Since overrun interrupt support has been added, there's a regression when
two ADCs are used at the same time, with:
- an ADC configured to use IRQs. EOCIE bit is set. The handler is normally
called in this case.
- an ADC configured to use DMA. EOCIE bit isn't set. EOC triggers the DMA
request. It's then automatically cleared by DMA read. But the handler
gets called due to status bit is temporarily set (IRQ triggered by the
other ADC).
This is a regression as similar issue had been fixed earlier by
commit dcb1092017 ("iio: adc: stm32-adc:
fix a race when using several adcs with dma and irq").
Issue is that stm32_adc_eoc_enabled() returns non-zero value (always)
since OVR bit has been added and enabled for both DMA and IRQ case.
Remove OVR mask in IER register, and rely only on CSR status for overrun.
To avoid subsequent calls to interrupt routine on overrun, CSR OVR bit has
to be cleared. CSR OVR bit cannot be cleared directly by software.
To do this ADC must be stopped first, and OVR bit in ADC ISR has
to be cleared.
Also add a check in ADC IRQ handler to report spurious IRQs.

The DMA (BCDMA/PKTDMA and their rings/flows) events are under the INTA's
supervision as unmapped events in AM64.

the dev_id with it's own when a request comes for BCDMA or PKTDMA
resources.

Enhance validation to support for reject from inet ingress chains.
Note that, reject from inet ingress and netdev ingress differ.
Reject packets from inet ingress are sent through ip_local_out() since
inet reject emulates the IP layer receive path. So the reject packet
follows to classic IP output and postrouting paths.
The reject action from netdev ingress assumes the packet not yet entered
the IP layer, so the reject packet is sent through dev_queue_xmit().
Therefore, reject packets from netdev ingress do not follow the classic
IP output and postrouting paths.

The extra 0 only adds one point in the userspace visible range,
so this change is almost a noop with the current driver behavior.
We don't need the 0% point, userspace seems to handle this just fine
because it uses the bl_power property to turn off the display.
Furthermore after adding "backlight: pwm_bl: Fix interpolation" patch,
the backlight interpolation will work a little differently. So we need
to preemptively remove the 0-3 segment since otherwise we would have a
252 long interpolation that would slowly go between 0 and 3, looking
really bad in userspace. So it's almost a noop/cleanup now, but it will
be required in the future.

In my test setup, I had a SAMA5D27 device configured with ip forwarding, and
second device with usb ethernet (r8152) sending ICMP packets. If the packet
was larger than about 220 bytes, the SAMA5 device would "oops" with the
following trace:

The solution was to force nonlinear buffers to be cloned. This was previously
reported by Klaus Doth (https://www.spinics.net/lists/netdev/msg556937.html)
but never formally submitted as a patch.
This is the third revision, hopefully the formatting is correct this time!

tp->dirty_tx isn't changed outside rtl_tx(). Therefore I see no need
to guarantee a specific order of reading tp->dirty_tx and tp->cur_tx.
Having said that we can remove the memory barrier.
In addition use READ_ONCE() when reading tp->cur_tx because it can
change in parallel to rtl_tx().

This patch adds support for 10GBASE-R interface to the linux driver for
Cadence's ethernet controller.
This controller has separate MAC's and PCS'es for low and high speed paths.
High speed PCS supports 100M, 1G, 2.5G, 5G and 10G through rate adaptation
implementation. However, since it doesn't support auto negotiation, linux
driver is modified to support 10GBASE-R instead of USXGMII.

To allow better problem diagnosis the return codes for SMC-Dv2 are
improved by this patch. A few more CLC DECLINE codes are defined and
sent to the peer when an SMC connection cannot be established.
There are now multiple SMC variations that are offered by the client and
the server may encounter problems to initialize all of them.
Because only one diagnosis code can be sent to the client the decision
was made to send the first code that was encountered. Because the server
tries the variations in the order of importance (SMC-Dv2, SMC-D, SMC-R)
this makes sure that the diagnosis code of the most important variation
is sent.
v2: initialize rc in smc_listen_v2_check().

