At the moment, MIC BIAS Internal* and MIC BIAS External* both reference
the same register, and have a part of their initialization sequence
duplicated.
For example, the sequence for enabling MIC BIAS Internal1 is:
I1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN)
I2. Enable internal RBIAS (TX1_INT_RBIAS_EN bit in CDC_A_MICB_1_INT_RBIAS)
The sequence for enabling MIC BIAS External1 is:
E1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN)
(E2. Ideally, make sure internal RBIAS is disabled. However, this should
not happen in practice because DAPM will disable unused supplies...)
Right now we have:
SND_SOC_DAPM_SUPPLY("MIC BIAS Internal1", CDC_A_MICB_1_EN, 7, 0, ...) // I1
SND_SOC_DAPM_SUPPLY("MIC BIAS External1", CDC_A_MICB_1_EN, 7, 0, ...) // E1
and I2 is done in the PM event handler (pm8916_wcd_analog_enable_micbias_int1).
We can simplify this by defining a common DAPM supply for I1/E1 ("MIC_BIAS1"),
and one DAPM supply for I2 ("MIC BIAS Internal1"). Additional DAPM routes
ensure that we also enable the MIC_BIAS1 supply for the internal and external
pull up resistor.
Another advantage of this is that we now disable the internal RBIAS
when it is not needed. This makes it much easier to add support for
MIC BIAS Internal3 as a next step.

Changes in v2:
- Use an extra DAPM supply for MIC_BIASX that is referenced by
MIC BIAS InternalX and MIC BIAS ExternalX, instead of combining it with
MIC BIAS ExternalX
- Clarify commit message

PM8916 has three TX inputs that each have an (optional) internal
RBIAS resistor. MIC BIAS Internal1/2 (for TX1/2) are already supported.
TX3 does not have its own MIC BIAS supply, instead it is also supplied
from MIC_BIAS1.
Now that we have simplified the MIC BIAS Internal* implementation
we can easily add support for it:
Add a MIC BIAS Internal3 supply that enables the internal RBIAS
resistor on TX3, and make sure to also enable the MIC_BIAS1 supply.

the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing

Subject: [PATCH] ASoC: msm8916-wcd-analog: Add MIC BIAS Internal3
PM8916 has three TX inputs that each have an (optional) internal
RBIAS resistor. MIC BIAS Internal1/2 (for TX1/2) are already supported.
TX3 does not have its own MIC BIAS supply, instead it is also supplied
from MIC_BIAS1.
Now that we have simplified the MIC BIAS Internal* implementation
we can easily add support for it:
Add a MIC BIAS Internal3 supply that enables the internal RBIAS
resistor on TX3, and make sure to also enable the MIC_BIAS1 supply.

Subject: [PATCH] ASoC: msm8916-wcd-analog: Simplify MIC BIAS Internal
At the moment, MIC BIAS Internal* and MIC BIAS External* both reference
the same register, and have a part of their initialization sequence
duplicated.
For example, the sequence for enabling MIC BIAS Internal1 is:
I1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN)
I2. Enable internal RBIAS (TX1_INT_RBIAS_EN bit in CDC_A_MICB_1_INT_RBIAS)
The sequence for enabling MIC BIAS External1 is:
E1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN)
(E2. Ideally, make sure internal RBIAS is disabled. However, this should
not happen in practice because DAPM will disable unused supplies...)
Right now we have:
SND_SOC_DAPM_SUPPLY("MIC BIAS Internal1", CDC_A_MICB_1_EN, 7, 0, ...) // I1
SND_SOC_DAPM_SUPPLY("MIC BIAS External1", CDC_A_MICB_1_EN, 7, 0, ...) // E1
and I2 is done in the PM event handler (pm8916_wcd_analog_enable_micbias_int1).
We can simplify this by defining a common DAPM supply for I1/E1 ("MIC_BIAS1"),
and one DAPM supply for I2 ("MIC BIAS Internal1"). Additional DAPM routes
ensure that we also enable the MIC_BIAS1 supply for the internal and external
pull up resistor.
Another advantage of this is that we now disable the internal RBIAS
when it is not needed. This makes it much easier to add support for
MIC BIAS Internal3 as a next step.
