6617cff6a0 ASoC: tlv320adcx140: Add GPO configuration and drive output config
Add General Purpose Output (GPO) configuration and driver output
configuration.  The GPOs can be configured as a GPO, IRQ, SDOUT or a
PDMCLK output.  In addition the output drive can be configured with
various configurations.

5856d8bd30 ASoC: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

3c35e79cea ASoC: tlv320adcx140: Add support for configuring GPI pins
Add support to configure the GPI pins to the specific configuration.
The pins can be disabled or be configured as data input for any of the
digital mic channels.  In addition the GPI can be used a a general
purpose input, a Master clock input or an ASI input for daisy chaining
devices.

0e36f32f6b ASoC: tlv320adcx140: Fix bias config values
The device tree binding declares the ti,mic-bias-source and the
ti,vref-source properties as u32.  The code reads them as u8 which is
incorrect.  Since the device tree binding indicates them as u32 the
conde needs to be updated to read u32.

In addition the bias source needs to be shifted 4 bits to
correctly write the register.

8a329dbd4a ASoC: tlv320adcx140: Add DRE and AGC support
The TLV320ADCx140 parts support Dynamic Range Enhancer (DRE) as defined
in Section 8.3.2 of the data sheets.

The DRE achieves a complete-channel dynamic range as high as 120 dB.
At a system level, the DRE scheme enables far-field, high-fidelity recording
of audio signals in very quiet environments and low-distortion recording in
loud environments.

There are 2 enables for DRE.  The first is a global setting that enables
the DRE engine in the device and the other enable is per channel.  If
the DRE is enabled globally then either DRE or AGC can be used per each
configured channel.  If global DRE is disabled then even setting the DRE
enable bit in the channel config register will have no effect.

689c7655b5 ASoC: tlv320adcx140: Add the tlv320adcx140 codec driver family
Add the tlv320adcx140 codec driver family.

The TLV320ADCx140 is a Burr-Brown™ highperformance, audio analog-to-digital
converter (ADC) that supports simultaneous sampling of up to four analog
channels or eight digital channels for the pulse density modulation (PDM)
microphone input. The device supports line and microphone inputs, and
allows for both single-ended and differential input configurations.
