Subject: [PATCH] arm64: dts: renesas: enable SDR104 on R-Car Gen3
Date: Tue, 21 Aug 2018 21:03:56 +0200	[thread overview]
Message-ID: <20180821190356.32070-1-wsa+renesas@sang-engineering.com> (raw)

Successfully tested on H3 ES1.0 and ES2.0, M3-W ES1.0, and M3-N ES1.0.
Even previously stubborn cards work fine. Transfer rates were >60MB/s.

Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

The problems I reported last week were simply me booting the wrong kernel on H3
ES1.0 :(
