IR receiver stops working after suspend/resume

[tanod]

Hey @amazingfate,

 

I have an issue with the build-in IR receiver on my OPI5+:

After a reboot it works just fine, but once I suspend/resume it stops working. Logs look clear of errors.

I have tried to troubleshoot with ChatGPT but goin' in circles and gave up. Lastly ended up with some speculations from it like:

The driver at drivers/input/remotectl/rockchip_pwm_remotectl.c is missing pm_ops callbacks, which are used to restore hardware state after resume.

It needs something like this added:

 

static int rockchip_pwm_remotectl_resume(struct device *dev)
{
    struct remotectl_dev *rc_dev = dev_get_drvdata(dev);

    // Re-init or restart the device
    if (rc_dev && rc_dev->restart)
        rc_dev->restart(rc_dev);

    return 0;
}

static const struct dev_pm_ops rockchip_pwm_remotectl_pm_ops = {
    .resume = rockchip_pwm_remotectl_resume,
};

And then linked to the platform driver:

 

static struct platform_driver rockchip_pwm_remotectl_driver = {
    .probe = rockchip_pwm_remotectl_probe,
    .driver = {
        .name = "rockchip_pwm_remotectl",
        .pm = &rockchip_pwm_remotectl_pm_ops,
    },
};

 

 

Do you think this is the problem, or if not can I share some details so you can try to find it?
