[PATCH 2/2] ASoC: rockchip: cdn-dp sound output use spdif

From: Lin Huang
Date: Tue May 22 2018 - 03:59:44 EST


some monitors care about the parity bit in the sub-frame of I2S,
but the cdn-dp always set this bit to "1", so these monitors
do not have sound output if use i2s, use spdif can fix this issue.
