2022-09-24Input: synaptics - disable Intertouch for Lenovo T14 and P14s AMD G1Mark Pearson
Since intertouch was enabled for the T14 and P14s AMD G1 laptops there have been a number of reports of touchpads not working well. Debugging this with Synaptics they noted that intertouch should not be enabled as SMBUS host notify is not available on these laptops. Reverting the previous commit (e4ce4d3a939d97bea045eafa13ad1195695f91ce) to restore functionality back to what it was. Note - we are working with Synaptics to see if there is a better solution, but nothing is confirmed as yet.

2022-09-24Input: iqs62x-keys - drop unused device node referencesJeff LaBundy
Each call to device/fwnode_get_named_child_node() must be matched with a call to fwnode_handle_put() once the corresponding node is no longer in use. This ensures a reference count remains balanced in the case of dynamic device tree support. Currently, the driver never calls fwnode_handle_put(). This patch adds the missing calls.

2022-09-24Merge branch 'for-6.0/dax' into libnvdimm-fixesDan Williams
Pick up another "Soft Reservation" fix for v6.0-final on top of some straggling nvdimm fixes that missed v5.19.
2022-09-24devdax: Fix soft-reservation memory descriptionDan Williams
The "hmem" platform-devices that are created to represent the platform-advertised "Soft Reserved" memory ranges end up inserting a resource that causes the iomem_resource tree to look like this: 340000000-43fffffff : hmem.0 340000000-43fffffff : Soft Reserved 340000000-43fffffff : dax0.0 This is because insert_resource() reparents ranges when they completely intersect an existing range. This matters because code that uses region_intersects() to scan for a given IORES_DESC will only check that top-level 'hmem.0' resource and not the 'Soft Reserved' descendant. So, to support EINJ (via einj_error_inject()) to inject errors into memory hosted by a dax-device, be sure to describe the memory as IORES_DESC_SOFT_RESERVED. This is a follow-on to: commit b13a3e5fd40b ("ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP") ...that fixed EINJ support for "Soft Reserved" ranges in the first instance.

2022-09-24PM: runtime: Return -EINPROGRESS from rpm_resume() in the RPM_NOWAIT caseRafael J. Wysocki
The prospective callers of rpm_resume() passing RPM_NOWAIT to it may be confused when it returns 0 without actually resuming the device which may happen if the device is suspending at the given time and it will only resume when the suspend in progress has completed. To avoid that confusion, return -EINPROGRESS from rpm_resume() in that case.

2022-09-24ACPI: CPPC: Disable FIE if registers in PCC regionsJeremy Linton
PCC regions utilize a mailbox to set/retrieve register values used by the CPPC code. This is fine as long as the operations are infrequent. With the FIE code enabled though the overhead can range from 2-11% of system CPU overhead (ex: as measured by top) on Arm based machines. So, before enabling FIE assure none of the registers used by cppc_get_perf_ctrs() are in the PCC region. Finally, add a module parameter which can override the PCC region detection at boot or module reload.

2022-09-24ACPI: scan: Support multiple DMA windows with different offsetsJianmin Lv
In DT systems configurations, of_dma_get_range() returns struct bus_dma_region DMA regions; they are used to set-up devices DMA windows with different offset available for translation between DMA address and CPU address. In ACPI systems configuration, acpi_dma_get_range() does not return DMA regions yet and that precludes setting up the dev->dma_range_map pointer and therefore DMA regions with multiple offsets. Update acpi_dma_get_range() to return struct bus_dma_region DMA regions like of_dma_get_range() does. After updating acpi_dma_get_range(), acpi_arch_dma_setup() is changed for ARM64, where the original dma_addr and size are removed as these arguments are now redundant, and pass 0 and U64_MAX for dma_base and size of arch_setup_dma_ops; this is a simplification consistent with what other ACPI architectures also pass to iommu_setup_dma_ops().

The cause of this error has been investigated and we found that this is related to the WiFi Fast Transaction feature. We observed that this is triggered when the router tells the device to change band. In this case the device first auth to the other band and then the disconnect path from the prev band is triggered. This is problematic with the current rhash implementation since the addrs is used as key and the logic of "adding first, delete later" conflicts with the rhash logic. In fact peer addition will fail since the peer is already added and with that fixed a peer deletion will cause unitended effect by removing the peer just added. Current solution to this is to add additional logic to the peer delete, make sure we are deleting the correct peer taken from the rhash table (and fallback to the peer list) and for the peer add logic delete the peer entry for the rhash list before adding the new one (counting as an error only when a peer with the same vlan_id is asked to be added). With this change, a sta can correctly transition from 2.4GHz and 5GHZ with no drop and no error are printed.

2022-09-24wifi: rtw89: send OFDM rate only in P2P modeDian-Syuan Yang
Check IEEE80211_TX_CTL_NO_CCK_RATE flag to avoid sending frames with CCK rates in 2GHz band. In TX flow, add IEEE80211_TX_CTL_NO_CCK_RATE flag to check and get its lowest rate without CCK rates if the TX type is mgmt frames or data frames. Besides, the decision of phy rate and retry rate in P2P mode are also be handled. In P2P GO mode, it should send beacon of no CCK rates in its frame rate. Therefore, We add a condition to decide which rate is added to beacon content. Moreover, we avoid setting a mask of rates to be used for rate control selection before and after connection in P2P mode.
