From b8159df9fd871ac67219f2f254043c72c238bc6c Mon Sep 17 00:00:00 2001 From: Seven Lee Date: Mon, 29 Mar 2021 20:00:41 +0800 Subject: drivers/i2c/nau8825: Support nau8825 for ACPI GPIO descriptors Add definitions to describe GPIOs in generated ACPI objects. The method allow either write a GpioInt() or Interrupt() descriptor.
