I2C sub-system

Ivan-Velickovic commented 7 months ago

[x] REQ_BUF_CLIENT and REQ_BUF_ADDR should be part of the shared ring buffer protocol instead as metadata.
[x] Too many files exist, it should really just be driver.c and server.c
[x] Clean up example system description file - lots of unused memory regions, needs comments as well
[ ] Getting timeout IRQs way too frequently - these should never happen if everything is going smoothly to my understanding.
[x] The I2C server needs to be fully designed and implemented. Right now the client talks directly to the driver.
[x] Remove all @ivanv notes. ~~* [ ] Currently the I2C driver is responsible for setting up the clocks, etc. This is obviously wrong and should be done in pinctrl/regulator/clock drivers. However, this is not something we have right now.~~
[ ] Should we abstract over doing things like writing to an I2C bus (e.g setting up all the transaction tokens)
[x] We should write a little client side API for claiming and release a bus. ~~sDDF I2C example should use queue Makefile~~ no more queue.c, no more Makefile!

[x] Timer driver integrated so we're not busy-waiting
[x] Figure out that extra response dequeue when we read_response
[ ] What to do about just copying libco into the source
[x] More error-checking and cleanup is needed
[x] We are running out of return buffers fairly quickly, we must have a leak somewhere.
[x] Remove all warnings when compiling the example.

[ ] The documentation is a great start but is a bit too verbose and needs to be consistent with the implementation.
[x] Need picture of card-reader working and exactly what card reader is used (with links)
[x] Need to document that the card-reader client code is based of the Arduino PN532 library.

Card reader is the one giving the timeout interupts not the ds3231.

the zig make file needs updating
