aaae9bc0f2 Adding dynamic USB power support
- Each scan module now has a current change callback which passes the available current as a parameter
- No longer attempts to use the max 500 mA immediately, starts with 100 mA then goes to 500 mA after enumeration
- If enumeration fails due to bMaxPower of 500 mA, then attempt again at 100 mA (might also be possible to go even lower to 20 mA in certain cases)
- Now working with the Apple Ipad (no over-power messages)
- Fixed Wake-up behaviour on Apple Ipad (and likely other iOS devices)
- More effecient set_feature/clear_feature handling (device handler)
- Initial power handling via Interconnect (still needs work to get it more dynamic)

a25aa84513 Initial support for the ICPad
- Basic support for up to 4 ISSI chips (and partial support for 16 chip configurations)
- Initial USB mux support
  * Required USB re-init procedure
- Initial interconnect mux support
  * Required some state reset commands

a10afbcc6a Adding remote capability LED control
- Works for all nodes in chain
- Synchronized to 30 ms update rate (required for ISSI chip)
  * Interconnect cannot handle full update speed from Scan module
  * Though it should be able to handle quite a bit more than 30 ms updates

7e68e81f47 Adding basic remote capabilities + UART Rx DMA buffers
- Rx buffers weren't fast enough, had to use DMA :D
- Basic LCD remote capabilities are working, single node
- Multi-node broadcast seems to have a bug still
- DMA ring buffer allowed for significant processing simplification
  * There is an overrun risk, but the buffer is large and generally there isn't too much data being sent (just very quickly)
- Split out LCD layer stack capability into itself and an "exact" version used for updating remote nodes

a8caf6e515 Working support for Interconnect
- Supports up to 255 slave nodes (you'll run into ScanCode limitations before then)
- Requires most recent kll compiler update
- Additional debugging output and stats counters
- Noise and parity checking
- Fixed TxFIFO issue when sending buffers larger than the FIFO
- Cleaned up defaultMap.kll
- Added ScanCode caching (reduces interconnect traffic significantly)
- Interconnect module code is conditionally compiled into PartialMap module if required

ecd9923926 Initial UARTConnect scancode support
- Still some issues
- Will require some changes to MatrixARM and PartialMap
  * Currently state information is passed around too frequently
  * Needs to be reduced to state changes only

55d03f448e UARTConnect enumeration working!
- Fixed cli reflash mode set
- Cleaned up debugging code
- 4 500 000 baud seems to be reliable
- Fixed master selection (assumes slave node unless USB enumerates)

ed71f7fad5 Initial commit for UARTConnect module
* Keyboard interconnect using two uarts
* Supports daisy chain addressing using a master/slave direction communication scheme

- Still needs more testing
- Functions have been tested alone to be generally working
