Changes since v3:
- Added missing routes for In-mixer left and right
- Added comment explaining rational behind use of STANDBY registers
Changes since v1:
- used supply widget for mic bias
- removed mic bias hookup
- assigned dapm widgets and routes in card struct
- removed explicit setting of default mixer settings
- removed explicit setting of ios to standby mode

+/*
+ * DAPM Controls
+ *
+ * Current DAPM implementation covers almost all codec components e.g. IOs,
+ * mixers, PGAs,ADC and DAC.
+ *
+ * For DA7210 codec, there are two ways to enable/disable analog IOs and
+ * ADC/DAC,
+ * (1) Using "Enable Bit" of register associated with that IO(or ADC/DAC)
+ * e.g. Mic Left can be enabled using bit 7 of MIC_L(0x7) reg
+ *
+ * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
+ * e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5) reg
+ *
+ * Out of these two methods, the one using STANDBY bits is preferred way to
+ * enable/disable individual blocks. This is because STANDBY registers are part
+ * of system controller which allows system power up/down in a controlled,
+ * pop-free manner. Also, as per application note of DA7210, STANDBY register
+ * bits are only effective if a particular IO (or ADC/DAC) is already enabled
+ * using enable/disable register bits. Keeping these things in mind, current
+ * DAPM implementation manipulates only STANDBY bits.
+ *
+ * Overall implementation can be outlined as below,
+ *
+ * - "Enable bit" of an IO or ADC/DAC is used to enable it in probe() function
+ * - "STANDBY bit" is controlled by DAPM
