[PATCH for-7.1 08/11] hw/net: Add NPCM8XX PCS Module |
|
Date: |
Tue, 5 Apr 2022 15:36:37 -0700 |
The PCS exists in NPCM8XX's GMAC1 and is used to control the SGMII
PHY. This implementation contains all the default registers and
the soft reset feature that are required to load the Linux kernel
driver. Further features have not been implemented yet.
