Vladimir Oltean 21ce7f3e16 net: dsa: ocelot: the MAC table on Felix is twice as large
When running 'bridge fdb dump' on Felix, sometimes learnt and static MAC
addresses would appear, sometimes they wouldn't.

Turns out, the MAC table has 4096 entries on VSC7514 (Ocelot) and 8192
entries on VSC9959 (Felix), so the existing code from the Ocelot common
library only dumped half of Felix's MAC table. They are both organized
as a 4-way set-associative TCAM, so we just need a single variable
indicating the correct number of rows.

Yangbo Lu cc2d87bb83 net: mscc: ocelot: support 4 PTP programmable pins
Support 4 PTP programmable pins with only PTP_PF_PEROUT function
for now. The PTP_PF_EXTTS function will be supported in the
future, and it should be implemented separately for Felix and
Ocelot, because of different hardware interrupt implementation
in them.

Since the hardware is not able to support absolute start time,
the periodic clock request only allows start time 0 0. But nsec
could be accepted for PPS case for phase adjustment.

Yangbo Lu 2b49d128b3 net: mscc: ocelot: move ocelot ptp clock code out of ocelot.c
The Ocelot PTP clock driver had been embedded into ocelot.c driver.
It had supported basic gettime64/settime64/adjtime/adjfine functions
by now which were used by both Ocelot switch and Felix switch.

This patch is to move current ptp clock code out of ocelot.c driver
maintaining as a single ocelot_ptp.c.
For futher new features implementation, the common code could be put
in ocelot_ptp.c and the switch specific code should be in specific
switch driver. The interrupt implementation in SoC is different
between Ocelot and Felix.

Vladimir Oltean 87b0f983f6 net: mscc: ocelot: fix untagged packet drops when enslaving to vlan aware bridge
To rehash a previous explanation given in commit 1c44ce560b ("net:
mscc: ocelot: fix vlan_filtering when enslaving to bridge before link is
up"), the switch driver operates the in a mode where a single VLAN can
be transmitted as untagged on a particular egress port. That is the
"native VLAN on trunk port" use case.

The configuration for this native VLAN is driven in 2 ways:
 - Set the egress port rewriter to strip the VLAN tag for the native
   VID (as it is egress-untagged, after all).
 - Configure the ingress port to drop untagged and priority-tagged
   traffic, if there is no native VLAN. The intention of this setting is
   that a trunk port with no native VLAN should not accept untagged
   traffic.

Since both of the above configurations for the native VLAN should only
be done if VLAN awareness is requested, they are actually done from the
ocelot_port_vlan_filtering function, after the basic procedure of
toggling the VLAN awareness flag of the port.

But there's a problem with that simplistic approach: we are trying to
juggle with 2 independent variables from a single function:
 - Native VLAN of the port - its value is held in port->vid.
 - VLAN awareness state of the port - currently there are some issues
   here, more on that later*.
The actual problem can be seen when enslaving the switch ports to a VLAN
filtering bridge:
 0. The driver configures a pvid of zero for each port, when in
    standalone mode. While the bridge configures a default_pvid of 1 for
    each port that gets added as a slave to it.
 1. The bridge calls ocelot_port_vlan_filtering with vlan_aware=true.
    The VLAN-filtering-dependent portion of the native VLAN
    configuration is done, considering that the native VLAN is 0.
 2. The bridge calls ocelot_vlan_add with vid=1, pvid=true,
    untagged=true. The native VLAN changes to 1 (change which gets
    propagated to hardware).
 3. ??? - nobody calls ocelot_port_vlan_filtering again, to reapply the
    VLAN-filtering-dependent portion of the native VLAN configuration,
    for the new native VLAN of 1. One can notice that after toggling "ip
    link set dev br0 type bridge vlan_filtering 0 && ip link set dev br0
    type bridge vlan_filtering 1", the new native VLAN finally makes it
    through and untagged traffic finally starts flowing again. But
    obviously that shouldn't be needed.

So it is clear that 2 independent variables need to both re-trigger the
native VLAN configuration. So we introduce the second variable as
ocelot_port->vlan_aware.

*Actually both the DSA Felix driver and the Ocelot driver already had
each its own variable:
 - Ocelot: ocelot_port_private->vlan_aware
 - Felix: dsa_port->vlan_filtering
but the common Ocelot library needs to work with a single, common,
variable, so there is some refactoring done to move the vlan_aware
property from the private structure into the common ocelot_port
structure.

Dmitry Osipenko 860fbde438 cpuidle: Refactor and move out NVIDIA Tegra20 driver into drivers/cpuidle
The driver's code is refactored in a way that will make it easy to
support Tegra30/114/124 SoCs by this unified driver later on. The
current functionality is equal to the old Tegra20 driver, only the
code's structure changed a tad. This is also a proper platform driver
now.

Venkat Reddy Talla 04fac2412b soc/tegra: pmc: Add pins for Tegra194
Extend the Tegra194 IO pad table with additional information such as pin
names and 1.8/3.3 V settings to allow a table of voltage control pins to
generated from it. This is similar to what's done for older chips and is
needed to support high-speed modes for SDHCI where switching the pins to
1.8V or 3.3V is necessary.
