Subject: [PATCH] arm64: dts: rockchip: enable I2S codec on rk3399-puma-haikou
Enable the NXP SGTL5000 audio codec on the RK3399-Q7 EVK baseboard
Haikou.
The i2s0_2ch_bus definition is only done in the SoM dtsi as it is
missing the LRCK_RX pin (that is used otherwise) and therefore not
generic enough for the SoC dtsi.
