The Allwinner A64 SoC features two PWM controllers, which are fully compatible to the one used in the A13 and H3 chips. Add the respective device nodes (one for the "normal" PWM, the other for the one in the CPUS domain) and the pin their output is connected to.
"Add the nodes for the devices (...) and the pins their outputs are connected to."
On the A64 the "normal" PWM is muxed together with one of the MDIO pins used to communicate with the Ethernet PHY, so it won't be usable on many boards. But the Pinebook laptop uses this pin for controlling the LCD backlight. The CPUS PWM pin however is routed to the "RPi2" header, at the same location as the PWM pin on the RaspberryPi.
The last sentence is misssing a reference to the Pine64.
