2022-07-08OPP: Migrate set-supported-hw API to use set-config helpersViresh Kumar4-86/+36
Now that we have a central API to handle all OPP table configurations, migrate the set-supported-hw family of helpers to use the new infrastructure. The return type and parameter to the APIs change a bit due to this, update the current users as well in the same commit in order to avoid breaking builds.

The OPP core already have few configuration specific APIs and it is getting complex or messy for both the OPP core and its users. Lets introduce a new set of API which will be used for all kind of different configurations, and shall eventually be used by all the existing ones. The new API, returns a unique token instead of a pointer to the OPP table, which allows the OPP core to drop the resources selectively later on.

2022-07-07net: ocelot: fix wrong time_after usagePavel Skripkin1-9/+8
Accidentally noticed, that this driver is the only user of while (time_after(jiffies...)). It looks like typo, because likely this while loop will finish after 1st iteration, because time_after() returns true when 1st argument _is after_ 2nd one. There is one possible problem with this poll loop: the scheduler could put the thread to sleep, and it does not get woken up for OCELOT_FDMA_CH_SAFE_TIMEOUT_US. During that time, the hardware has done its thing, but you exit the while loop and return -ETIMEDOUT.

2022-07-07net: ethernet: ti: am65-cpsw: Fix devlink port register sequenceSiddharth Vadapalli1-7/+10
Renaming interfaces using udevd depends on the interface being registered before its netdev is registered. Otherwise, udevd reads an empty phys_port_name value, resulting in the interface not being renamed. Fix this by registering the interface before registering its netdev by invoking am65_cpsw_nuss_register_devlink() before invoking register_netdev() for the interface. Move the function call to devlink_port_type_eth_set(), invoking it after register_netdev() is invoked, to ensure that netlink notification for the port state change is generated after the netdev is completely initialized.

2022-07-07net: stmmac: dwc-qos: Disable split header for Tegra194Jon Hunter1-0/+1
There is a long-standing issue with the Synopsys DWC Ethernet driver for Tegra194 where random system crashes have been observed [0]. The problem occurs when the split header feature is enabled in the stmmac driver. In the bad case, a larger than expected buffer length is received and causes the calculation of the total buffer length to overflow. This results in a very large buffer length that causes the kernel to crash. Why this larger buffer length is received is not clear, however, the feedback from the NVIDIA design team is that the split header feature is not supported for Tegra194. Therefore, disable split header support for Tegra194 to prevent these random crashes from occurring.

2022-07-07scsi: lpfc: Revert RSCN_MEMENTO workaround for misbehaved configurationJames Smart3-9/+3
The RSCN_MEMENTO logic was to workaround a target that does not register both FCP and NVMe FC4 types at the same time. This caused the configuration to not produce a second RSCN for the NVMe FC4 type registration in a timely manner. The intention of the RSCN_MEMENTO flag was to always signal to try NVMe PRLI. However, there are other FCP-only target arrays in correctly behaved configurations that reject the NVMe PRLI followed by a LOGO leading to never rediscovering the target after an issue_lip (as LOGO causes a repeat of PLOGI/PRLIs). Revert the RSCN_MEMENTO patch as it is causing correctly behaved configs to fail while it exists only to succeed on a misbehaved config.

When this occurs, the driver "swaps" the ndlp and new_ndlp node parameters to restore WWPN/DID uniqueness in the fc_nodes list per vport. However, the driver neglected to swap the nlp_fc4_type in the ndlp passed to lpfc_plogi_confirm_nport causing a failure to recover the NVMe PLOGI/PRLI and ultimately the NVMe paths.

2022-07-07scsi: sd: Rework asynchronous resume supportBart Van Assche2-18/+71
For some technologies, e.g. an ATA bus, resuming can take multiple seconds. Waiting for resume to finish can cause a very noticeable delay. Hence this commit that restores the behavior from before "scsi: core: pm: Rely on the device driver core for async power management" for most SCSI devices. This commit introduces a behavior change: if the START command fails, do not consider this as a SCSI disk resume failure.
