fast ethernet LXT972A support
Hi, I'm using the LXT971 settings for an LXT972 on a 857 board and It's running fine...

That's what I was looking at, too. But you mentioned "latest kernel", and I have here: revision 1.20 date: 2002/08/11 11:09:33; author: wd; state: Exp; lines: +369 -42 1. Added support for PHY DP83843BVJE. 2. Added support for PHY DP83846A. 3. Added a timer callback to periodically probe the DP83846A (or any other chip, it is easy to adapt) for link changes. The delays are hard-coded, though. Someone could add some configuration parameters for it, of course! The periods depend on the link state: - 1 second when the link is up. - 100ms when the link is down. 4. Added the standard IOCTL support to manipulate the PHY registers. 5. A bugfix (in fec_restart(), if the flag 'tx_full' is set, it must be cleared, and the network interface queue needs to be awakened.) Based on patch by Jean-Denis Boyer , 22 Mar 2002 See http://lists.linuxppc.org/linuxppc-embedded/200203/msg00200.html For me, latest == top of CVS :-) Wolfgang Denk -- Software Engineering: Embedded and Realtime Systems, Embedded Linux Phone: (+49)-8142-4596-87 Fax: (+49)-8142-4596-88 Email: wd at denx.de The greatest threat towards future is indifference. ** Sent via the linuxppc-embedded mail list.

Ummm you must be looking in the wrong place; our kernel version supports AMD79C874, LXT970, LXT971, QS6612, DP83843, and DP83846A on MPC8xx processors, and AMD79C873, LXT970, LXT971, QS6612 on MPC8260 processors.

Does it mean that LXT972 Well, the first several lines of comments says that. ;) > Ummm you must be looking in the wrong place; our kernel version > supports AMD79C874, LXT970, LXT971, QS6612, DP83843, and DP83846A on > MPC8xx processors, and AMD79C873, LXT970, LXT971, QS6612 on MPC8260 Well, the version I got is linux-2.4.4-08-09. And I'm sure there are no DP83843 and DP83846A support. So you must have made progress in supporting new PHYs. :) The file I'm looking at is arch/ppc/8xx_io/fec.c. - Shawn. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/

After looking into LXT971/972 datasheets, I believe LXT972 can use 971's driver. Thanks. - Shawn. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/

I noticed that only LXT970 and 971 are supported in the lastest kernel distribution from DENX. But the comments in fec.c say "includes support for following PHYs: QS6612, LXT970, LXT971/2". Does it mean that LXT972 can use 971's driver? If not, basically what kind of modification is needed? Thanks. - Shawn. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
