This patch enables getting a HPD GPIO descriptor quicker.
The exynos-hdmi driver uses "hpd" for HDMI hot plug detection.
static int hdmi_resources_init(struct hdmi_context *hdata)
{
...
hdata->hpd_gpio = devm_gpiod_get(dev, "hpd", GPIOD_IN);
...
}
This calls 'of_find_gpio()' and it generates the GPIO consumer ID by referring
GPIO suffix. So 'hpd-gpios' is preferred on getting a GPIO descriptor.
However, if the device tree uses 'hpd-gpio', then the exynos-hdmi driver
always retries to get a GPIO descriptor because the first GPIO suffix is not
'gpio' but 'gpios'. So you always see the debug message below.
of_get_named_gpiod_flags: can't parse 'hpd-gpios' property of node '/soc/hdmi@14530000[0]'
Use the preferred property, 'hpd-gpios' instead of 'hpd-gpio'.
