Subject: [PATCH v10 10/13] ARM: dts: exynos: add chipid label and syscon compatible
Date: Fri, 14 Jun 2019 11:53:06 +0200
Message-ID: <20190614095309.24100-11-l.luba@partner.samsung.com> (raw)
In-Reply-To: <CGME20190614095329eucas1p267244e53d4f5612c46d6cc2c6bc0ed75@eucas1p2.samsung.com>

Add the chipid label which allows to use it in phandle from other device.
Use syscon in compatible to get the regmap of the device register set.
The chipid is used in DMC during initialization to compare compatibility.
