[PATCH 1/2] arm64: dts: rockchip: r4s: system status LEDs changed to flashing light

[Xiaobo Tian]

There are 4 LEDs on the motherboard, except for the power lamp,
which are LED-0 STATUS, LED-1 LAN, LED-2 WAN.
The LED-0 is repeatedly defined and therefore removed
and inherited the heartbeat status LED-0 using dtsi.

[PATCH 2/2] arm64: dts: rockchip: r4s: remove the vcc3v3 use vcc5v0 wrong supply voltage

[Xiaobo Tian]

Vcc3v3 wrongly used Vcc5v0 for power supply.
After testing and removing this misconfiguration,
the temperature of the motherboard has decreased,
and it works normally without any other problems
