Hi,
This is the first time I send mail to linux-pwm, I didn't read through
the mails in this list, so if somebody already asked this question, I'm
sorry about that.
I wanna set some fops in "struct platform_pwm_backlight_data". But the
currrent probe function in pwm_bl.c says:
-------
if (!data) {
ret = pwm_backlight_parse_dt(&pdev->dev, &defdata);
if (ret < 0) {
dev_err(&pdev->dev, "failed to find platform data\n");
return ret;
}
data = &defdata;
}
-------
This looks like if we set the platform data for pwm backlight device,
"pwm_backlight_parse_dt" will never have a chance to be called, which
means the stuffs I defined in backlight DT node will be ignored.
If I don't set the platform data for pwm backlight device, according to
the pwm_backlight_probe, I will never have a chance to set some fops
which I need(like "notify", "check_fb"...).
So, what I suppose to do now? Maybe there is a way to set function
pointers in DT?