====================
Support for OcteonTx2 98xx silicon
OcteonTx2 series of silicons have multiple variants, the
98xx variant has two network interface controllers (NIX blocks)
each of which supports upto 100Gbps. Similarly 98xx supports
two crypto blocks (CPT) to double the crypto performance.
The current RVU drivers support a single NIX and
CPT blocks, this patchset adds support for multiple
blocks of same type to be active at the same time.
Also the number of serdes controllers (CGX) have increased
from three to five on 98xx. Each of the CGX block supports
upto 4 physical interfaces depending on the serdes mode ie
upto 20 physical interfaces. At a time each CGX block can
be mapped to a single NIX. The HW configuration to map CGX
and NIX blocks is done by firmware.
NPC has two new interfaces added NIX1_RX and NIX1_TX
similar to NIX0 interfaces. Also MCAM entries is increased
from 4k to 16k. To support the 16k entries extended set
is added in hardware which are at completely different
register offsets. Fortunately new constant registers
can be read to figure out the extended set is present
or not.
This patch set modifies existing AF and PF drivers
in below order to support 98xx:
- Prepare for supporting multiple blocks of same type.
Functions which operate with block type to get or set
resources count are modified to operate with block address
- Manage allocating and freeing LFs from new NIX1 and CPT1 RVU blocks.
- NIX block specific initialization and teardown for NIX1
- Based on the mapping set by Firmware, assign the NIX block
LFs to a PF/VF.
- Multicast entries context is setup for NIX1 along with NIX0
- NPC changes to support extended set of MCAM entries, counters
and NIX1 interfaces to NPC.
- All the mailbox changes required for the new blocks in 98xx.
- Since there are more CGX links in 98xx the hardcoded LBK
link value needed by netdev drivers is not sufficient any
more. Hence AF consumers need to get the number of all links
and calculate the LBK link.
- Debugfs changes to display NIX1 contexts similar to NIX0
- Debugfs change to display mapping between CGX, NIX and PF.

Unlike earlier silicon variants, OcteonTx2 98xx
silicon has 2 NIX blocks and each of the CGX is
mapped to either of the NIX blocks. Each NIX
block supports 100G. Mapping btw NIX blocks and
CGX is done by firmware based on CGX speed config
to have a maximum possible network bandwidth.
Since the mapping is not fixed, it's difficult
for a user to figure out. Hence added a debugfs
entry which displays mapping between CGX LMAC,
NIX block and RVU PF.

This patch puts together all mailbox changes
for 98xx silicon:
Attach ->
Modify resource attach mailbox handler to
request LFs from a block address out of multiple
blocks of same type. If a PF/VF need LFs from two
blocks of same type then attach mbox should be
called twice.
Example:
struct rsrc_attach *attach;
.. Allocate memory for message ..
attach->cptlfs = 3; /* 3 LFs from CPT0 */
.. Send message ..
.. Allocate memory for message ..
attach->modify = 1;
attach->cpt_blkaddr = BLKADDR_CPT1;
attach->cptlfs = 2; /* 2 LFs from CPT1 */
.. Send message ..
Detach ->
Update detach mailbox and its handler to detach
resources from CPT1 and NIX1 blocks.
MSIX ->
Updated the MSIX mailbox and its handler to return
MSIX offsets for the new block CPT1.
Free resources ->
Update free_rsrc mailbox and its handler to return
the free resources count of new blocks NIX1 and CPT1
Links ->
Number of CGX,LBK and SDP links may vary between
platforms. For example, in 98xx number of CGX and LBK
links are more than 96xx. Hence the info about number
of links present in hardware is useful for consumers to
request link configuration properly. This patch sends
this info in nix_lf_alloc_rsp.

On 98xx silicon, NPC block has additional
mcam entries, counters and NIX1 interfaces.
Extended set of registers are present for the
new mcam entries and counters.
This patch does the following:
- updates the register accessing macros
to use extended set if present.
- configures the MKEX profile for NIX1 interfaces also.
- updates mcam entry write functions to use assigned
