From 64f6d07ba74c17305e2f953e41af260e5a63203b Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 6 May 2017 18:57:49 +0200 Subject: [PATCH] pinctrl: meson: meson8: add support for the I2S and SPDIF pins This adds support for the I2S and SPDIF input and output pins, similar to what we have on GXBB and GXL.
