Subject: [PATCH 5/8] arm64: dts: ti: k3-j721e-common-proc-board: Add support SD card UHS modes
Date: Fri, 2 Oct 2020 00:35:38 +0530 [thread overview]
Message-ID: <20201001190541.6364-6-faiz_abbas@ti.com> (raw)
In-Reply-To: <20201001190541.6364-1-faiz_abbas@ti.com>
Add support for UHS modes for the SD card connected at sdhci1. This
involves adding regulators for voltage switching and power cycling the
SD card and removing the no-1-8-v property.
