ENGR00306442-2 ARM: imx6sx: Fix audio noise during monaural audio playback
We should disable the pull up/down bit to the tx data pin as the pulling operation would cause I2S signal distortion. Thus this patches dropped the pull up/down bit of TXC pad and the useless 0x40000 bit from all of pads in the group. Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com>
