Just a nitpick but this should be alphabetical too.

You can drop the status since the default is "okay".

Can you add a blank line? It's just a nitpick.

I don't know the policy but I would name the nodes and phandles always
in lower case.

What is 'en-supply'? Just checked the v5.1-rc5 and didn't found that
property at all. This applies to the other regulator nodes too.

You missed the pinctrl-0, pinctrl-names property since you already have
a pinctrl_pwr_en phandle.

IMHO you should mux (pinctrl) a gpio where you use them but that's only
my opinion.

A fixed regulator without a regulator-min-microvolt
regulator-max-microvolt?

Where do you mux that gpio? It seems that you use the
pinctrl_usdhc2_gpio for muxing but there is no GPIO3 mux.

status should be the last property in this list.

Is it necessary to name it ethphy0? Just a nitpick.

Please swap the reg and compatible property.

Please drop the #address-cells, #size-cells and the @<reg> suffix
including the reg = <> property. So it would look like:

			buck1_reg: BUCK1 {
				regulator-name = "buck1";
				regulator-min-microvolt = <700000>;
				regulator-max-microvolt = <1300000>;
				regulator-boot-on;
				regulator-always-on;
				regulator-ramp-delay = <1250>;
				rohm,dvs-run-voltage = <900000>;
				rohm,dvs-idle-voltage = <850000>;
				rohm,dvs-suspend-voltage = <800000>;
			};

Please look at
Documentation/devicetree/bindings/regulator/rohm,bd71837-regulator.txt.

The reg = <> should be followed after the compatible.

The vconn-supply isn't documented elsewhere.

Just a nitpick but I would break the lines, e.g.

			source-pdos = <PDO_FIXED(5000, 2000, PDO_FIXED_USB_COMM |
							     PDO_FIXED_DUAL_ROLE |
							     PDO_FIXED_DATA_SWAP )>;

IMHO I would comment only the measurments.

Why do you don't mux the pinctrl_imu within the magnetometer@1e node?

The reg = <> should be followed the compatible string.

Didn't found any of these supplies. Can you drop them?

It seems a bit inconsistent to add a comment behind the

Just a nitpick but I would name it pinctrl_pwm2 as you did it for pwm1.

Why did you assign the #address-cells and #size-cells without specify
any port? Status should be the last property.

You can drop the pinctrl_usdhc2_gpio handle if you mux them within the
regulator node.
