ASoC: tlv320aic32x4: Fix MICPGA input configuration
Currently the Negative Terminal Input Routing Configuration is only set when there is a special routing configuration. If we don't use one of the inputs IN1 or IN2 as negative terminal input, the PGA and recording does not work. This patch adds a route from CM1L/CM1R to the PGA as negative input by default. With this configuration the PGA can amplify all input signals and line-in/mic works again. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
