/**
* @note BACKGOURND:
*
* The SPI FLASH module clock and SPI PSRAM module clock is divided from the SPI core clock, core clock is from system clock:
*
* PLL ----| |---- FLASH Module Clock
* XTAL ----|----> Core Clock ---->|
* RTC8M ----| |---- PSRAM Module Clock
*
*
* DDR stands for double data rate, MSPI samples at both posedge and negedge. So the real spped will be doubled.
* Speed from high to low: 120M DDR > 80M DDR > 120 SDR > 80M SDR > ...
*
* Module with speed lower than 120M SDR doesn't need to be tuned
*
* @note LIMITATION:
* How to determine the core clock on 728. There are 2 limitations.
*
* 1. MSPI FLASH and PSRAM share the core clock register. Therefore:
* MSPI_TIMING_FLASH_EXPECTED_CORE_CLK_MHZ == MSPI_TIMING_PSRAM_EXPECTED_CORE_CLK_MHZ
*
* 2. DDR mode requires the core clock divider (core_clk / div = module_clk) to be power of 2.
