Module nrf52::spi

Implementation of SPI for NRF52 using EasyDMA.

This file only implments support for the three SPI master (SPIM) peripherals, and not SPI slave (SPIS).

Although kernel::hil::spi::SpiMaster is implemented for SPIM, only the functions marked with x are fully defined:

• [x] set_client
• [x] init
• [x] is_busy
• [x] read_write_bytes
• [ ] write_byte
• [ ] read_byte
• [ ] read_write_byte
• [x] specify_chip_select
• [x] set_rate
• [x] get_rate
• [x] set_clock
• [x] get_clock
• [x] set_phase
• [x] get_phase
• [ ] hold_low

• [ ] release_low
