My recommendation is to use the new nrfx driver directly as suggested in SDKv15 migration document directly when porting from sdkv14 to sdkv14.

"

For existing applications the migration to the new API in most cases will be quite simple and require only:

• renaming used functions and types from nrf_drv_* to nrfx_*,
• renaming used macros from NRF_DRV_* to NRFX_*,
• replacing old configuration options contained in "sdk_config.h" with their new versions by adding NRFX_ prefix to their names.

Best regards,
Kenneth
