2020-03-24mtd: spi-nor: Set all BP bits to one when lock_len == mtd->sizeTudor Ambarus
When there are more BP settings than needed for defining the protected areas of the flash memory, most flashes will define the remaining settings as "protect all", i.e. the equivalent of having all the BP bits set to one. But there are flashes where the in-between BP values are undefined (not mentioned), and only the "all bits set" is protecting the entire memory. One such example is w25q80, where BP[2:0]=0b101 and 0b110 are not defined. Set all the BP bits to one when lock_len == mtd->size, to treat this special case.

2020-03-23net: dsa: sja1105: configure the PTP_CLK pin as EXT_TS or PER_OUTVladimir Oltean
The SJA1105 switch family has a PTP_CLK pin which emits a signal with fixed 50% duty cycle, but variable frequency and programmable start time. On the second generation (P/Q/R/S) switches, this pin supports even more functionality. The use case described by the hardware documents talks about synchronization via oneshot pulses: given 2 sja1105 switches, arbitrarily designated as a master and a slave, the master emits a single pulse on PTP_CLK, while the slave is configured to timestamp this pulse received on its PTP_CLK pin (which must obviously be configured as input). The difference between the timestamps then exactly becomes the slave offset to the master. The only trouble with the above is that the hardware is very much tied into this use case only, and not very generic beyond that: - When emitting a oneshot pulse, instead of being told when to emit it, the switch just does it "now" and tells you later what time it was, via the PTPSYNCTS register. [ Incidentally, this is the same register that the slave uses to collect the ext_ts timestamp from, too. ] - On the sync slave, there is no interrupt mechanism on reception of a new extts, and no FIFO to buffer them, because in the foreseen use case, software is in control of both the master and the slave pins, so it "knows" when there's something to collect. These 2 problems mean that: - We don't support (at least yet) the quirky oneshot mode exposed by the hardware, just normal periodic output. - We abuse the hardware a little bit when we expose generic extts. Because there's no interrupt mechanism, we need to poll at double the frequency we expect to receive a pulse. Currently that means a non-configurable "twice a second".

2020-03-23net: dsa: sja1105: make the AVB table dynamically reconfigurableVladimir Oltean
The AVB table contains the CAS_MASTER field (to be added in the next patch) which decides the direction of the PTP_CLK pin. Reconfiguring this field dynamically is highly preferable to having to reset the switch and upload a new static configuration, so we add support for exactly that.

2020-03-23net: dsa: sja1105: make future_base_time a common helperVladimir Oltean
Because the PTP_CLK pin starts toggling only at a time higher than the current PTP clock, this helper from the time-aware shaper code comes in handy here as well. We'll use it to transform generic user input for the perout request into valid input for the sja1105 hardware. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

2020-03-23net: dsa: sja1105: unconditionally set DESTMETA and SRCMETA in AVB tableVladimir Oltean
These fields configure the destination and source MAC address that the switch will put in the Ethernet frames sent towards the CPU port that contain RX timestamps for PTP. These fields do not enable the feature itself, that is configured via SEND_META0 and SEND_META1 in the General Params table. The implication of this patch is that the AVB Params table will always be present in the static config. Which doesn't really hurt. This is needed because in a future patch, we will add another field from this table, CAS_MASTER, for configuring the PTP_CLK pin function. That can be configured irrespective of whether RX timestamping is enabled or not, so always having this table present is going to simplify things a bit.

2020-03-23octeontx2-pf: Cleanup all receive buffers in SG descriptorGeetha sowjanya
With MTU sized receive buffers it is not expected to have CQE_RX with multiple receive buffer pointers. But since same physcial link is shared by PF and it's VFs, the max receive packet configured at link could be morethan MTU. Hence there is a chance of receiving plts morethan MTU which then gets DMA'ed into multiple buffers and notified in a single CQE_RX. This patch treats such pkts as errors and frees up receive buffers pointers back to hardware. Also on the transmit side this patch sets SMQ MAXLEN to max value to avoid HW length errors for the packets whose size > MTU, eg due to path MTU.

2020-03-23octeontx2-vf: Link event notification supportTomasz Duszynski
VF shares physical link with PF. Admin function (AF) sends notification to PF whenever a link change event happens. PF has to forward the same notification to each of the enabled VF. PF traps START/STOP_RX messages sent by VF to AF to keep track of VF's enabled/disabled state.

2020-03-23octeontx2-vf: Ethtool supportTomasz Duszynski
Added ethtool support for VF devices for - Driver stats, Tx/Rx perqueue stats - Set/show Rx/Tx queue count - Set/show Rx/Tx ring sizes - Set/show IRQ coalescing parameters - RSS configuration etc It's the PF which owns the interface, hence VF cannot display underlying CGX interface stats. Except for this rest ethtool support reuses PF's APIs. Signed-off-by: Tomasz Duszynski <tduszynski@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.
