Okay, will do. I really am at a loss at understanding all the rules in
the whole device tree world. I just tried to follow
Documentation/powerpc and what is already present in the kernel.

There only one PTP clock. Its registers repeat in each port's memory
space, but you are only supposed to touch the first set of PTP
registers. If you consider how PTP works, there can never be per port
clocks, since this would make it impossible to make a boundary clock,
for example.
The whole idea of this PTP clock framework is to keep the clock
drivers separate from the MAC drivers, even when they use the same
hardware. The functionality is logically divided into two parts. The
MAC provides time stamps, and the clock provides a way to control its
offset and frequency.
Up until this point, people have simply hacked new private ioctls into
the driver for each MAC that supports PTP. That is not a good long
term solution for PTP support in Linux.
In general, I think it will not be hard to keep the MAC and the clock
drivers from stepping on each other's toes. The eTSEC hardware is
certainly able to be used in this way.

There are no differences (that I know of) in how the PTP clocks
work. I have in house the mpc8313, the mpc8572, and the p2020. The
mpc8572 appears to lack some of the TMR_CTRL bits, but this is
probably a documentation bug. I will check it.

The names come from the register mnemonics from the documentation. I
prefer to use the same names as is found in the manuals. That way, a
person working with docu in hand will have an easier job.

Okay, but must I then change the following code in order to find them?
Does adding the prefix just mean that I also add it to my search
strings, or is it preprocessed (stripped) somehow?
static int get_of_u32(struct device_node *node, char *str, u32 *val)
{
int plen;
const u32 *prop = of_get_property(node, str, &plen);
if (!prop || plen != sizeof(*prop))
return -1;
*val = *prop;
return 0;
}
...
if (get_of_u32(node, "tclk_period",&etsects->tclk_period) ||
get_of_u32(node, "tmr_prsc",&etsects->tmr_prsc) ||
get_of_u32(node, "tmr_add",&etsects->tmr_add) ||
get_of_u32(node, "cksel",&etsects->cksel) ||
get_of_u32(node, "tmr_fiper1",&etsects->tmr_fiper1) ||
get_of_u32(node, "tmr_fiper2",&etsects->tmr_fiper2))
return -ENODEV;

The values are related to the board. One important parameter is the
input clock, and the rest reflect some engineering decisions/tradeoffs
related to the signals to and from the PTP clock. There is not just
one "optimal" choice, so I wanted to let the designer set the
values. In any case, the parameters are definitely related to the
board (not to the cpu or to linux), so I think the device tree is the
right place for them.
> This one has 3 interrupts? The driver supports only two.
The documentation does not specify the IRQ line that each event
belongs to. After some trial and error, it appears that all of the
ancillary clock interrupts arrive on the first interrupt. The other
lines (one per port) must be for the Tx/Rx packet time stamp
indication, but we don't need these for the clock or for the MAC.
I'll just reduce the driver to one interrupt.

The 'gianfar_clock' variable holds the returned instance from the
class driver, while 'the_clock' is the driver's private data (and
there can only be one driver).
I'll combine these into one struct to make it more clear and less
funny sounding.

No, I only want to match with the eTSEC clock device. Given the
compatible string above ("fsl,etsec-ptp"), what is the correct way to
do this? (pointer to an existing driver to emulate would be enough)
Thanks for your help,

* [PATCH] pegasus: fix USB device ID for ETX-US2
From: Tadashi Abe @ 2010-05-17 8:19 UTC (permalink / raw)
To: davem; +Cc: netdev
USB device ID definition for I-O Data ETX-US2 is wrong.
Correct ID is 0x093a. Here's snippet from /proc/bus/usb/devices;
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=ff(vend.) Sub=ff Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=04bb ProdID=093a Rev= 1.01
S: Manufacturer=I-O DATA DEVICE,INC.
S: Product=I-O DATA ETX2-US2
S: SerialNumber=A26427
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=224mA
I:* If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=00 Driver=pegasus
E: Ad=81(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 8 Ivl=125us
This patch enables pegasus driver to work fine with ETX-US2.

Not necessarly. RPS is the "poor man solution", when multique NICS are
not available, or a refinement over it on special cases.
I would say 2.6.33.4 or 2.6.34 would be ok.

I believe both of us (Eilong and me) stated your kernel version was too
old.
In order to play with multiqueue, you should use a very recent kernel,
or hit various bottlenecks and bugs.

Thanks again for the status report.
I see bug is older than what I stated in my previous mail
I could reproduce it in my lab and confirm following patch fixes it
This is a stable candidate (2.6.27 kernels)
Thanks
[PATCH] tcp: tcp_synack_options() fix
Commit 33ad798c924b4a (tcp: options clean up) introduced a problem
if MD5+SACK+timestamps were used in initial SYN message.
Some stacks (old linux for example) try to negotiate MD5+SACK+TSTAMP
sessions, but since 20 bytes of tcp options space are not enough to
store all the bits needed, we chose to disable timestamps in this case.
We send a SYN-ACK _without_ timestamp option, but socket has timestamps
enabled and all further outgoing messages contain a TS block, all with
the initial timestamp of the remote peer.
Fix is to really disable timestamps option for the whole session.

I had a couple of stupid bugs in:
netns: Teach network device kobjects which namespace they are in.
- I duplicated the Kconfig for the NET_NS
- The build was broken when sysfs was not compiled in
The sysfs breakage is because after I moved the operations
for the sysfs to the kobject layer, to make things cleaner
I forgot to move the ifdefs. Opps.
I'm not quite certain how I got introduced a second NET_NS Kconfig,
but it was probably a 3 way merge somewhere along the way that
did not notice that the NET_NS Kconfig option had mvoed and thout
that was a bug. It probably slipped in because it used to be the
sysfs patches were the first patches in my network namespace patches.
Some things just don't go like you would expect.
Neither of these bugs actually affect anything in the common case
but they should be fixed.
Thanks to Serge for noticing they were present.

To: David S. Miller; +Cc: Eric Dumazet, netdev, Changli Gao
remove useless union keyword in rtable, rt6_info and dn_route.
Since there is only one member in a union, the union keyword isn't useful.

I am on quite an old kernel 2.6.27 and could not apply your patches.
Then i moved on to the kernel 2.6.32.11 however since then I have not been able to bring up my card, this is something i need to fix before i can test you fix. Working on that.
