Add Realtek ALC5631/RT5631 codec support to the Tegra ASoC machine driver.
The RT5631 codec is found on devices like ASUS Transformer TF201, TF700T
and other Tegra-based Android tablets.

This comment doesn't make sense now.  It was never super useful, though.
Just delete it.

Your signoff should be last if you're the one sending this.

It feels like this is complicated enough and looks like the
clocking is flexible enough that it might be easier to just have
a table of values or otherwise enumerate standard rates, seeing
the code I feel like I need to worry about what happens if we
pick a clock rate over 6MHz (the loop could give a value over
that), and it's not clear why we have the switch statement rather
than just starting at a multiple of 128 and looping an extra time.

I suspect there's going to be no meaningful downside for having
the clock held at over 3MHz on a tablet form factor, the usual
issue would be power consumption but between the larger battery
size you tend to have on a tablet and the power draw of the
screen if that's on it's likely to be into the noise practially
speaking.

It does. Headset is Mic Jack + Headphones combined. headset_check function
performs check for a Mic Jack component in plugged Jack 3.5

This is how downstream handled mclk rate for RT5631.

That doesn't mean it shouldn't be fixed or improved.

I feel if we need to discuess what a comment means or if it even means
anything then that's a useless comment by definition.

If the device doesn't have a distinct mic jack then it's not ideal to
talk about there being one (as opposed to the microphone on the headset
jack).
