2021-12-16soc/tegra: pmc: Add reboot notifierJon Hunter
The Tegra PMC driver implements a restart handler that supports Tegra specific reboot commands such as placing the device into 'recovery' mode in order to reprogram the platform. This is accomplished by setting the appropriate bit in the PMC scratch0 register prior to rebooting the platform. For Tegra platforms that support PSCI or EFI, the default Tegra restart handler is not called and the PSCI or EFI restart handler is called instead. Hence, for Tegra platforms that support PSCI or EFI, the Tegra specific reboot commands do not currently work. Fix this by moving the code that programs the PMC scratch0 register into a separate reboot notifier that will always be called on reboot.

2021-12-16soc/tegra: Don't print error message when OPPs not availableDmitry Osipenko
Previously we assumed that devm_tegra_core_dev_init_opp_table() will be used only by drivers that will always have device with OPP table, but this is not true anymore. For example now Tegra30 will have OPP table for PWM, but Tegra20 not and both use the same driver. Hence let's not print the error message about missing OPP table in the common helper, we can print it elsewhere.

2021-12-16net: prestera: flower template supportVolodymyr Mytnyk
Add user template explicit support. At this moment, max TCAM rule size is utilized for all rules, doesn't matter which and how much flower matches are provided by user. It means that some of TCAM space is wasted, which impacts the number of filters that can be offloaded. Introducing the template, allows to have more HW offloaded filters by specifying the template explicitly. Example: tc qd add dev PORT clsact tc chain add dev PORT ingress protocol ip \ flower dst_ip 0.0.0.0/16 tc filter add dev PORT ingress protocol ip \ flower skip_sw dst_ip 1.2.3.4/16 action drop NOTE: chain 0 is the default chain id for "tc chain" & "tc filter" command, so it is omitted in the example above. This patch adds only template support for default chain 0 suppoerted by prestera driver at this moment. Chains are not supported yet, and will be added later.

2021-12-16gve: Add optional metadata descriptor type GVE_TXD_MTDWillem de Bruijn
Allow drivers to pass metadata along with packet data to the device. Introduce a new metadata descriptor type * GVE_TXD_MTD This descriptor is optional. If present it immediate follows the packet descriptor and precedes the segment descriptor. This descriptor may be repeated. Multiple metadata descriptors may follow. There are no immediate uses for this, this is for future proofing. At present devices allow only 1 MTD descriptor. The lower four bits of the type_flags field encode GVE_TXD_MTD. The upper four bits of the type_flags field encodes a *sub*type. Introduce one such metadata descriptor subtype * GVE_MTD_SUBTYPE_PATH This shares path information with the device for network failure discovery and robust response: Linux derives ipv6 flowlabel and ECMP multipath from sk->sk_txhash, and updates this field on error with sk_rethink_txhash. Allow the host stack to do the same. Pass the tx_hash value if set. Also communicate whether the path hash is set, or more exactly, what its type is. Define two common types GVE_MTD_PATH_HASH_NONE GVE_MTD_PATH_HASH_L4 Concrete examples of error conditions that are resolved are mentioned in the commits that add sk_rethink_txhash calls. Such as commit 7788174e8726 ("tcp: change IPv6 flow-label upon receiving spurious retransmission"). Experimental results mirror what the theory suggests: where IPv6 FlowLabel is included in path selection (e.g., LAG/ECMP), flowlabel rotation on TCP timeout avoids the vast majority of TCP disconnects that would otherwise have occurred during link failures in long-haul backbones, when an alternative path is available. Rotation can be applied to various bad connection signals, such as timeouts and spurious retransmissions. In aggregate, such flow level signals can help locate network issues.

2021-12-16Merge branch 'phylink-pcs-validation'David S. Miller
Russell King says: ==================== net: phylink: add PCS validation This series allows phylink to include the PCS in its validation step. There are two reasons to make this change: 1. Some of the network drivers that are making use of the split PCS support are already manually calling into their PCS drivers to perform validation. E.g. stmmac with xpcs. 2. Logically, some network drivers such as mvneta and mvpp2, the restriction we impose in the validate() callback is a property of the "PCS" block that we provide rather than the MAC. This series: 1. Gives phylink a mechanism to query the MAC driver which PCS is wishes to use for the PHY interface mode. This is necessary to allow the PCS to be involved in the validation step without making changes to the configuration. 2. Provide a pcs_validate() method that PCS can implement. This follows a similar model to the MAC's validate() callback, but with some minor differences due to observations from the various implementations. E.g. returning an error code for not-supported and the way the advertising bitmap is masked. 3. Convert mvpp2 and mvneta to this as examples of its use. Further Conversions are in the pipeline, including for stmmac+xpcs, as well as some DSA drivers. Note that DSA conversion to this is conditional upon all DSA drivers populating their supported_interfaces bitmap, since this is required before mac_select_pcs() can be used. Existing drivers that set a PCS in mac_prepare() or mac_config(), or shortly after phylink_create() will continue to work. However, it should be noted that mac_select_pcs() will be called during phylink_create(), and thus any PCS returned by mac_select_pcs() must be available by this time - or we drop the check in phylink_create(). v2: fix kerneldoc typo in patch 1. ==================== Signed-off-by: David S.

Phylink will also use this to select the PCS to be used during a major configuration event without the MAC driver needing to call phylink_set_pcs(). Note that if mac_select_pcs() is present, the supported_interfaces bitmap must be filled in; this avoids mac_select_pcs() being called with PHY_INTERFACE_MODE_NA when we want to get support for all interface types.

Eqos ethernet support five queues on hardware, enable these queues and configure the priority of each queue. Uses Strict Priority as scheduling algorithms to ensure that the TSN function works. The priority of each queue is a bitmask value that maps VLAN tag priority to the queue. Since the hardware only supports five queues, this patch maps priority 0-4 to queues one by one, and priority 5-7 to queue 4. The total fifo size of 5 queues is 8192 bytes, if enable 5 queues with store-and-forward mode, it's not enough for large packets, which would trigger fifo overflow frequently. This patch set DMA to thresh mode to enable all 5 queues.

2021-12-16arm64: dts: ls1028a-qds: add overlays for various serdes protocolsAlex Marginean
Add overlays for various serdes protocols on LS1028A QDS board using different PHY cards. These should be applied at boot, based on serdes configuration. If no overlay is applied, only the RGMII interface on the QDS is available in Linux. Building device tree fragments requires passing the "-@" argument to dtc, which increases the base dtb size and might cause some platforms to fail to store the new binary. To avoid that, it would be nice to only pass "-@" for the platforms where fragments will be used, aka LS1028A-QDS. One approach suggested by Rob Herring is used here: https://lore.kernel.org/patchwork/patch/821645/ Also moved the enet* override nodes in dts file to be in alphabetic order.

The i2c rtc is on i2c2 bus not i2c1 bus, so fix it in dts. Signed-off-by: Biwen Li <biwen.li@nxp.com> Signed-off-by: Li Yang <leoyang.lil@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2021-12-16arm64: dts: ls1028a: add ftm_alarm1 node to be used as wakeup sourceBiwen Li
Add flextimer2 based ftm_alarm1 node and enable it to be the default rtc wakeup source for rdb and qds boards instead of the original flextimer1 which is used by PWM. The ftm_alarm0 node hence is disabled by default. Signed-off-by: Biwen Li <biwen.li@nxp.com> Signed-off-by: Li Yang <leoyang.li@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
