Subject: [PATCH 6/6] arm64: dts: ipq8074: add VQMMC supply
Date: Sun, 15 May 2022 22:31:18 +0200 [thread overview]
Message-ID: <20220515203118.474684-6-robimarko@gmail.com> (raw)
In-Reply-To: <20220515203118.474684-1-robimarko@gmail.com>
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.
