AM335x PRU ICSS Registers Field Descriptions

Please tell me the PRU ICSS Registers Field Descriptions.

There are not the Field Descriptions of the registers except the CFG Registers in the Reference Guide.

AM335x PRU-ICSS Reference Guide
https://github.com/beagleboard/am335x_pru_package/blob/master/am335xPruReferenceGuide.pdf
3 PRU-ICSS Register Overview
10 CFG

Because our customer uses no TLK105/TLK106/TLK110 as PHY they want to configure the MDIO Registers.
