Here is the big set of char/misc and a number of other driver subsystem
updates for 6.9-rc1. Included in here are:
- IIO driver updates, loads of new ones and evolution of existing ones
- coresight driver updates
- const cleanups for many driver subsystems
- speakup driver additions
- platform remove callback void cleanups
- mei driver updates
- mhi driver updates
- cdx driver updates for MSI interrupt handling
- nvmem driver updates
- other smaller driver updates and cleanups, full details in the
shortlog
All of these have been in linux-next for a long time with no reported
issue, other than a build warning with some older versions of gcc for a
speakup driver, fix for that will come in a few days when I catch up
with my pending patch queues.

Use the UIO_MEM_DMA_COHERENT type to properly handle mmap for
dma_alloc_coherent buffers.
The cnic l2_ring and l2_buf mmaps have caused page refcount issues as
the dma_alloc_coherent no longer provide __GFP_COMP allocation as per
commit "dma-mapping: reject __GFP_COMP in dma_alloc_attrs".
Fix this by having the uio device use dma_mmap_coherent.
The bnx2 and bnx2x status block allocations are also dma_alloc_coherent,
and should use dma_mmap_coherent. They don't allocate multiple pages,
but this interface does not work correctly with an iommu enabled unless
dma_mmap_coherent is used.

new method is supported by the firmware. Even though this VNIC is
only used for ntuple filters with direct ring destinations, we still
setup the RSS hash to be identical to the default VNIC so that each
RX packet will have the correct hash in the RX completion. This
VNIC is always at VNIC index BNXT_VNIC_NTUPLE.

On newer chips that support the ring table index method for
ntuple filters, the current scheme of using the same VNIC for
both RSS and ntuple filters will not work in all cases. An
ntuple filter can only be directed to a destination ring if
that destination ring is also in the RSS indirection table.
To support ntuple filters with any arbitratry RSS indirection
table that may only include a subset of the rings, we need to
use a separate VNIC for ntuple filters.
This patch provisions the additional VNIC. The next patch will
allocate additional VNIC from firmware and set it up.

1) Drop action for TCP/UDP is supported via flow type
tcp4/udp4/tcp6/udp6.
2) Drop action for ICMPV4/ICMPV6/wildcard is supported
via flow type ipv4/ipv6.

Enable flow type ipv4/ipv6
1) for protocols ICMPV4 and ICMPV6.
2) for wildcard match. Wildcard matches to TCP/UDP/ICMP.
Note that, IPPROTO_RAW(255) i.e. a reserved protocol
considered for a wildcard.

Support subfield masking for IP addresses and ports. Previously, only
entire fields could be included or excluded in NTUPLE filters.

Add ETHTOOL_SRXCLSRLINS and ETHTOOL_SRXCLSRLDEL support for inserting
and deleting L2 ether filter rules. Destination MAC address and
optional VLAN are supported for each filter entry. This is currently
only supported on older BCM573XX and BCM574XX chips only.

While individual filter structures are allocated as needed, there is an
array to keep track of the software filter IDs that we allocate ahead
of time. Rather than relying on a fixed maximum filter count to
allocate this array, get the maximum from the firmware when available.
Move these filter related maximum counts queried from the firmware to the
bnxt_hw_resc struct. If the firmware is not providing these maximum
counts, fall back to the hard-coded constant.

Convert EEE handling to use linkmode bitmaps. This prepares for removing
the legacy bitmaps from struct ethtool_keee. No functional change
intended. When replacing _bnxt_fw_to_ethtool_adv_spds() with
_bnxt_fw_to_linkmode(), remove the fw_pause argument because it's
always passed as 0.
Note:
There's a discussion on whether the underlying implementation is correct,
but it's independent of this mechanical conversion w/o functional change.

bcmasp_get_eee() sets edata->eee_active and edata->eee_enabled from
its own copy, and then calls phy_ethtool_get_eee() which in turn will
call genphy_c45_ethtool_get_eee().
genphy_c45_ethtool_get_eee() will overwrite eee_enabled and eee_active
with its own interpretation from the PHYs settings and negotiation
result.
Therefore, setting these members in bcmasp_get_eee() is redundant, and
can be removed. This also makes intf->eee.eee_active unnecessary, so
remove this and use a local variable where appropriate.
