- Correct definition of SPI2C_INSTANCES when using SPIM vs SPI
- Use NRFX_SPIM_XFER_TRX macro vs manually filling structure.
- Fix compile error in NRFX_SPIM_DEFAULT_EXTENDED_CONFIG where ordering of members does not match structure nrfx_spim_config_t
- Use High Drive if using SPIM3 on MOSI and SCK pins.
Also addressed:
- removed dependency on legacy config (excluded apply_old_config.h)
- removed legacy pwm and saadc headers
- Arm Compiler 5 linking issue (a band-aid for now... needs to
be properly addressed for peripheral sharing)
- added missing header in SoftDevice file
New changes to Mbed error reporting in 5.9 exposed bug in SPI
driver where an instance was uninitialized twice which triggered
an ASSERT.
This fix keeps track of which instance has been initialized and
only calls uninit when it is safe.
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.
