Subject: [PATCH v5 08/12] ARM: mstar: Add Armv7 base dtsi
Date: Fri, 10 Jul 2020 18:45:40 +0900	[thread overview]
Message-ID: <20200710094544.430258-9-daniel@0x0f.com> (raw)
In-Reply-To: <20200710094544.430258-1-daniel@0x0f.com>

Adds initial dtsi for the base MStar/Sigmastar Armv7 SoCs.

These SoCs have very similar memory maps and this will avoid
duplicating nodes across multiple dtsis.
