2023-06-12mmc: sdhci-msm: Switch to the new ICE APIAbel Vesa
Now that there is a new dedicated ICE driver, drop the sdhci-msm ICE implementation and use the new ICE api provided by the Qualcomm soc driver ice. The platforms that already have ICE support will use the API as library since there will not be a devicetree node, but instead they have reg range. In this case, the of_qcom_ice_get will return an ICE instance created for the consumer's device. But if there are platforms that do not have ice reg in the consumer devicetree node and instead provide a dedicated ICE devicetree node, theof_qcom_ice_get will look up the device based on qcom,ice property and will get the ICE instance registered by the probe function of the ice driver. The ICE clock is now handle by the new driver. This is done by enabling it on the creation of the ICE instance and then enabling/disabling it on SDCC runtime resume/suspend.

2023-06-12mmc: sdhci-pci-gli: Add support SD Express card for GL9767Victor Shih
Add support SD Express card for GL9767. The workflow of the SD Express card in GL9767 is as below. 1. GL9767 operates in SD mode and set MMC_CAP2_SD_EXP flag. 2. If card is inserted, Host send CMD8 to ask the capabilities of the card. 3. If the card has PCIe capability, then init_sd_express() will be invoked. 4. If the card has been put in write protect state then the SD features supported by SD mode but not supported by PCIe mode, therefore GL9767 switch to SD mode. 5. If the card has not been put in write protect state then GL9767 switch from SD mode to PCIe/NVMe mode and mmc driver handover control to NVMe driver. 6. If card is removed, GL9767 will return to SD mode.

2023-06-12mmc: sdhci: fix DMA configure compatibility issue when 64bit DMA mode is used.Chevron Li
Bayhub SD host has hardware limitation: 1.The upper 32bit address is inhibited to be written at SD Host Register [03E][13]=0 (32bits addressing) mode, is admitted to be written only at SD Host Register [03E][13]=1 (64bits addressing) mode. 2.Because of above item#1, need to configure SD Host Register [03E][13] to 1(64bits addressing mode) before set 64bit ADMA system address's higher 32bits SD Host Register [05F~05C] if 64 bits addressing mode is used. The hardware limitation is reasonable for below reasons: 1.Normal flow should set DMA working mode first, then do DMA-transfer-related configuration, such as system address. 2.The hardware limitation may avoid the software to configure wrong higher 32bit address at 32bits addressing mode although it is redundant. The change that set 32bits/64bits addressing mode before set ADMA address, has no side-effect to other host IPs for below reason: The setting order is reasonable and standard: DMA Mode setting first and then DMA address setting. It meets all DMA setting sequence.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux mlx5-updates-2023-06-09 1) Embedded CPU Virtual Functions 2) Lightweight local SFs Daniel Jurgens says: ==================== Embedded CPU Virtual Functions This series enables the creation of virtual functions on Bluefield (the embedded CPU platform). Embedded CPU virtual functions (EC VFs). EC VF creation, deletion and management interfaces are the same as those for virtual functions in a server with a Connect-X NIC. When using EC VFs on the ARM the creation of virtual functions on the host system is still supported. Host VFs eswitch vports occupy a range of 1..max_vfs, the EC VF vport range is max_vfs+1..max_ec_vfs. Every function (PF, ECPF, VF, EC VF, and subfunction) has a function ID associated with it. Prior to this series the function ID and the eswitch vport were the same. That is no longer the case, the EC VF function ID range is 1..max_ec_vfs. When querying or setting the capabilities of an EC VF function an new bit must be set in the query/set HCA cap structure. This is a high level overview of the changes made: - Allocate vports for EC VFs if they are enabled. - Create representors and devlink ports for the EC VF vports. - When querying/setting HCA caps by vport break the assumption that function ID is the same a vport number and adjust accordingly. - Create a new type of page, so that when SRIOV on the ARM is disabled, but remains enabled on the host, the driver can wait for the correct pages. - Update SRIOV code to support EC VF creation/deletion. =================== Lightweight local SFs: Last 3 patches form Shay Drory: SFs are heavy weight and by default they come with the full package of ConnectX features. Usually users want specialized SFs for one specific purpose and using devlink users will almost always override the set of advertises features of an SF and reload it. Shay Drory says: ================ In order to avoid the wasted time and resources on the reload, local SFs will probe without any auxiliary sub-device, so that the SFs can be configured prior to its full probe. The defaults of the enable_* devlink params of these SFs are set to false. Usage example: Create SF: $ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11 $ devlink port function set pci/0000:08:00.0/32768 \ hw_addr 00:00:00:00:00:11 state active Enable ETH auxiliary device: $ devlink dev param set auxiliary/mlx5_core.sf.1 \ name enable_eth value true cmode driverinit Now, in order to fully probe the SF, use devlink reload: $ devlink dev reload auxiliary/mlx5_core.sf.1 At this point the user have SF devlink instance with auxiliary device for the Ethernet functionality only. ================

