From d0e0bbe7d1c4bf1b64a12ed6b8a0304c50c99687 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 31 Oct 2018 20:34:41 +0100 Subject: [PATCH] ARM: dts: rmobile: Enable SDR modes on E3 Ebisu Add regulators and pinmuxes for SDHI0 and SDHI1 SD and microSD slots on E3 Ebisu and mark them as capable of up to SDR104 mode of operation. With the SDHI fixes in place, it is now possible to use SDR104.
