* The default cluster table is based on the assumption that the PLLCA55 clock
* frequency is set to 1.7GHz. The PLLCA55 clock frequency can be set to
* 1.7/1.6/1.5/1.1 GHz based on the BOOTPLLCA_0/1 pins (and additionally can be
* clocked to 1.8GHz as well). The table below should be overridden in the board
* DTS based on the PLLCA55 clock frequency.
