Subject: [PATCH v3 5/5] MIPS: Loongson64: Add ISA node for LS7A PCH
Date: Sat, 25 Jul 2020 09:45:19 +0800
Message-ID: <20200725014529.1143208-6-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20200725014529.1143208-1-jiaxun.yang@flygoat.com>

Although currently we're not enabling any ISA device in devicetree,
but this node is required to express the ranges of address reserved
for ISA.
