Subject: [RFC,net-next,v1, 0/1] Enable SERDES power up/down
Date: Sun, 22 Mar 2020 21:23:41 +0800 [thread overview]
Message-ID: <20200322132342.2687-1-weifeng.voon@intel.com> (raw)
This patch is to enable Intel SERDES power up/down sequence. The SERDES
converts 8/10 bits data to SGMII signal.
1. Two new files intel_serdes.c and intel.h have been created to include
the power up/down logic.
2. Platform data has_serdes is created to identify HW system that requires
SERDES for SGMII mode. Expecting all Intel HW system will require it.
The identification logic is added in hwif.
3. A new stmmac_serdes_ops struct is introduced as helpers to program
SERDES.
