layerscape: remove useless pairs of kernel patches
The layerscape kernel patches appears to be just some uncleaned local
development tree, where patches are sometimes directly followed by
their revert. While this does not seem a problem in the first place,
it becomes incredibly unpleasant when the upstream kernel changes in
the relevant areas and requires rebase.
This removes all these patch-revert pairs and refreshs the rest.
It removes about 44000 lines of entirely useless code.

The uBUS1 and uBUS2 slots that share this interrupt line with the - Ethernet PHYs are not pulled up by default, they are left floating on - current revisions of the LS1028A-RDB boards.

The registration code is -local to the VSC7514, but the PHYLINK callback implementation is common -so that the Felix DSA front-end can use it as well (but DSA does its own -registration). - -Now Felix can use native PHYLINK callbacks instead of the PHYLIB -adaptation layer in DSA, which had issues supporting fixed-link slave -ports (no struct phy_device to pass to the adjust_link callback), as -well as fixed-link CPU port at 2.5Gbps. - -The old code from ocelot_port_enable and ocelot_port_disable has been -moved into ocelot_phylink_mac_link_up and ocelot_phylink_mac_link_down. - -The PHY connect operation has been moved from ocelot_port_open to -mscc_ocelot_probe in ocelot_board.c. - -The phy_set_mode_ext() call for the SerDes PHY has also been moved into -mscc_ocelot_probe from ocelot_port_open, and since that was the only -reason why a reference to it was kept in ocelot_port_private, that -reference was removed. - -Again, the usage of phy_interface_t phy_mode is now local to -mscc_ocelot_probe only, after moving the PHY connect operation. -So it was also removed from ocelot_port_private. -*Maybe* in the future, it can be added back to the common struct -ocelot_port, with the purpose of validating mismatches between -state->phy_interface and ocelot_port->phy_mode in PHYLINK callbacks. -But at the moment that is not critical, since other DSA drivers are not -doing that either. No SFP+ modules are in use with Felix/Ocelot yet, to -my knowledge. - -In-band AN is not yet supported, due to the fact that this is a mostly -mechanical patch for the moment. The mac_an_restart PHYLINK operation -needs to be implemented, as well as mac_link_state. Both are SerDes -specific, and Felix does not have its PCS configured yet (it works just -by virtue of U-Boot initialization at the moment). - -Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> ---- - drivers/net/dsa/ocelot/felix.c | 65 +++++++++---- - drivers/net/ethernet/mscc/Kconfig | 2 +- - drivers/net/ethernet/mscc/ocelot.c | 150 ++++++++++++++++-------------- - drivers/net/ethernet/mscc/ocelot.h | 13 +-- - drivers/net/ethernet/mscc/ocelot_board.c | 154 +++++++++++++++++++++++++++---- - include/soc/mscc/ocelot.h | 22 ++++- - 6 files changed, 289 insertions(+), 117 deletions(-) - ---- a/drivers/net/dsa/ocelot/felix.c -+++ b/drivers/net/dsa/ocelot/felix.c -@@ -58,14 +58,6 @@ static int felix_set_ageing_time(struct - return 0;
