There are two kinds of dsaf device in hns, one is for service ports,
contains crossbar in it, can work under different mode. Another is for
debug port, only can work under single port mode. The current code only
declares a dsaf device for both service ports and debug ports.It is not so
readability. This patch separates it to three platform devices to make the
code more simple and readability.

We take the compatibility into consideration, and it works well by using the
old dts file(tested on d02 board).
For more details, please see individual patches.

As debug ports are moved from service dsaf to debug dsaf,
the interrupts offset should start from 0, So this patch
re-defines the offset index of debug ports.

This patch parse port-idx-in-ae in enet node. In NIC mode of DSAF, all 6
PHYs of service DSAF are taken as ethernet ports to the CPU. The
port-idx-in-ae can be 0 to 5. Here is the diagram:
+-----+---------------+
| CPU |
+-+-+-+---+-+-+-+-+-+-+
| | | | | | | |
debug debug service
port port port
(0) (0) (0-5)
In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical
ports connect to a LAN Switch while the CPU side assume itself have one
single NIC connect to this switch. In this case, the port-idx-in-ae will
be 0 only.
+-----+-----+------+------+
| CPU |
+-+-+-+-+-+-+-+-+-+-+-+-+-+
| | service| port(0)
debug debug +------------+
port port | switch |
(0) (0) +-+-+-+-+-+-++
| | | | | |
external port
when port-idx-in-ae is not exists, old attribute port-id will be used
(only for compatible purpose, not recommended to use port-id in new code).

This patch parse port-idx-in-ae in enet node. In NIC mode of DSAF, all 6
PHYs of service DSAF are taken as ethernet ports to the CPU. The
port-idx-in-ae can be 0 to 5. Here is the diagram:
+-----+---------------+
| CPU |
+-+-+-+---+-+-+-+-+-+-+
| | | | | | | |
debug debug service
port port port
(0) (0) (0-5)
In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical
ports connect to a LAN Switch while the CPU side assume itself have one
single NIC connect to this switch. In this case, the port-idx-in-ae will
be 0 only.
+-----+-----+------+------+
| CPU |
+-+-+-+-+-+-+-+-+-+-+-+-+-+
| | service| port(0)
debug debug +------------+
port port | switch |
(0) (0) +-+-+-+-+-+-++
| | | | | |
external port
when port-idx-in-ae is not exists, old attribute port-id will be used
(only for compatible purpose, not recommended to use port-id in new code).

This patch adds a new dsaf mode named "single-port" mode for debug port.
This mode only contains one debug port. This patch also changes the
method of distinguishing the port type.

This mode only contains one debug port. This patch also changes the

There are two kinds of dsaf device in hns, one is for service ports,
contains crossbar in it, can work under different mode. Another is for
debug port, only can work under "single-port" mode. The current code only
declared a dsaf device for both service ports and debug ports. This patch
separate it to three platform devices.
Here is the diagram of all port in one platform device(old):

There are two kinds of dsaf device in hns, one is for service ports,
contains crossbar in it, can work under different mode. Another is for
debug port, only can work under "single-port" mode. The current code only
declared a dsaf device for both service ports and debug ports. This patch
separate it to three platform devices.
Here is the diagram of all port in one platform device(old):

There are two kinds of dsaf device in hns, one is for service ports,
contains crossbar in it, can work under different mode. Another is for
debug port, only can work under "single-port" mode. The current code only
declared a dsaf device for both service ports and debug ports. This patch
separate it to three platform devices.
Here is the diagram of all port in one platform device(old):

The reset offset for each port in a dsaf is different. The current code is
not so readability. This patch adds configuration named port-rst-offset to
make the code simple and more readability. If this attribute doesn't exist,
default value of this attribute is equal to its port index.

Separated when? New version of the h/w? If so, where's the new
compatible string? This is quite a big binding change.

But you have up to 5 regions.
The variable nature of what regions you have tells me you need more
specific compatible strings for each chip.

Indexes should generally be avoided. What does the number correspond
to in h/w (if anything)?

This would usually be a cell in the cpld-syscon property.

Again, sounds like you need more specific compatible strings that imply
this information.

Separated when? New version of the h/w? If so, where's the new
compatible string? This is quite a big binding change.

But you have up to 5 regions.
The variable nature of what regions you have tells me you need more
specific compatible strings for each chip.

Indexes should generally be avoided. What does the number correspond
to in h/w (if anything)?

This would usually be a cell in the cpld-syscon property.

Again, sounds like you need more specific compatible strings that imply
this information.

Hi Rob and David,
Please see my comments inline.
David have merged this series to net-next, but we need to modify some codes according
to Rob's comments. I am not sure if i need to send V3 for this series, or separate
patches of documentation to independent series and generate a new patch for hns base
on current net-next?
Thanks,
Yisen

There isn't any change of h/w. I separated debug dsaf port from sevice dsaf
port to make the code more simple and readability.

we didn't add support of new h/w. We added these regions to make code simple and readability.
If we need to add support of next h/w version next time, we don't need to add many branches
for these attributes. So we didn't add a new compatible here.

port-id is index for a port in dsaf, it is correspond to index of PHY showed below.

There isn't any change of h/w. I separated debug dsaf port from sevice dsaf
port to make the code more simple and readability.

we didn't add support of new h/w. We added these regions to make code simple and readability.
If we need to add support of next h/w version next time, we don't need to add many branches
for these attributes. So we didn't add a new compatible here.

port-id is index for a port in dsaf, it is correspond to index of PHY showed below.

That's David's call. I'm guessing he wants follow-up patches on top of these.

Not sure what you mean by branches. It's fine to put properties for
things that vary among h/w versions, but new compatible strings will
be needed for any new versions.

Because debug dsaf port was separated from service dsaf port, this patch
updates the related configurations of hns dts, changes it to match with
the new binding files. This also removes enet nodes which don't exist in
d02 board.
