A "real" driver for this hardware is now in the wireless-drivers-next tree, to be merged in the next major kernel release, so this staging driver can now be deleted as it is not needed anymore. Note, 2 .h files remain for this driver, as they are referenced in a separate staging driver. That mess will be cleaned up in a follow-on patch.

2019-05-01ACPI / property: fix handling of data_nodes in acpi_get_next_subnode()Pierre-Louis Bossart
When the DSDT tables expose devices with subdevices and a set of hierarchical _DSD properties, the data returned by acpi_get_next_subnode() is incorrect, with the results suggesting a bad pointer assignment. The parser works fine with device_nodes or data_nodes, but not with a combination of the two. The problem is traced to an invalid pointer used when jumping from handling device_nodes to data nodes. The existing code looks for data nodes below the last subdevice found instead of the common root. Fix by forcing the acpi_device pointer to be derived from the same fwnode for the two types of subnodes. This same problem of handling device and data nodes was already fixed in a similar way by 'commit bf4703fdd166 ("ACPI / property: fix data node parsing in acpi_get_next_subnode()")' but broken later by 'commit 34055190b19 ("ACPI / property: Add fwnode_get_next_child_node()")', so this should probably go to linux-stable all the way to 4.12 Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Rafael J.

Andrew Lunn says: ==================== Convert mv88e6060 to mdio device This patchset builds upon the previous patches to mv88e6060. It adds support for probing the switch as an MDIO device and then removes the legacy probe method. Since this is the last device supporting legacy probe, this allows legacy probe to be removed, originally planned to be removed in 4.17, but took a bit longer. This change to the mv88e6060 is more risky than the previous patchset. Some attempts to test it have been made, by hacking the driver to match on an mv88e6352 so that it probes. These changes are all about probe, so it is a reasonable test. But testing on a real mv88e6060 would be great. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Vladimir Oltean says: ==================== Improvements to DSA core VLAN manipulation In preparation of submitting the NXP SJA1105 driver, the Broadcom b53 and Mediatek mt7530 drivers have been found to apply some VLAN workarounds that are needed in the new driver as well. Therefore this patchset is mostly simply promoting the DSA driver workarounds for VLAN to the generic code. The b53 driver was applying a few workarounds in order to convince DSA that its vlan_filtering setting is not really per-port. This is now simply set by the driver via a DSA variable at probe time. The sja1105 driver will be a second user of this. The mt7530 was also keeping track of when the .port_vlan_filtering callback was being called. Remove the kept state from this driver and simplify dealing with vlan_filtering in the generic case.

The current behavior is not as obvious as one would assume (which is that, if the driver set vlan_filtering_is_global = 1, then checking any dp->vlan_filtering would yield the same result).

2019-04-30net: dsa: Unset vlan_filtering when ports leave the bridgeVladimir Oltean
When ports are standalone (after they left the bridge), they should have no VLAN filtering semantics (they should pass all traffic to the CPU). Currently this is not true for switchdev drivers, because the bridge "forgets" to unset that. Normally one would think that doing this at the bridge layer would be a better idea, i.e. call br_vlan_filter_toggle() from br_del_if(), similar to how nbp_vlan_init() is called from br_add_if(). However what complicates that approach, and makes this one preferable, is the fact that for the bridge core, vlan_filtering is a per-bridge setting, whereas for switchdev/DSA it is per-port. Also there are switches where the setting is per the entire device, and unsetting vlan_filtering one by one, for each leaving port, would not be possible from the bridge core without a certain level of awareness. So do this in DSA and let drivers be unaware of it.

2019-04-30net: dsa: b53: Let DSA handle mismatched VLAN filtering settingsVladimir Oltean
The DSA core is now able to do this check prior to calling the .port_vlan_filtering callback, so tell it that VLAN filtering is global for this particular hardware.

2019-04-30net: dsa: Be aware of switches where VLAN filtering is a global settingVladimir Oltean
On some switches, the action of whether to parse VLAN frame headers and use that information for ingress admission is configurable, but not per port. Such is the case for the Broadcom BCM53xx and the NXP SJA1105 families, for example. In that case, DSA can prevent the bridge core from trying to apply different VLAN filtering settings on net devices that belong to the same switch.

2019-04-30net: dsa: Store vlan_filtering as a property of dsa_portVladimir Oltean
This allows drivers to query the VLAN setting imposed by the bridge driver directly from DSA, instead of keeping their own state based on the .port_vlan_filtering callback.

The size checks in vmx_nested_state are wrong because the calculations are made based on the size of a pointer to a struct kvm_nested_state rather than the size of a struct kvm_nested_state.
