On the T208X SoCs, MAC1 and MAC2 support XGMII. Add some new MAC dtsi
fragments, and mark the QMAN ports as 10G.

Fixes: da414bb923d9 ("powerpc/mpc85xx: Add FSL QorIQ DPAA FMan support to the SoC device tree(s)")

Hi Sean,

These changes prevent MAC2 from probing on T2080RDB due to insufficient FMan hardware resources.

fsl-fman ffe400000.fman: set_num_of_tasks: Requested num_of_tasks and extra tasks pool for fm0 exceed total num_of_tasks.
fsl_dpa: dpaa_eth_init_tx_port: fm_port_init failed
fsl_dpa: probe of dpaa-ethernet.5 failed with error -11

The distribution of resources depends on the port type, and different FMan hardware revisions have different amounts of resources.

The current distribution of resources can be reconsidered, but this change should be reverted for now.

Regards,
Camelia

OK, so this patch does two things:

First, it marks the ports as 10g. I believe this is what's causing the
resource problems above. Second, it removes support for QSGMII and adds
support for XFI. This is a matter of correctness; these MACs really
don't support QSGMII, and do support XFI. As I understand it, you can
run a 10g port at 1g speeds, it just won't perform as well. So I think a
more minimal revert would be to delete the fsl,fman-10g-port properties
in t2081si-post.dtsi.

That said, is 10g even being used on these ports? I included this patch
in order to avoid breaking any existing users.

That's right.

Correct, these MACs don't support QSGMII on this SoC.

Since these two new dtsi files are included by only one SoC, I don't see an
advantage in adding these properties and then deleting them. No other
users benefit from adding them in the first place.

It is used, though less efficiently, with fewer FMan hardware resources.

OK, so would you prefer just overriding pcs-handle-names in the SoC dtsi?
