+Subject: [PATCH] arm64: dts: qcom: ipq8074-hk01: add VQMMC supply
+
+Since now we have control over the PMP8074 PMIC providing various system
+voltages including L11 which provides the SDIO/eMMC I/O voltage set it as
+the SDHCI VQMMC supply.
+
+This allows SDHCI controller to switch to 1.8V I/O mode and support high
+speed modes like HS200 and HS400.
