Ben Zhang efd901ee4b ASoC: rt5677: Switch to use descriptor-based gpiod API
This patch makes the driver use the new descriptor-based gpiod API
so that gpio assignment info can be provided by Device Tree, ACPI
or board files.

Oder Chiou ab1f70952f ASoC: rt5677: Add the chip type to distinguish the setting of the clock source
There is only one clock source in the rt5676, so the chip type is added to
distinguish the setting of the clock source in the VAD function.

Dylan Reid 40e3262e42 ASoC: rt5677: make volume TLV closer to reality
The volume blocks have an step of 0.375dB, but TLV uses 0.01dB for
units.  Only use the resolution supported, ignoring the LSB of the
volume register.  This results in half the steps and 0.75dB per step,
but reports accurate levels through TLV.  Update the masks to reflect
that these are registers have the LSB ignored.

Oder Chiou 6fe17da00b ASoC: rt5677: Fix the issue that the regmap_range "rt5677_ranges" cannot be accessed
After the patch "ASoC: rt5677: Use specific r/w function for DSP mode", the
regmap_range "rt5677_ranges" was not registered in rt5677_regmap_physical, and
it caused that the regmap_range "rt5677_ranges" cannot be accessed by the
specific r/w function. The patch fixes this issue.

Oder Chiou e6f6ebc1f8 ASoC: rt5677: Add TDM channel mapping function
It is for channel to slot mapping, and it is not only for 8 channels mapping,
but also in 2, 4 and 6 channels mapping. If we want to use the 2 channels in
the stereo2 adc path, we need to set the item "2/1/3/4" or "2/3/1/4".

It also adds for stereo channel swap. It can map the sterero channels "L/R"
to "R/L", "L/L" or R/R.

Oder Chiou af48f1d08a ASoC: rt5677: Support DSP function for VAD application
The ALC5677 has a programmable DSP, and there is a SPI that is dadicated for DSP
firmware loading. Therefore, the patch includes a SPI driver for writing the DSP
firmware. The VAD(Voice Activaty Detection) has be implemented and use the DSP to
recognize the key phase.

Axel Lin 099d334e3d ASoC: rt5677: Convert to use rl6231_pll_calc
The implementation of rt5677_pll_calc() has the same logic of rl6231_pll_calc().
The only difference is the lower boundary checking for freq_in.

This patch calls rl6231_pll_calc() instead of open-coded.
The k_bp of struct rt5677_pll_code is always false, thus also remove the
code to check pll_code.k_bp.
