Subject: [PATCH 1/2] arm64: dts: ti: j721e-main: Add SDHCI nodes
Date: Thu, 19 Sep 2019 21:02:41 +0530 [thread overview]
Message-ID: <20190919153242.29399-2-faiz_abbas@ti.com> (raw)
In-Reply-To: <20190919153242.29399-1-faiz_abbas@ti.com>
Add nodes for the 3 SDHCI instances present on TI's J721E device.
instance 0 supports HS400 (8 bit bus widht, DDR, 400 MBps)
while instances 1 and 2 support SDR104 (4 bit width, SDR, 100 MBps) as
their highest speed modes. Currently, only High speed (50 MHz clock) has
been enabled.
