Also, there's this section in the driver:

#ifdef CONFIG_ACPI
static const struct acpi_device_id pca9685_acpi_ids[] = {
{ "INT3492", 0 },
{ /* sentinel */ },
};
MODULE_DEVICE_TABLE(acpi, pca9685_acpi_ids);
#endif

Which means there might be arm64 or intel devices out there that define
presence of this chip via an ACPI tree. Which exists only inside bioses
and would not show up in any devicetree.
