Message-ID: <20190501193126.19196-6-rasmus.villemoes@prevas.dk> Date: Wed, 1 May 2019 19:32:14 +0000 From: Rasmus Villemoes <rasmus.villemoes@...vas.dk> To: Andrew Lunn <andrew@...n.ch>, Vivien Didelot <vivien.didelot@...oirfairelinux.com> CC: "netdev@...r.kernel.org" <netdev@...r.kernel.org>, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>, "David S. Miller" <davem@...emloft.net>, Florian Fainelli <f.fainelli@...il.com>, Rasmus Villemoes <Rasmus.Villemoes@...vas.se> Subject: [RFC PATCH 5/5] net: dsa: add support for mv88e6250 This is a very rough attempt at adding support for the Marvell 88E6250. The _info and _ops structures are based on those for 6240 (as I have data sheets for both the 6240 and 6250), fixing the things that I have determined to be different for the two chips - but some things are almost certain to still be wrong. The chip uses the new dual_chip option, and since its port registers start at SMI address 0x08 or 0x18 (i.e., always 0x08 + sw_addr), we need to introduce it as a new family in order for the auto-identification in mv88e6xxx_detect() to work.
