Subject: [PATCH v2 3/3] ASoC: dt-bindings: wlf,wm8782: Add wlf,fsampen property
Date: Thu, 14 Sep 2023 03:15:52 +1000 [thread overview]
Message-ID: <20230913171552.92252-4-contact@jookia.org> (raw)
In-Reply-To: <20230913171552.92252-1-contact@jookia.org>
The WM8782 can safely support rates higher than 48kHz by changing the
value of the FSAMPEN pin.
Allow specifying the FSAMPEN pin value in the device tree.
