From e6dc10f200dae6ca9965fafa3733aff44bde9e9f Mon Sep 17 00:00:00 2001 From: Faiz Abbas Date: Thu, 19 Sep 2019 21:02:41 +0530 Subject: [PATCH] arm64: dts: ti: j721e-main: Add SDHCI nodes 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.
