Subject: [PATCH v4 3/3] arm64: dts: qcom: Add refgen supplies for PCIe PHY on Glymur and Mahua boards
Date: Wed, 04 Nov 2026 01:08:02 -0800 [thread overview]
Message-ID: <20261104-phyrefgen_1104-v4-3-ba508fc6ab40@oss.qualcomm.com> (raw)
In-Reply-To: <20261104-phyrefgen_1104-v4-0-ba508fc6ab40@oss.qualcomm.com>
The PCIe PHYs on Glymur and Mahua require a reference voltage provided by
REFGEN, which in turn is powered by two LDOs.
Since there is no devicetree node for REFGEN, add the vdda-refgen0p9 and
vdda-refgen1p2 supplies for each PCIe PHY node.
