Subject: [PATCH v4 5/5] MIPS: Loongson64: Add ISA node for LS7A PCH
Date: Tue, 28 Jul 2020 23:36:59 +0800 [thread overview]
Message-ID: <20200728153708.1296374-6-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20200728153708.1296374-1-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.
