Mon Jul 26 00:14:38 PDT 2021
Add basic chip support for Mediatek mt7986a, include
uart nodes with correct clocks, rng node with correct clock,
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,
infracfg_ao (always on), apmixedsys and ethernet subsystem.
