Add audio driver for rk817 upstream

I'm wondering if you all can help me.  I'm trying to get the rk817
codec driver working from Rockchip's BSP kernel sources (GPL per
the license) and I'm struggling with a few parts. The first part
is I'm not sure if I have my audio paths set up correctly. For example
the sinks I have set up are for HPOL and HPOR, and the source is for
MIC. While this does work (audio output seems fine) I'm having issues
with the GPIO to detect headphone insertion. When I insert headphones
I expect the audio to output to the headphones, and when I remove
headphones I expect the audio to output to a speaker. Right now I
have to manually change the output between the different paths.
Additionally, while the codec "technically" has dual channel inputs
for the microphone, I'm only using the L channel. Should I have a
stereo mixer? Note that I'm using the simple-audio-card to set my
paths, widgets, and the gpio pin. They all work, just not seamlessly
together.

Basically, I'm wanting to know if and how I should set up my audio
paths for the speaker and headphones, they use mostly the same pins
and only really differ in setting the external amp settings.
Additionally, once I set up my paths how do I ensure that the GPIO
events will result in switching between the speaker/headphone path?

Any help you can provide is appreciated. This is my first attempt at
something of this magnitude (for me it's a big step), even if it's
just trying to facilitate in getting a vendor's code ready for upstream.

Thank you.

is to Cc: audio maintainers (Takashi Iwai and Mark Brown).

Then you need to make sure there is a Signed-off-by tag from the 
original contribution this code is based on, along with yours. It 
doesn't hurt to have a pointer to that code either in the commit message.

You don't necessarily have to do everything at the kernel level, it's 
not uncommon to have the driver set a kcontrol for jack detection, and 
let userspace change settings on a jack detection event. PulseAudio 
relies on UCM JackControl to switch to Headphones and Headset devices.

it's uncommon to see this, use either int or u32/u64 if your require a 
specific size.

'pre' as in 'previous' or 'preamp' or as opposed to 'post'?

these sequences look like trying to bypass DAPM or re-invent it with 
custom state machines.

you will need DT bindings for all these properties.

humm, that looks like a bug. If you used devm_soc_register_component() 
in the probe, you don't need to release it here manually?
