Re: [PATCH 4/4] ASoC: ac97: Convert to GPIO descriptors

of_gpio.h is deprecated, update the driver to use GPIO descriptors.

Since the driver still pass the reset_gpio to pxa27x_configure_ac97reset,
so use desc_to_gpio() to get it gpio id.

GPIO

Why can't we convert that one to use GPIO descriptor to begin with?

...

 	if (dev->dev.of_node) {
-		reset_gpio = of_get_named_gpio(dev->dev.of_node, "reset-gpios", 0);
-		if (reset_gpio == -ENOENT)
+		/* Assert reset using GPIOD_OUT_HIGH, because reset is GPIO_ACTIVE_LOW */
+		rst_gpio = devm_gpiod_get(&dev->dev, "reset", GPIOD_OUT_HIGH);
+		ret = PTR_ERR(rst_gpio);
+		if (ret == -ENOENT)
 			reset_gpio = -1;
-		else if (reset_gpio < 0)
-			return reset_gpio;
+		else if (ret)
+			return ret;
+		reset_gpio = desc_to_gpio(rst_gpio);

Also, have you considered moving towards 'reset-gpio' driver?

...

And last but not least Q, have you checked gpiolib-of.c if there is any quirks
regarding this case (might be some fixes related to polarity)?
