2023-03-21PCI: dwc: Fix PORT_LINK_CONTROL update when CDM check enabledYoshihiro Shimoda
If CDM_CHECK is enabled (by the DT "snps,enable-cdm-check" property), 'val' is overwritten by PCIE_PL_CHK_REG_CONTROL_STATUS initialization. Commit ec7b952f453c ("PCI: dwc: Always enable CDM check if "snps,enable-cdm-check" exists") did not account for further usage of 'val', so we wrote improper values to PCIE_PORT_LINK_CONTROL when the CDM check is enabled. Move the PCIE_PORT_LINK_CONTROL update to be completely after the PCIE_PL_CHK_REG_CONTROL_STATUS register initialization.

Disabling the cache in commit 2ff4ba9e3702 ("clk: rs9: Fix I2C accessors") without removing cache synchronization in resume path results in a kernel panic as map->cache_ops is unset, due to REGCACHE_NONE. Enable flat cache again to support resume again. num_reg_defaults_raw is necessary to read the cache defaults from hardware.

2023-03-21ice: remove filters only if VSI is deletedMichal Swiatkowski
Filters shouldn't be removed in VSI rebuild path. Removing them on PF VSI results in no rule for PF MAC after changing for example queues amount. Remove all filters only in the VSI remove flow. As unload should also cause the filter to be removed introduce, a new function ice_stop_eth(). It will unroll ice_start_eth(), so remove filters and close VSI.

2023-03-21ice: fix rx buffers handling for flow director packetsPiotr Raczynski
Adding flow director filters stopped working correctly after commit 2fba7dc5157b ("ice: Add support for XDP multi-buffer on Rx side"). As a result, only first flow director filter can be added, adding next filter leads to NULL pointer dereference attached below. Rx buffer handling and reallocation logic has been optimized, however flow director specific traffic was not accounted for. As a result driver handled those packets incorrectly since new logic was based on ice_rx_ring::first_desc which was not set in this case. Fix this by setting struct ice_rx_ring::first_desc to next_to_clean for flow director received packets.

2023-03-21coresight: etm4x: Do not access TRCIDR1 for identificationSuzuki K Poulose
CoreSight ETM4x architecture clearly provides ways to identify a device via registers in the "Management" class, TRCDEVARCH and TRCDEVTYPE. These registers can be accessed without the Trace domain being powered on. We additionally added TRCIDR1 as fallback in order to cover for any ETMs that may not have implemented TRCDEVARCH. So far, nobody has reported hitting a WARNING we placed to catch such systems. Also, more importantly it is problematic to access TRCIDR1, which is a "Trace" register via MMIO access, without clearing the OSLK. But we cannot mess with the OSLK until we know for sure that this is an ETMv4 device. Thus, this kind of creates a chicken and egg problem unnecessarily for systems "which are compliant" to the ETMv4 architecture. Let us remove the TRCIDR1 fall back check and rely only on TRCDEVARCH.

2023-03-20drm/i915: Update vblank timestamping stuff on seamless M/N changeVille Syrjälä
When we change the M/N values seamlessly during a fastset we should also update the vblank timestamping stuff to make sure the vblank timestamp corrections/guesstimations come out exact. Note that only crtc_clock and framedur_ns can actually end up changing here during fastsets. Everything else we touch can only change during full modesets. Technically we should try to do this exactly at the start of vblank, but that would require some kind of double buffering scheme. Let's skip that for now and just update things right after the commit has been submitted to the hardware. This means the information will be properly up to date when the vblank irq handler goes to work. Only if someone ends up querying some vblanky stuff in between the commit and start of vblank may we see a slight discrepancy. Also this same problem really exists for the DRRS downclocking stuff. But as that is supposed to be more or less transparent to the user, and it only drops to low gear after a long delay (1 sec currently) we probably don't have to worry about it. Any time something is actively submitting updates DRRS will remain in high gear and so the timestamping constants will match the hardware state.

When interrupt auto clear is programmed, any read to the interrupt status register will clear all interrupts. If two interrupts have come in before one can be serviced then this will cause lost interrupts. On AMD USB4 routers this has manifested in odd problems particularly with long strings of control tranfers such as reading the DROM via bit banging. Instead of clearing interrupts automatically, clear the bit corresponding to the given ring's interrupt in the ISR.
