[PATCH 1/6] ASoC: tlv320adcx140: Idle the device while writing registers

[PATCH 1/6] ASoC: tlv320adcx140: Idle the device while writing registers

[Dan Murphy]

It was observed that if the device was active and register writes were
performed there were some unwanted behaviors particularly when writing
the word length and some filter options. So when writing to the device
the device should be placed in sleep mode and then exit sleep mode once
the register update is complete.

[PATCH 2/6] ASoC: tlv320adcx140: Fix BCLK inversion for DSP modes

[Dan Murphy]

Fix the BCLK inversion for DSP modes
This is how it is defined by ASoC:
 * BCLK:
 * - "normal" polarity means signal is available at rising edge of BCLK
 * - "inverted" polarity means signal is available at falling edge of BCLK

The adcx140 defines the BCLK edge based on coding type.
The PCM (DSP_A/B) should drive on rising and sample on falling edge, so
from ASoC pov, it is IB_NF. But from the codec pov if it is configured in
DSP mode, then the BCLK should not be inverted, defaults to the coding
standard.

For i2s, it is NB_NF from ASoC pov (drive on falling, sample on rising).
From the codec's pov BCLK should not invert either, as this is the default
for the coding.

So, inversion must take the format into account:
IB_NF + DSP_A/B == the codec bclk inversion should be disabled
NB_NF + DSP_A/B == the codec bclk inversion should be enabled
NB_NF + I2S == the codec bclk inversion should be disabled

Add code to allow the ASI Tx output to be placed into High-z mode

This is something I'd expect to be done by the machine driver rather
than in the CODEC specific DT bindings, and apart from anything else
everything involved in the DAI will need to agree on the mapping so this
doesn't look like something that should be done in a device specific
binding.

Here is the use case from our customers

Customers need the ability to not transmit on a TDM slot, since another 
device could be using the slot.
For example, the customer has an amp and dig microphone sharing one TDM 
bus. The amp uses slot 0 while dig microphone use slots 1-3.
In another example, customers use 2 dig microphones. One device 
transmits on slots 0-3, the second device transmits on slots 4-7.
In a third example, customers use 4 dig microphones. Device 1 uses Slots 
0-3, Device 2 uses Slots 4-7, Device 3 uses Slots 8-11, and Device 4 
uses Slots 12-15.

The dai-tdm-slot-num would be a good candidate to add to the sound card 
to define the slot number but it's definition is "Number of slots in 
use." So it is not really setting the needed slot.
I am not finding any good way to assign specific slots to specific channels.

I can add DAI slot numbering parameter for specific codecs.

TDM is not an issue, we already have the set_tdm_slot() API.  The issue
is how you're configuring it.

If the generic features are not sufficent then please extend the generic
features rather than bodging around them in individual drivers.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
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
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
