From a39a3b9f4ff0aba7c2c475afaa52a3eb52d2b9ad Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Thu, 15 Jun 2017 23:33:47 +0200 Subject: [PATCH] ARM: dts: meson: add the SAR ADC This adds the SAR ADC to meson.dtsi and configures the clocks on Meson8 and Meson8b to allow boards to use it. Some boards use it to connect a button to it.
