Subject: [v2,11/12] arm64: dts: mediatek: add mt7986a support
Date: Tue, 17 Aug 2021 15:45:56 +0800	[thread overview]
Message-ID: <20210817074557.30953-12-sam.shih@mediatek.com> (raw)
In-Reply-To: <20210817074557.30953-1-sam.shih@mediatek.com>

Add basic chip support for Mediatek mt7986a, include
uart nodes with correct clocks, rng node with correct clock,
and watchdog node and mt7986a pinctrl node.

Add cpu node, timer node, gic node, psci and reserved-memory node
for ARM Trusted Firmware,

Add clock controller nodes, include 40M clock source, topckgen, infracfg,
apmixedsys and ethernet subsystem.

Signed-off-by: Sam Shih <sam.shih@mediatek.com>
