Marcus Chang 4bb84fdb71 Change NRF52 series UART to only use one SWI channel 
This fixes conflicts with the SoftDevice.

Marcus Chang a0224ed794 Fix interrupt initialization for NRF52 series 
In some cases the UARTE interrupt would be enabled with pending
interrupts. This commit ensures that interrupts are only enabled
from a known state.

Marcus Chang fc087ab32c Fix race condition in serial_api.c for NRF52 series 
* Elevate RTC2 interrupt priority to same level as UARTE to prevent
race condition on shared variables.
* Remove unused TXDRDY event code.
* Fix typo in macro.

Marcus Chang 6346ba87c0 Improve serial performance for NRF52 series 
Time sensitive user callbacks are called through lowest priority
SWI handlers instead of the highest priority UART handler.

Marcus Chang ddc709acec Make serial_putc non-blocking for the NRF52 series 
Previous implementation would block until character had been
completely sent, which is not what the API specifies.

Marcus Chang a42f1d7a81 Remove whitespace from NRF52 serial_api.c 2018-06-25 13:16:11 -07:00
Marcus Chang 1aebdcbee5 Reorganize TARGET_MCU_NRF51822_UNIFIED directories 
The unified NRF51 target and feature BLE directories have been
reorganized to follow the naming and directory structure of the
NRF52 implementation.

This reorganization does not include TARGET_MCU_NRF51822 and
derived targets.