2023-06-12clk: imx: composite-8m: Add imx8m_divider_determine_rateAdam Ford
Currently, certain clocks are derrived as a divider from their parent clock. For some clocks, even when CLK_SET_RATE_PARENT is set, the parent clock is not properly set which can lead to some relatively inaccurate clock values. Unlike imx/clk-composite-93 and imx/clk-divider-gate, it cannot rely on calling a standard determine_rate function, because the 8m composite clocks have a pre-divider and post-divider. Because of this, a custom determine_rate function is necessary to determine the maximum clock division which is equivalent to pre-divider * the post-divider. With this added, the system can attempt to adjust the parent rate when the proper flags are set which can lead to a more precise clock value. On the imx8mplus, no clock changes are present. On the Mini and Nano, this can help achieve more accurate lcdif clocks. When trying to get a pixel clock of 31.500MHz on an imx8m Nano, the clocks divided the 594MHz down, but left the parent rate untouched which caused a calulation error. Before: video_pll 594000000 video_pll_bypass 594000000 video_pll_out 594000000 disp_pixel 31263158 disp_pixel_clk 31263158 Variance = -236842 Hz After this patch: video_pll 31500000 video_pll_bypass 31500000 video_pll_out 31500000 disp_pixel 31500000 disp_pixel_clk 31500000 Variance = 0 Hz All other clocks rates and parent were the same.

2023-06-12mlxsw: spectrum_router: Reuse work neighbor initialization in work schedulerPetr Machata
After the struct mlxsw_sp_netevent_work.n field initialization is moved here, the body of code that handles NETEVENT_NEIGH_UPDATE is almost identical to the one in the helper function. Therefore defer to the helper instead of inlining the equivalent. Note that previously, the code took and put a reference of the netdevice. The new code defers to mlxsw_sp_dev_lower_is_port() to obviate the need for taking the reference.

2023-06-12mlxsw: spectrum_router: Use the available router pointer for netevent handlingPetr Machata
This code handles NETEVENT_DELAY_PROBE_TIME_UPDATE, which is invoked every time the delay_probe_time changes. mlxsw router currently only maintains one timer, so the last delay_probe_time set wins. Currently, mlxsw uses mlxsw_sp_port_lower_dev_hold() to find a reference to the router. This is no longer necessary. But as a side effect, this makes sure that only updates to "interesting netdevices" (ones that have a physical netdevice lower) are projected. Retain that side effect by calling mlxsw_sp_port_dev_lower_find_rcu() and punting if there is none. Then just proceed using the router pointer that's already at hand in the helper. Note that previously, the code took and put a reference of the netdevice. Because the mlxsw_sp pointer is now obtained from the notifier block, the port pointer (non-) NULL-ness is all that's relevant, and the reference does not need to be taken anymore.

