Subject: [PATCH v5 3/3] ASoC: rt5677: fall back to DT prop names on error
Date: Tue,  7 May 2019 16:01:15 -0600	[thread overview]
Message-ID: <20190507220115.90395-4-fletcherw@chromium.org> (raw)
In-Reply-To: <20190507220115.90395-1-fletcherw@chromium.org>

The rt5677 driver uses ACPI-style property names to read from the
device API. However, these do not match the property names in _DSD
used on the Chromebook Pixel 2015, which are closer to the Device Tree
style.  Unify the two functions for reading from the device API so that
they try ACPI-style names first and fall back to the DT names on error.

With this patch, plugging and unplugging the headphone jack switches
between headphones and speakers automatically.
