With the STM32 thermal peripheral, it is not possible to dump the
temperature that has caused the interrupt.
When the temperature reaches the low threshold, we generally read
a temperature that is a little bit higher than the low threshold.
This maybe due to sampling precision, and also because the CPU becomes
hotter when it quits WFI mode.
In that case, the framework does not change the trip points. This leads
to a lot of low threshold interrupts.
The fix is to set the low threshold value 0.5 degrees Celsius
below the actual request.
The problem is not so frequent with the high threshold and it would
no be a good idea to set the threshold value higher than the request.

When devm_thermal_zone_of_sensor_register() is called from
hwmon_thermal_add_sensor() it is possible that the relevant sensor is
missing an OF node. In this case thermal_zone_of_sensor_register() returns
-EINVAL which causes hwmon_thermal_add_sensor() to fail as well. This patch
changes relevant return code of thermal_zone_of_sensor_register() to
-ENODEV, which is tolerated by hwmon_thermal_add_sensor().
Here is a particular case of such behaviour: the Marvell ethernet PHYs
driver registers hwmon device for the built-in temperature sensor (see
drivers/net/phy/marvell.c). Since the sensor doesn't have associated OF
node devm_hwmon_device_register() returns error which ultimately causes
failure of the PHY driver's probe function.

Michal Kalderon says:
====================
qed*: Utilize FW 8.42.2.0
This FW contains several fixes and features, main ones listed below.
We have taken into consideration past comments on previous FW versions
that were uploaded and tried to separate this one to smaller patches to
ease review.
- RoCE
- SRIOV support
- Fixes in following flows:
- latency optimization flow for inline WQEs
- iwarp OOO packed DDPs flow
- tx-dif workaround calculations flow
- XRC-SRQ exceed cache num
- iSCSI
- Fixes:
- iSCSI TCP out-of-order handling.
- iscsi retransmit flow
- Fcoe
- Fixes:
- upload + cleanup flows
- Debug
- Better handling of extracting data during traffic
- ILT Dump -> dumping host memory used by chip
- MDUMP -> collect debug data on system crash and extract after
reboot
Patches prefixed with FW 8.42.2.0 are required to work with binary
8.42.2.0 FW where as the rest are FW related but do not require the
binary.
Changes from V2
---------------
- Move FW version to the start of the series to maintain minimal compatibility
- Fix some kbuild errors:
- frame size larger than 1024 (Queue Manager patch - remove redundant
field from struct)
- sparse warning on endianity (Dmae patch fix - wrong use of __le32 for field
used only on host, should be u32)
- static should be used for some functions (Debug feature ilt and mdump)
Reported-by: kbuild test robot <lkp@intel.com>
Changes from V1
---------------
- Remove epoch + kernel version from device debug dump
- don't bump driver version
====================

Add to debug dump more information on the platform it was collected
from (pci func, path id).
Provide human readable reg fifo erros.
Removed static debug arrays from HSI Functions, and move them to
the hwfn.
Some structures were slightly changed (removing reserved chip id
for example) which lead to many long initializations being modified
with one parameter less during initialization. This leads to
some long diffs that don't really change anything.

The QM phase init tool can be invoked multiple times during
the driver lifetime. Part of the init comes from the runtime array.
The logic for setting the values did not init all values, basically
assuming the runtime array was all zeroes. But if it was invoked
multiple times, nobody was zeroing it after the first time.

LL2 queues were a limited resource due to FW constraints.
This FW introduced a new resource which is a context based ll2 queue
(memory on host). The additional ll2 queues are required for RDMA SRIOV.
The code refers to the previous ll2 queues as ram-based or legacy, and the
new queues as ctx-based.
This change decreased the "legacy" ram-based queues therefore the first ll2
queue used for iWARP was converted to the ctx-based ll2 queue.
This feature also exposed a bug in the DIRECT_REG_WR64 macro implementation
which didn't have an effect in other use cases.

