2023-12-18platform/x86/amd/pmc: Only run IRQ1 firmware version check on CezanneMario Limonciello
amd_pmc_wa_czn_irq1() only runs on Cezanne platforms currently but may be extended to other platforms in the future. Rename the function and only check platform firmware version when it's called for a Cezanne based platform.

2023-12-15Revert "PCI: acpiphp: Reassign resources on bridge if necessary"Bjorn Helgaas
This reverts commit 40613da52b13fb21c5566f10b287e0ca8c12c4e9 and the subsequent fix to it: cc22522fd55e ("PCI: acpiphp: Use pci_assign_unassigned_bridge_resources() only for non-root bus") 40613da52b13 fixed a problem where hot-adding a device with large BARs failed if the bridge windows programmed by firmware were not large enough. cc22522fd55e ("PCI: acpiphp: Use pci_assign_unassigned_bridge_resources() only for non-root bus") fixed a problem with 40613da52b13: an ACPI hot-add of a device on a PCI root bus (common in the virt world) or firmware sending ACPI Bus Check to non-existent Root Ports (e.g., on Dell Inspiron 7352/0W6WV0) caused a NULL pointer dereference and suspend/resume hangs. Unfortunately the combination of 40613da52b13 and cc22522fd55e caused other problems: - Fiona reported that hot-add of SCSI disks in QEMU virtual machine fails sometimes. - Dongli reported a similar problem with hot-add of SCSI disks. - Jonathan reported a console freeze during boot on bare metal due to an error in radeon GPU initialization. Revert both patches to avoid adding these problems. This means we will again see the problems with hot-adding devices with large BARs and the NULL pointer dereferences and suspend/resume issues that 40613da52b13 and cc22522fd55e were intended to fix.

2023-12-15accel/qaic: Implement quirk for SOC_HW_VERSIONJeffrey Hugo
The SOC_HW_VERSION register in the BHI space is not correctly initialized by the device and in many cases contains uninitialized data. The register could contain 0xFFFFFFFF which is a special value to indicate a link error in PCIe, therefore if observed, we could incorrectly think the device is down. Intercept reads for this register, and provide the correct value - every production instance would read 0x60110200 if the device was operating as intended.

2023-12-15usb: fotg210-hcd: delete an incorrect bounds testDan Carpenter
Here "temp" is the number of characters that we have written and "size" is the size of the buffer. The intent was clearly to say that if we have written to the end of the buffer then stop. However, for that to work the comparison should have been done on the original "size" value instead of the "size -= temp" value. Not only will that not trigger when we want to, but there is a small chance that it will trigger incorrectly before we want it to and we break from the loop slightly earlier than intended. This code was recently changed from using snprintf() to scnprintf(). With snprintf() we likely would have continued looping and passed a negative size parameter to snprintf(). This would have triggered an annoying WARN(). Now that we have converted to scnprintf() "size" will never drop below 1 and there is no real need for this test. We could change the condition to "if (temp <= 1) goto done;" but just deleting the test is cleanest.

2023-12-15usb-storage: Add quirk for incorrect WP on Kingston DT Ultimate 3.0 G3Tasos Sahanidis
This flash drive reports write protect during the first mode sense. In the past this was not an issue as the kernel called revalidate twice, thus asking the device for its write protect status twice, with write protect being disabled in the second mode sense. However, since commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to avoid calling revalidate twice") that is no longer the case, thus the device shows up read only.

2023-12-15nvmem: brcm_nvram: store a copy of NVRAM contentRafał Miłecki
This driver uses MMIO access for reading NVRAM from a flash device. Underneath there is a flash controller that reads data and provides mapping window. Using MMIO interface affects controller configuration and may break real controller driver. It was reported by multiple users of devices with NVRAM stored on NAND. Modify driver to read & cache NVRAM content during init and use that copy to provide NVMEM data when requested. On NAND flashes due to their alignment NVRAM partitions can be quite big (1 MiB and more) while actual NVRAM content stays quite small (usually 16 to 32 KiB). To avoid allocating so much memory check for actual data length.

