Subject: Re: [PATCH v2 03/12] PCI: aardvark: Add PHY support

Message-ID: <20181217223430.182d01d8@nic.cz> (raw)

Miquel,
I tried the patches and they are working, with the exception of Compex
WLE900X card, but we know that this card is problematic.
I am interesting if there is a known way to turn of the comphy on
A3720, or at least change the SGMII mode from 1Gbps to 2.5Gbps and
back. Marvell documentation does not provide this information and the
code in ATF providing the SMC calls does not do this either.
Do you know how this can be achieved?
Thanks,
Marek
