for higher drive levels on the amplifier outputs.

PowerTune controls the power level of the chip.  On playback this
indirectly controls things like the gain of the various output
amplifiers.  This can allow for the decrease of output levels
from the codec.  This adds controls for those power levels to
the driver.

Should this be runtime controllable or is this something that's likely
to be fixed by the board design?

For us, in our particular application, it’s really necessary at runtime. Our use
case is not that we are driving speakers, but the inputs of various amateur 
radio units. Experience has shown us that the input characteristics of these 
devices vary widely and require different levels of drive to function 
correctly; a Motorola may need a lot of drive compared to an Icom that 
requires almost none. 

We could modify the board to have an outboard amplifier of some sort on 
it, but that just moves the problem to another component.   Or we could put 
some sort of prescaling switchable resistors in the board, but this also adds 
complexity that’s dubious. 

I’ve thought about putting these in the DT, but it occurs to me that they are 
really not board design dependent. The options are really there to control 
power consumption on the chip. In our application that’s really not important. 
For other applications I can see where that might be useful to change 
dynamically at runtime depending on current conditions.

The patch

   ASoC: tlv320aic32x4: Add Playback PowerTune Controls

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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
