pwm is work.

shawnhsoia97 commented 3 years ago

Hi @xlla, I also want to set PWM mode, but I have not found /sys/kernel/debug/pinctrl_pinmux/pinmux in my kernel (branch zeus). I tried used below code in my .asl files and use /sys/class/pwm class test , but which is not effect.

External (_SB_.PCI0.PWM0, DeviceObj)

Scope (\_SB.PCI0.PWM0)
{
    Name (RBUF, ResourceTemplate ()
    {
        PinFunction(Exclusive, PullUp, 0x0001,
            "\\_SB.FLIS", 0, ResourceConsumer, , ) { 12 }
    })
    Method (_CRS, 0, NotSerialized)
    {
        Return (RBUF)
    }
}

Please, Could you tell me how to use PWM? I need to switch GP12 to PWM mode1. Thank you.

@shawnhsoia97, @xlla had been active almost couple of years ago and here is their branch with the experimental patches: https://github.com/xlla/linux/commits/eds-acpi-5.5.0-v1. We are free to accept the cleaned up version of the pinmux support (note there is some development regarding this feature in upstream as well in a similar way). So, feel free to take these and update, we will review and merge in the kernel in meta-intel-edison.
