM8005: smps1 - smps4
- PM8009: smps1 - smps2, ldo1 - ldo7
- PM8150: smps1 - smps10, ldo1 - ldo18
- PM8150L: smps1 - smps8, ldo1 - ldo11, bob, flash, rgb
- PM8350: smps1 - smps12, ldo1 - ldo10,
- PM8350C: smps1 - smps10, ldo1 - ldo13, bob
- PM8998: smps1 - smps13, ldo1 - ldo28, lvs1 - lvs2
- PMI8998: bob
- PM6150: smps1 - smps5, ldo1 - ldo19
- PM6150L: smps1 - smps8, ldo1 - ldo11, bob
- PMX55: smps1 - smps7, ldo1 - ldo16
