Subject: [PATCH v4 5/6] ARM: dts: Add "syscon" compatible string to chipid node
Date: Tue, 10 Sep 2019 14:36:17 +0200
Message-ID: <20190910123618.27985-6-s.nawrocki@samsung.com> (raw)
In-Reply-To: <20190910123618.27985-1-s.nawrocki@samsung.com>

The CHIP ID block in addition to exact chip revision information
contains data and control registers for ASV (Adaptive Supply Voltage)
and ABB (Adaptive Body Bias). Add "syscon" compatible so the CHIPID
block can be shared by respective drivers.
