Qualcomm Technologies, Inc. GFX LDO for Graphics

The GPU core on MSM TITANIUM can be powered by an internal (on-die)

The GPU core on MSM 8953 can be powered by an internal (on-die)

MSM LDO or BHS based on its operating corner.

This document describes the bindings that apply for the GFX LDO regulator.

- compatible

	Usage:      required

	Value type: <string>

	Definition: should be "qcom,msmtitanium-gfx-ldo" for MSMTITANIUM.

	Definition: should be "qcom,msm8953-gfx-ldo" for MSM8953.

- reg

	Usage:      required

		    corner value for each gfx corner. The elements in the array

		    are ordered from lowest voltage corner to highest voltage corner.

- qcom,ldo-init-voltage-adjustment

	Usage:      optional

	Value type: <prop-encoded-aray>

	Definition: Array of voltages in microvolts which indicate the static

		    adjustment to be applied to the open-loop voltages for the

		    LDO supported corners. The length of this property must be

		    equal to qcom,num-ldo-corners.
