Newsgroups	org.infradead.lists.linux-phy,org.kernel.vger.linux-arm-msm,org.kernel.vger.linux-devicetree,org.kernel.vger.linux-kernel
Message-ID	<20260804-b4-sgmiieth_serdes_regulator-v2-5-c4bc688177dd@oss.qualcomm.com>

The SerDes PHY node was configured with 'phy-supply = <&vreg_l4a>',
which only described one of the two supplies the hardware requires.
While vreg_l4a is the correct 0.9V rail, the 1.2V rail (vreg_l5a)
was missing entirely.

Replace phy-supply with the two named properties vdda-0p9-supply
(vreg_l4a) and vdda-1p2-supply (vreg_l5a).
