/**
* Background
*
* This file is for the MSPI related, but not Flash driver related registers, these registers:
* - may influence both Flash and PSRAM
* - not related or directly related to Flash controller driver
*
* Some hints for naming convention:
* - For MSPI timing tuning related registers, the LL should start with `mspi_timing_ll_`
* - For others, the LL should start with `mspi_ll_`
