Subject: [PATCH] arm64: dts: r8a7795: salvator-x: Add current sense amplifiers
Date: Tue, 28 Mar 2017 11:44:42 +0200 [thread overview]
Message-ID: <1490694282-9439-1-git-send-email-geert+renesas@glider.be> (raw)
Add device nodes for two Maxim max961x current sense amplifiers
sensing the VDD_0.8V and DVFS_0.8V lines.
Based on a patch for r8a7796-salvator-x.dts by Jacopo Mondi.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