2023-06-12net: enetc: reset taprio stats when taprio is deletedVladimir Oltean
Currently, the window_drop stats persist even if an incorrect Qdisc was removed from the interface and a new one is installed. This is because the enetc driver keeps the state, and that is persistent across multiple Qdiscs. To resolve the issue, clear all win_drop counters from all TX queues when the currently active Qdisc is removed. These counters are zero by default. The counters visible in ethtool -S are also affected, but I don't care very much about preserving those enough to keep them monotonically incrementing.

2023-06-12net/sched: taprio: report class offload stats per TXQ, not per TCVladimir Oltean
The taprio Qdisc creates child classes per netdev TX queue, but taprio_dump_class_stats() currently reports offload statistics per traffic class. Traffic classes are groups of TXQs sharing the same dequeue priority, so this is incorrect and we shouldn't be bundling up the TXQ stats when reporting them, as we currently do in enetc. Modify the API from taprio to drivers such that they report TXQ offload stats and not TC offload stats. There is no change in the UAPI or in the global Qdisc stats.

2023-06-12ipvlan: fix bound dev checking for IPv6 l3s modeHangbin Liu
The commit 59a0b022aa24 ("ipvlan: Make skb->skb_iif track skb->dev for l3s mode") fixed ipvlan bonded dev checking by updating skb skb_iif. This fix works for IPv4, as in raw_v4_input() the dif is from inet_iif(skb), which is skb->skb_iif when there is no route. But for IPv6, the fix is not enough, because in ipv6_raw_deliver() -> raw_v6_match(), the dif is inet6_iif(skb), which is returns IP6CB(skb)->iif instead of skb->skb_iif if it's not a l3_slave. To fix the IPv6 part issue. Let's set IP6CB(skb)->iif to correct ifindex. BTW, ipvlan handles NS/NA specifically. Since it works fine, I will not reset IP6CB(skb)->iif when addr->atype is IPVL_ICMPV6.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== ice: Improve miscellaneous interrupt code Jacob Keller says: This series improves the driver's use of the threaded IRQ and the communication between ice_misc_intr() and the ice_misc_intr_thread_fn() which was previously introduced by commit 1229b33973c7 ("ice: Add low latency Tx timestamp read"). First, a new custom enumerated return value is used instead of a boolean for ice_ptp_process_ts(). This significantly reduces the cognitive burden when reviewing the logic for this function, as the expected action is clear from the return value name. Second, the unconditional loop in ice_misc_intr_thread_fn() is removed, replacing it with a write to the Other Interrupt Cause register. This causes the MAC to trigger the Tx timestamp interrupt again. This makes it possible to safely use the ice_misc_intr_thread_fn() to handle other tasks beyond just the Tx timestamps. It is also easier to reason about since the thread function will exit cleanly if we do something like disable the interrupt and call synchronize_irq(). Third, refactor the handling for external timestamp events to use the miscellaneous thread function. This resolves an issue with the external time stamps getting blocked while processing the periodic work function task. Fourth, a simplification of the ice_misc_intr() function to always return IRQ_WAKE_THREAD, and schedule the ice service task in the ice_misc_intr_thread_fn() instead. Finally, the Other Interrupt Cause is kept disabled over the thread function processing, rather than immediately re-enabled. Special thanks to Michal Schmidt for the careful review of the series and pointing out my misunderstandings of the kernel IRQ code. It has been determined that the race outlined as being fixed in previous series was actually introduced by this series itself, which I've since corrected. ==================== Signed-off-by: David S.

Adds runtime pm support for 7560. As part of probe procedure auto suspend is enabled and auto suspend delay is set to 5000 ms for runtime pm use. Later auto flag is set to power manage the device at run time. On successful communication establishment between host and device the device usage counter is dropped and request to put the device into sleep state (suspend). In TX path, the device usage counter is raised and device is moved out of sleep(resume) for data transmission. In RX path, if the device has some data to be sent it request host platform to change the power state by giving PCI PME message.
