Subject: [PATCH v2 2/2] dt-bindings: mmc: sdhci-am654: Add ti,suppress-v1p8-ena
Date: Thu, 17 Apr 2025 13:26:52 -0500 [thread overview]
Message-ID: <20250417182652.3521104-3-jm@ti.com> (raw)
In-Reply-To: <20250417182652.3521104-1-jm@ti.com>
This patch documents ti,suppress-v1p8-ena which is a flag
used to suppress V1P8_SIGNAL_ENA in sdhci_am654 driver. This
quirk is necessary to fix fail init issues across various
types of SD cards tested on Sitara K3 SoCs.
