[PATCH 1/3] phy: marvell: cp110: let the firmware configure the comphy
Baruch Siach
baruch at tkos.co.il
Sun Oct 18 16:11:11 CEST 2020
From: Grzegorz Jaszczyk <jaz at semihalf.com>
Replace all comphy initialization with appropriate smc calls. It will
result with triggering synchronous exception that is handled by Secure
Monitor code in EL3. Then the Secure Monitor code will dispatch each smc
call (by parsing the smc function identifier) and triggers appropriate
comphy initialization.
This patch reworks serdes handling for: SATA, SGMII, HS-SGMII and SFI
interfaces.
