Michal Kalderon 6aebde8dc7 qed: FW 8.42.2.0 Expose new registers and change windows
This patch contains register initialization related changes.
- Modifications to the runtime offsets - these are defines used
  by the driver or firmware functions to set values that are used
  by the initialization functions to set device register values.
- Global window values changes to provide different device register
  ranges.
- Additional device registers addresses were added to the register file,
  used in later stages.

David S. Miller 3d4864b30b Merge branch 'octeontx2-pf-Add-network-driver-for-physical-function'
Sunil Goutham says:

====================
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

Linu Cherian 50fe6c02e5 octeontx2-pf: Register and handle link notifications
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.

Sunil Goutham 3ca6c4c882 octeontx2-pf: Add packet transmission support
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.

Completion queue (CQ) is the one with which HW notifies SW on a packet
reception or transmission. Each of the RQ and SQ are mapped to a unique
CQ and again both CQs are mapped to same interrupt ie the CINT. So that
each core has one interrupt source in whose handler both Rx and Tx
notifications are processed.

Also
- Registered a NAPI handler for the CINT.
- Setup coalescing parameters.
- IRQ affinity hints etc

Sunil Goutham 05fcc9e089 octeontx2-pf: Attach NIX and NPA block LFs
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.

Also adds support to process these messages in both directions
ie responses to PF initiated DOWN (PF => AF) messages and AF
initiated UP messages (AF => PF).

Mbox communication APIs and message formats are defined in AF driver

Leon Romanovsky 6a7e25c7fb net/core: Replace driver version to be kernel version
In order to stop useless driver version bumps and unify output
presented by ethtool -i, let's set default version string.

As Linus said in [1]: "Things are supposed to be backwards and
forwards compatible, because we don't accept breakage in user
space anyway. So versioning is pointless, and only causes
problems."

They cause problems when users start to see version changes
and expect specific set of features which will be different
for stable@, vanilla and distribution kernels.

Distribution kernels are based on some kernel version with extra
patches on top, for example, in RedHat world this "extra" is a lot
and for them your driver version say nothing. Users who run vanilla
kernels won't use driver version information too, because running
such kernels requires knowledge and understanding.

Another set of problems are related to difference in versioning scheme
and such doesn't allow to write meaningful automation which will work
sanely on all ethtool capable devices.

Before this change:
[leonro@erver ~]$ ethtool -i eth0
driver: virtio_net
version: 1.0.0
After this change and once ->version assignment will be deleted
from virtio_net:
[leonro@server ~]$ ethtool -i eth0
driver: virtio_net
version: 5.5.0-rc6+

Florian Fainelli ea0ad0ff38 dt-bindings: thermal: Define BCM7216 thermal sensor compatible
BCM7216 is a 16nm process STB chip, which requires a different
compatible string to differentiate different temperature formulas.

Florian Fainelli 8bcda3257a thermal: brcmstb_thermal: Prepare to support a different process
The driver is currently assuming that it is operating with a 28nm
process chip, which has a specific formula to convert temperature to a
code and vice versa. Update the code to support providing two key
values: offset and multiplier to derive the correct formulas.

Florian Fainelli e1ff6fc22f thermal: brcmstb_thermal: Do not use DT coefficients
At the time the brcmstb_thermal driver and its binding were merged, the
DT binding did not make the coefficients properties a mandatory one,
therefore all users of the brcmstb_thermal driver out there have a non
functional implementation with zero coefficients. Even if these
properties were provided, the formula used for computation is incorrect.

The coefficients are entirely process specific (right now, only 28nm is
supported) and not board or SoC specific, it is therefore appropriate to
hard code them in the driver given the compatibility string we are
probed with which has to be updated whenever a new process is
introduced.

We remove the existing coefficients definition since subsequent patches
are going to add support for a new process and will introduce new
coefficients as well.

Geert Uytterhoeven 263c8c4c76 thermal: rcar_thermal: Use usleep_range() instead of udelay()
rcar_thermal_update_temp() takes a mutex, so it is always called in a
context that can sleep.  Hence replace the 300 µs busy loop by a call to
usleep_range(), to allow other threads to run.
