Date: Tue, 17 May 2022 14:00:00 +0200 From: Robert Marko <robimarko@...il.com> To: agross@...nel.org, bjorn.andersson@...aro.org, lgirdwood@...il.com, broonie@...nel.org, robh+dt@...nel.org, krzysztof.kozlowski+dt@...aro.org, linux-arm-msm@...r.kernel.org, linux-kernel@...r.kernel.org, devicetree@...r.kernel.org Cc: Robert Marko <robimarko@...il.com> Subject: [PATCH v2 6/6] arm64: dts: ipq8074: add VQMMC supply SDHCI controller claims DDR, HS200 and HS400 1.8V support, however it cannot achieve those using the 2.95V I/O that is the default set by firmware. Since we know have access to the PMP8074 PMIC provided LDO that provides the I/O voltage set it as VQMMC supply so that higher speeds can actually be achieved.
