For the BSP (3.10.x) kernel the PWM output (PL10 according to the schematics) is afaik tied to the LCD driver and there should be some controls in the /sys/ filesystem.
If you look at the device tree:
Pin Config:
https://github.com/longsleep/build-pine6...4.dts#L776
LCD Entry seems to have values too:
https://github.com/longsleep/build-pine6....dts#L1965
PWM Driver entry, from the pinctrl phandle:
https://github.com/longsleep/build-pine6....dts#L2071
from the compatible line it should be tied to a driver called "sunxi-pwm16"