2023-12-15drm/nouveau/kms/nv50-: Don't allow inheritance of headless iorsLyude Paul
Turns out we made a silly mistake when coming up with OR inheritance on nouveau. On pre-DCB 4.1, iors are statically routed to output paths via the DCB. On later generations iors are only routed to an output path if they're actually being used. Unfortunately, it appears with NVIF_OUTP_INHERIT_V0 we make the mistake of assuming the later is true on all generations, which is currently leading us to return bogus ior -> head assignments through nvif, which causes WARN_ON(). So - fix this by verifying that we actually know that there's a head assigned to an ior before allowing it to be inherited through nvif. This -should- hopefully fix the WARN_ON on GT218 reported by Borislav.

2023-12-15drm/nouveau: Fixup gk20a instobj hierarchyThierry Reding
Commit 12c9b05da918 ("drm/nouveau/imem: support allocations not preserved across suspend") uses container_of() to cast from struct nvkm_memory to struct nvkm_instobj, assuming that all instance objects are derived from struct nvkm_instobj. For the gk20a family that's not the case and they are derived from struct nvkm_memory instead. This causes some subtle data corruption (nvkm_instobj.preserve ends up mapping to gk20a_instobj.vaddr) that causes a NULL pointer dereference in gk20a_instobj_acquire_iommu() (and possibly elsewhere) and also prevents suspend/resume from working. Fix this by making struct gk20a_instobj derive from struct nvkm_instobj instead.

2023-12-14spi: atmel: Fix clock issue when using devices with different polaritiesLouis Chauvet
The current Atmel SPI controller driver (v2) behaves incorrectly when using two SPI devices with different clock polarities and GPIO CS. When switching from one device to another, the controller driver first enables the CS and then applies whatever configuration suits the targeted device (typically, the polarities). The side effect of such order is the apparition of a spurious clock edge after enabling the CS when the clock polarity needs to be inverted wrt. the previous configuration of the controller. This parasitic clock edge is problematic when the SPI device uses that edge for internal processing, which is perfectly legitimate given that its CS was asserted. Indeed, devices such as HVS8080 driven by driver gpio-sr in the kernel are shift registers and will process this first clock edge to perform a first register shift. In this case, the first bit gets lost and the whole data block that will later be read by the kernel is all shifted by one. Current behavior: The actual switching of the clock polarity only occurs after the CS when the controller sends the first message: CLK ------------\ /-\ /-\ | | | | | . . . \---/ \-/ \ CS -----\ | \------------------ ^ ^ ^ | | | | | Actual clock of the message sent | | | Change of clock polarity, which occurs with the first | write to the bus. This edge occurs when the CS is | already asserted, and can be interpreted as | the first clock edge by the receiver. | GPIO CS toggle This issue is specific to this controller because while the SPI core performs the operations in the right order, the controller however does not. In practice, the controller only applies the clock configuration right before the first transmission. So this is not a problem when using the controller's dedicated CS, as the controller does things correctly, but it becomes a problem when you need to change the clock polarity and use an external GPIO for the CS. One possible approach to solve this problem is to send a dummy message before actually activating the CS, so that the controller applies the clock polarity beforehand. New behavior: CLK ------\ /-\ /-\ /-\ /-\ | | | ... | | | | ... | | \------/ \- -/ \------/ \- -/ \------ CS -\/-----------------------\ || | \/ \--------------------- ^ ^ ^ ^ ^ | | | | | | | | | Expected clock cycles when | | | | sending the message | | | | | | | Actual GPIO CS activation, occurs inside | | | the driver | | | | | Dummy message, to trigger clock polarity | | reconfiguration. This message is not received and | | processed by the device because CS is low. | | | Change of clock polarity, forced by the dummy message. This | time, the edge is not detected by the receiver. | This small spike in CS activation is due to the fact that the spi-core activates the CS gpio before calling the driver's set_cs callback, which deactivates this gpio again until the clock polarity is correct. To avoid having to systematically send a dummy packet, the driver keeps track of the clock's current polarity. In this way, it only sends the dummy packet when necessary, ensuring that the clock will have the correct polarity when the CS is toggled. There could be two hardware problems with this patch: 1- Maybe the small CS activation peak can confuse SPI devices 2- If on a design, a single wire is used to select two devices depending on its state, the dummy message may disturb them.
