Fix the problem of "ROC-RK3588S-PC" fan full-speed run

[travel-star]

1.add firefly source list into /etc/apt/sources.list.d
deb http://wiki.t-firefly.com/firefly-ubuntu-repo jammy main
deb http://wiki.t-firefly.com/firefly-rk3588-repo focal main
cp trusted.gpg into /etc/apt
trusted.zip

2.install firefly's firefly-fan
apt-get update
apt-get upgrade
apt-get install firefly-fan

3.change /usr/bin/firefly-fan-init(the init program can‘t correct identification the board model)
line 5
change"RK3588_BOARD_VERSION=cat /sys/firmware/devicetree/base/model | awk -F ' ' {'print $2'}"to"RK3588_BOARD_VERSION=cat /sys/firmware/devicetree/base/model | awk -F ' ' {'print $1'}"

restart firefly-fan
systemctl restart firefly-fan.service

Wooo! this word is so silent.

I wonder why there are not any default cooling levels in the device tree to prevent the fan from going full-blast. I would add something like the below code to the DTS. But I don't have the board to test this out.
