+Subject: [05/13] arm64: dts: rockchip: Add analog audio on ODROID-M1
+Origin: https://git.kernel.org/linus/78f858447cb78cac7259093d095fb783328b835c
+
+On the ODROID-M1, the I2S1 TDM controller is connected to the rk809
+codec in I2S mode. It is used to provide a stereo headphones output and
+a mono speaker output. A GPIO with an external pullup is used as an
+headphone detection input.
