2023-08-09mmc: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-08-09mmc: mmci: Improve ux500 debug printsLinus Walleij
To conclude the ux500 busy timeout fixes, this improves the debug and error prints so we can see a bit what is going on.

So busy signalling is missed in various ways for various reasons, sometimes it appears that IRQs are simply lost. One hypothesis is that this happens because the events happen so fast that they are transient, and since the MMCI state machine in effect is handling an edge trigger (rising or falling signal on DAT0) the internal logic will miss the event, because the state machine in the hardware is sampling the line, and will at times detect only the first event but miss the second, fireing only one IRQ. We print the second timeout error with dev_err() since it is pretty serious, the other events are so common and simple to handle that we can keep them at dev_dbg() level.

This change handles the first part. We refactor the common code in enetc_psi_create() and enetc_psi_destroy(), and use the PCI fixup only for those functions for which enetc_pf_probe() won't get called. This avoids some work being done twice for the PFs which are enabled.

2023-08-09PCI: move OF status = "disabled" detection to dev->match_driverVladimir Oltean
The blamed commit has broken probing on arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi when &enetc_port0 (PCI function 0) has status = "disabled". Background: pci_scan_slot() has logic to say that if the function 0 of a device is absent, the entire device is absent and we can skip the other functions entirely. Traditionally, this has meant that pci_bus_read_dev_vendor_id() returns an error code for that function. However, since the blamed commit, there is an extra confounding condition: function 0 of the device exists and has a valid vendor id, but it is disabled in the device tree. In that case, pci_scan_slot() would incorrectly skip the entire device instead of just that function. In the case of NXP LS1028A, status = "disabled" does not mean that the PCI function's config space is not available for reading. It is, but the Ethernet port is just not functionally useful with a particular SerDes protocol configuration (0x9999) due to pinmuxing constraints of the Soc. So, pci_scan_slot() skips all other functions on the ENETC ECAM (enetc_port1, enetc_port2, enetc_mdio_pf3 etc) when just enetc_port0 had to not be probed. There is an additional regression introduced by the change, caused by its fundamental premise. The enetc driver needs to run code for all PCI functions, regardless of whether they're enabled or not in the device tree. That is no longer possible if the driver's probe function is no longer called. But Rob recommends that we move the of_device_is_available() detection to dev->match_driver, and this makes the PCI fixups still run on all functions, while just probing drivers for those functions that are enabled. So, a separate change in the enetc driver will have to move the workarounds to a PCI fixup.

2023-08-09fsi: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-08-08iavf: fix potential races for FDIR filtersPiotr Gardocki
Add fdir_fltr_lock locking in unprotected places. The change in iavf_fdir_is_dup_fltr adds a spinlock around a loop which iterates over all filters and looks for a duplicate. The filter can be removed from list and freed from memory at the same time it's being compared. All other places where filters are deleted are already protected with spinlock. The remaining changes protect adapter->fdir_active_fltr variable so now all its uses are under a spinlock.

Meaning, completion EQs will be created only when needed. Patch #1 introduces a counter for tracking the current number of completion EQs. Patches #2-6 refactor the existing infrastructure of managing completion EQs and completion IRQs to be compatible with per-vector allocation/release requests. Patches #7-8 modify the CPU-to-IRQ affinity calculation to be resilient in case the affinity is requested but completion IRQ is not allocated yet. Patch #9 function rename.
