2020-10-30net: fec: fix MDIO probing for some FEC hardware blocksGreg Ungerer2-13/+22
Some (apparently older) versions of the FEC hardware block do not like the MMFR register being cleared to avoid generation of MII events at initialization time. The action of clearing this register results in no future MII events being generated at all on the problem block. This means the probing of the MDIO bus will find no PHYs. Create a quirk that can be checked at the FECs MII init time so that the right thing is done. The quirk is set as appropriate for the FEC hardware blocks that are known to need this.

2020-10-30drm/i915: Get rid of ibx_irq_pre_postinstall()Ville Syrjälä1-27/+15
ibx_irq_pre_postinstall() looks totally pointless. We can just init both SDEIMR and SDEIER at the same time before enabling the master interrupt. It's equally racy as the other order due to doing all of this from the postinstall stage with the interrupt handler already in place. That is, safe with MSI but racy with shared legacy interrupts. Fortunately we should have MSI on all ilk+.

No reason that I can see why we should enable the hpd detection logic already during irq postinstall phase. We don't even do this on all the platforms. We just need it before we actually enable the hotplug interrupts in .hpd_irq_setup(), and in fact we already do it there as well. Let's just eliminate the redundant early setup.

Also since each encoder is really a combination of the DDI and the PHY we include the PHY name as well. ICL is a bit special since it already has the two different types of DDIs (combo or TC) but it still calls them just DDI A-F regarless of the type. For that let's add an extra "(TC)" note to remind is which type of DDI it really is. The code is darn ugly, but not sure there's much we can do about it.

2020-10-30drm/panfrost: Support cache-coherent integrationsRobin Murphy4-0/+6
When the GPU's ACE-Lite interface is fully wired up and capable of snooping CPU caches, it may be described as "dma-coherent" in devicetree, which will already inform the DMA layer not to perform unnecessary cache maintenance. However, we still need to ensure that the GPU uses the appropriate cacheable outer-shareable attributes in order to generate the requisite snoop signals, and that CPU mappings don't create a mismatch by using a non-cacheable type either.

2020-10-30iommu/io-pgtable-arm: Support coherency for Mali LPAERobin Murphy1-1/+10
Midgard GPUs have ACE-Lite master interfaces which allows systems to integrate them in an I/O-coherent manner. It seems that from the GPU's viewpoint, the rest of the system is its outer shareable domain, and so even when snoop signals are wired up, they are only emitted for outer shareable accesses. As such, setting the TTBR_SHARE_OUTER bit does indeed get coherent pagetable walks working nicely for the coherent T620 in the Arm Juno SoC.

vdpa_sim generates a ramdom MAC address but it is never used by upper layers because the VIRTIO_NET_F_MAC bit is not set in the features list. Because of that, virtio-net always regenerates a random MAC address each time it is loaded whereas the address should only change on vdpa_sim load/unload.

This reverts commit f87812284172a9809820d10143b573d833cd3f75 ("drm/amdgpu: Fix bug where DPM is not enabled after hibernate and resume"). It was intended to fix Hawaii S4(hibernation) issue but break S3. As ixFEATURE_STATUS is filled with garbage data on resume which can be only cleared by reloading smc firmware(but that will involve many changes). So, we will revert this S4 fix and seek a new way.

2020-10-30drm/amd/pm: fix out-of-bound read on pptable->SkuReservedColin Ian King1-1/+0
A recent change added two uint16_t elements to PPTable_t and reduced the uint32_t array down to 8 elements. This results in the dev_info printing of pptable->SkuReserved[8] accessing a value that is out-of-range on array SkuReserved. The array has been shrunk by 1 element, so remove this extraneous dev_info message.
