From ec513886411e4fc47f98607a1bc79b72899710c4 Mon Sep 17 00:00:00 2001 From: Jeremy McDermond Date: Mon, 18 Apr 2016 17:24:04 -0700 Subject: [PATCH 1/7] ASoC: tlv320aic32x4: Change name of probe function The codec's probe function is named aic32x4_probe. This is going to conflict with later work to implement SPI support and separate out I2S into its own file. In line with other drivers in the tree, this function is renamed to aic32x4_codec_probe instead.

This patch creates an enum for each pin and allows you to switch between not connected, 10k, 20k and 40k ohm values. This more closely models the acutal aic3204 part. These pin settings are documented in TI's SLAA557 pages 135 and 136 (http://www.ti.com/lit/ml/slaa557/slaa557.pdf).

Each mixer has an available set of available pins that can be connected to the ADC positive and negative pins via three different resistor values. This allows for configuration of differential inputs as well as doing level manipulation between sources going into the mixers. The current code only provides positive pins and I implemented the resistors in an earlier patch. It turns out that it appears to more accurately model what's happening to implement each of the pins as a MUX rather than on/off switches and a mixer. This way each pin can be set to its desired resistor value. Since there are no switches, the mixer is no longer necessary in the DAPM path. I set the DAPM paths such that the "off" position of any of the MUXes turns the path off. This should allow for any input confiuration available on the codec.
