2024-02-27mmc: core: constify the struct device_type usageRicardo B. Marliere
Since commit aed65af1cc2f ("drivers: make device_type const"), the driver core can properly handle constant struct device_type. Move the sdio_type, sd_type and mmc_type variables to be constant structures as well, placing it into read-only memory which can not be modified at runtime.

2024-02-27platform/mellanox: mlxbf-pmc: Ignore unsupported performance blocksLuiz Capitulino
Currently, the driver has two behaviors to deal with new & unsupported performance blocks reported by the firmware: 1. For register and unknown block types, the driver will fail to load with the following error message: [ 4510.956369] mlxbf-pmc: probe of MLNXBFD2:00 failed with error -22 2. For counter and crspace blocks, the driver will load and sysfs files will be created but getting the contents of event_list or trying to setup the counter will fail Instead, let's ignore and log unsupported blocks. This means the driver will always load and unsupported blocks will never show up in sysfs.

The mlxbf_pmc_event_list() function returns a pointer to an array of supported events and the array size. The array size is returned via a pointer passed as an argument, which is mandatory.

2024-02-27platform/x86: wmi: Always evaluate _WED when receiving an eventArmin Wolf
The ACPI WMI specification states: "The _WED control method is evaluated by the mapper in response to receiving a notification from a control method." This means that _WED should be evaluated unconditionally even if no WMI event consumers are present. Some firmware implementations actually depend on this behavior by storing the event data inside a queue which will fill up if the WMI core stops retrieving event data items due to no consumers being present Fix this by always evaluating _WED even if no WMI event consumers are present.

2024-02-27platform/x86: wmi: Prevent incompatible event driver from probingArmin Wolf
If a WMI event driver has no_notify_data set, then it indicates support for WMI events which provide no notify data, otherwise the notify() callback expects a valid ACPI object as notify data. However if a WMI event driver which requires notify data is bound to a WMI event device which cannot retrieve such data due to the _WED ACPI method being absent, then the driver will be dysfunctional since all WMI events will be dropped due to the missing notify data. Fix this by not allowing such WMI event drivers to bind to WMI event devices which do not support retrieving of notify data. Also reword the description of no_notify_data a bit.

2024-02-27net: stmmac: mmc_core: Drop interrupt registers from statsJesper Nilsson
The MMC IPC interrupt status and interrupt mask registers are of little use as Ethernet statistics, but incrementing counters based on the current interrupt and interrupt mask registers makes them actively misleading. For example, if the interrupt mask is set to 0x08420842, the current code will increment by that amount each iteration, leading to the following sequence of nonsense: mmc_rx_ipc_intr_mask: 969816526 mmc_rx_ipc_intr_mask: 1108361744 These registers have been included in the Ethernet statistics since the first version of MMC back in 2011 (commit 1c901a46d57). That commit also mentions the MMC interrupts as "something to add later (if actually useful)". If the registers are actually useful, they should probably be part of the Ethernet register dump instead of statistics, but for now, drop the counters for mmc_rx_ipc_intr and mmc_rx_ipc_intr_mask completely.

2024-02-27net: ethernet: adi: adin1110: Reduce the MDIO_TRDONE poll intervalCiprian Regus
In order to do a clause 22 access to the PHY registers of the ADIN1110, we have to write the MDIO frame to the ADIN1110_MDIOACC register, and then poll the MDIO_TRDONE bit (for a 1) in the same register. The device will set this bit to 1 once the internal MDIO transaction is done. In practice, this bit takes ~50 - 60 us to be set. The first attempt to poll the bit is right after the ADIN1110_MDIOACC register is written, so it will always be read as 0. The next check will only be done after 10 ms, which will result in the MDIO transactions taking a long time to complete. Reduce this polling interval to 100 us. Since this interval is short enough, switch the poll function to readx_poll_timeout_atomic() instead.

2024-02-27net: ipa: don't bother aborting system resumeAlex Elder
The IPA interrupt can fire if there is data to be delivered to a GSI channel that is suspended. This condition occurs in three scenarios. First, runtime power management automatically suspends the IPA hardware after half a second of inactivity. This has nothing to do with system suspend, so a SYSTEM IPA power flag is used to avoid calling pm_wakeup_dev_event() when runtime suspended. Second, if the system is suspended, the receipt of an IPA interrupt should trigger a system resume. Configuring the IPA interrupt for wakeup accomplishes this. Finally, if system suspend is underway and the IPA interrupt fires, we currently call pm_wakeup_dev_event() to abort the system suspend. The IPA driver correctly handles quiescing the hardware before suspending it, so there's really no need to abort a suspend in progress in the third case. We can simply quiesce and suspend things, and be done. Incoming data can still wake the system after it's suspended. The IPA interrupt has wakeup mode enabled, so if it fires *after* we've suspended, it will trigger a wakeup (if not disabled via sysfs). Stop calling pm_wakeup_dev_event() to abort a system suspend in progress in ipa_power_suspend_handler(). Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
