From b66ce77e31a1b66618293c0706865ae4d23f4f9a Mon Sep 17 00:00:00 2001 From: Sugar Zhang Date: Fri, 30 Jun 2023 18:30:32 +0800 Subject: [PATCH] arm64: dts: rockchip: rk1808: Enable Schmitt-Trigger for pins I2Sx-CLK This patch enable Schmitt-Trigger for pins I2S-MCLK/BCLK/LRCK for clk noise reduction on slave mode which clk is provided by external devices. and this can make controllers work much more robust.
