From 5d5529b0057146043a4328aa194280299ba966c2 Mon Sep 17 00:00:00 2001 From: John Watts Date: Mon, 18 Sep 2023 23:15:32 +1000 Subject: [PATCH] ASoC: dt-bindings: wlf,wm8782: Add wlf,fsampen property 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.
