I’d like to use the IR remote functionality of the S905Y2. The S905Y2 quick reference says that there’s both
IR_REMOTE_OUT signals that are mapped to gpio pins, and the datasheet (section 12.5) has a lot of information about receiving IR signals, though none about transmitting. But maybe the PWM functionality could be used for that?
I see the linux kernel has drivers for these things too. I can modprobe
pwm-meson successfully, but no device files appear. Trying to modprobe
meson-ir-tx gives an error, though (“No such device”).
Do I need a devicetree overlay to use these? Is it even possible on the Zero? Any tips would be appreciated.
(I know there are no IR sensors or leds on the board, I just want to hook them up to gpio pins)