There are several wide-bus registers written to by the fw_funcs
that require using the dmae for atomicity. Therefore using the dmae
channel functionality was added to the fw_funcs file, since the code
is very similar to the previously used code, the structures used were
moved to qed_hsi. Due to FW conventions, the names of the flags in the
struct changed. Since this required slight modification in the places
that set the flags the code was modified to use GET/SET FIELD macros.

octeontx2-pf: Add network driver for physical function
OcteonTX2 SOC's resource virtualization unit (RVU) supports
multiple physical and virtual functions. Each of the PF's
functionality is determined by what kind of resources are attached
to it. If NPA and NIX blocks are attached to a PF it can function
as a highly capable network device.
This patch series add a network driver for the PF. Initial set of
patches adds mailbox communication with admin function (RVU AF)
and configuration of queues. Followed by Rx and tx pkts NAPI
handler and then support for HW offloads like RSS, TSO, Rxhash etc.
Ethtool support to extract stats, config RSS, queue sizes, queue
count is also added.
Added documentation to give a high level overview of HW and
different drivers which will be upstreamed and how they interact.
Changes from v5:
* Fixed otx2_atomic64_add() non ARM64 fallback definition.
- Suggested by David Miller
Changes from v4:
* Replaced pci_set_dma_mask and pci_set_consistent_dma_mask
fn()s with dma_set_mask_and_coherent().
* Some additonal code cleanup.
* Fixed receive buffer segmnetation logic in otx2_alloc_rbuf()
* Removed all unused BIG_ENDIAN structure definitions.
* Removed unnecessary memory barriers
- Sugested by Jakub Kicinski
* Fixed mailbox initalization failure handling
* Removed unused function parameter in otx2_skb_add_frag()
- Suggested by Maciej Fijalkowski
Changes from v3:
* Fixed receive side scaling reinitialization during interface
DOWN and UP to retain user configured settings, if any.
* Removed driver version from ethtool.
* Fixed otx2_set_rss_hash_opts() to return error incase RSS is
not enabled.
- Sugested by Jakub Kicinski
Changes from v2:
* Removed frames, bytes, dropped packet stats from ethtool to avoid
duplication of same stats in netlink and ethtool.
- Sugested by Jakub Kicinski
* Removed number of channels and ringparam upper bound checking
in ethtool support.
* Fixed RSS hash option setting to reject unsupported config.
- Suggested by Michal Kubecek
Changes from v1:
* Made driver dependent on 64bit, to fix build errors related to
non availability of writeq/readq APIs for 32bit platforms.
- Reported by kbuild test robot

PF and AF (admin function) shares 64KB of reserved memory region for
communication. This region is shared for
- Messages sent by PF and responses sent by AF.
- Notifications sent by AF and ACKs sent by PF.
This patch adds infrastructure to handle notifications sent
by AF and adds handlers to process them.
One of the main usecase of notifications from AF is physical
link changes. So this patch adds registration of PF with AF
to receive link status change notifications and also adds
the handler for that notification.

This patch adds the packet transmission support.
For a given skb prepares send queue descriptors (SQEs) and pushes them
to HW. Here driver doesn't maintain it's own SQ rings, SQEs are pushed
to HW using a silicon specific operations called LMTST. From the
instuction HW derives the transmit queue number and queues the SQE to
that queue. These LMTST instructions are designed to avoid queue
maintenance in SW and lockless behavior ie when multiple cores are trying
to add SQEs to same queue then HW will takecare of serialization, no need
for SW to hold locks.
Also supports scatter/gather.

For a PF to function as a NIC, NPA (for Rx buffers, Tx descriptors etc)
and NIX (for rcv, send and completion queues) are the minimum resources
needed. So request admin function (AF) to attach one each of NIX and NPA
block LFs (local functions).
Only AF can configure a LF's contexts, so request AF to allocate memory
for NPA aura/pool and NIX RQ/SQ/CQ HW contexts. Upon receiving response,
save some of the HW constants like number of pointers per stack page,
size of send queue buffer (SQBs, where SQEs are queued by HW) e.t.c which
are later used to initialize queues.
A HW context here is like a state machine maintained for a descriptor
queue. eg size, head/tail pointers, irq etc etc. HW maintains this in
memory.
