i.mx6SX ENET RGMII connection

The i.mx6SX has a register called ENETx_ECR_RXC_DLY & ENETx_ECR_TXC_DLY. There is no explanation on what type (lenght) of delay it enables. Where can I find a detailed description?


The background is that I need to connect i.mx6SX RGMII port to a switch. That typically needs a tuned delay for the Tx & Rx clock's. Normally that delay is programmable on the PHY side. But since this is not connected to a PHY I need to manage the the clock delay. The mentioned register values might be able to do that but it's impossible to determine upfront if I don't know what they do exactly.
