2021-11-05dt-bindings: mfd: Add Broadcom's MISC blockRafał Miłecki
Broadcom's MISC is an MFD hardware block used on some of their SoCs like bcm63xx and bcm4908. At this point only PCIe reset is fully understood and documented. More functions may be added later.

2021-11-05PCI: Add ACS quirk for Pericom PI7C9X2G switchesNathan Rossi
The Pericom PI7C9X2G404/PI7C9X2G304/PI7C9X2G303 PCIe switches have an erratum for ACS P2P Request Redirect behaviour when used in the cut-through forwarding mode. The recommended work around for this issue is to use the switch in store and forward mode. The erratum results in packets being queued and not being delivered upstream, which can be observed as very poor downstream device performance and/or dropped device-generated data/interrupts. Add a fixup so that when enabling or resuming the downstream port we check if it has enabled ACS P2P Request Redirect, and if so, change the device (via the upstream port) to use the store and forward operating mode.

2021-11-05net: udp: correct the document for udp_memMenglong Dong
udp_mem is a vector of 3 INTEGERs, which is used to limit the number of pages allowed for queueing by all UDP sockets. However, sk_has_memory_pressure() in __sk_mem_raise_allocated() always return false for udp, as memory pressure is not supported by udp, which means that __sk_mem_raise_allocated() will fail once pages allocated for udp socket exceeds udp_mem[0]. Therefor, udp_mem[0] is the only one that limit the number of pages. However, the document of udp_mem just express that udp_mem[2] is the limitation. So, just fix it.

2021-11-04net: phy: fix duplex out of sync problem while changing settingsHeiner Kallweit
As reported by Zhang there's a small issue if in forced mode the duplex mode changes with the link staying up [0]. In this case the MAC isn't notified about the change. The proposed patch relies on the phylib state machine and ignores the fact that there are drivers that uses phylib but not the phylib state machine. So let's don't change the behavior for such drivers and fix it w/o re-adding state PHY_FORCING for the case that phylib state machine is used.

2021-11-04SUNRPC: Check if the xprt is connected before handling sysfs readsAnna Schumaker
xprts don't immediately reconnect when changing the "dstaddr" property, instead this gets handled the next time an operation uses the transport. This could lead to NULL pointer dereferences when trying to read sysfs files between the disconnect and reconnect operations. Fix this by returning an error if the xprt is not connected.

2021-11-04PCI: apple: Configure RID to SID mapper on device additionMarc Zyngier
The Apple PCIe controller doesn't directly feed the endpoint's Requester ID to the IOMMU (DART), but instead maps RIDs onto Stream IDs (SIDs). The DART and the PCIe controller must thus agree on the SIDs that are used for translation (by using the 'iommu-map' property). For this purpose, parse the 'iommu-map' property each time a device gets added, and use the resulting translation to configure the PCIe RID-to-SID mapper. Similarly, remove the translation if/when the device gets removed. This is all driven from a bus notifier which gets registered at probe time. Hopefully this is the only PCI controller driver in the whole system.

2021-11-04iommu/dart: Exclude MSI doorbell from PCIe device IOVA rangeMarc Zyngier
The MSI doorbell on Apple HW can be any address in the low 4GB range. However, the MSI write is matched by the PCIe block before hitting the iommu. It must thus be excluded from the IOVA range that is assigned to any PCIe device.
