^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)  * @dynamic_clk:	True means that the clock will be dynamically
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)  *			adjusted. Static clock otherwise.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16)  * @enable_merr_cfg:	Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG.
