The device-tree checking code sees node names "i2c" and "spi" in the
pinctrl definition and thinks these are defining i2c or spi devices,
and complains that they look wrong.
So add a '0' to the end of each name (much like "uart" and "rgmii"
have numbers at the end) to avoid the warning.

Since commit bb276262e88d ("mtd: spi-nor: only apply reset hacks to
broken hardware"), we need to mark the spi-nor as "broken" for reboot
to work.
Note that nothing is actually broken here. The hardware-watchdog in
the SoC isn't wired in a way that works, but then the board doesn't
claim to support a hardware watchdog - and the SPI certain isn't
"broken".
This causes an annoying warning on every boot, but that is better than
failing on ever reboot.

Implement the get_state() function and set the initial state to reflect
real state of the hardware. This allows to keep the PWM running if it was
enabled in bootloader. It is very similar to the GPIO behavior. GPIO pin
set as output in bootloader keep the same setting in Linux unless it is
reconfigured.
If we find the PWM block enabled we need to prepare and enable its source
clock otherwise the clock will be disabled late in the boot as unused.
That will leave the PWM in enabled state but with disabled clock. That has
a side effect that the PWM output is left at its current level at which
the clock was disabled. It is totally non-deterministic and it may be LOW
or HIGH.

I had started the removal of semaphores in this driver without knowing
that Nicolas Saenz Julienne also worked on this. In case of the "remote
event" infrastructure, my solution seemed significantly better, so I'm
proposing this as a change on top.
The problem with using either semaphores or completions here is that
it's an overly complex way of waking up a thread, and it looks like the
'count' of the semaphore can easily get out of sync, even though I found
it hard to come up with a specific example.
Changing it to a 'wait_queue_head_t' instead of a completion simplifies
this by letting us wait directly on the 'event->fired' variable that is
set by the videocore.
Another simplification is passing the wait queue directly into the helper
functions instead of going through the fragile logic of recording the
offset inside of a structure as part of a shared memory variable. This
also avoids one uncached memory read and should be faster.
Note that I'm changing it back to 'killable' after the previous patch
changed 'killable' to 'interruptible', apparently based on a misunderstanding
of the subtle down_interruptible() macro override in vchiq_killable.h.

This driver uses many semaphores, most of them are equivalent to

completions a while ago, so do the same here.
In this usage scenario, the two are equivalent, so the behavior

Changes do_insn*_ioctl functions to allow for data lengths for each
comedi_insn of up to 2^16. This patch also changes these functions to only
allocate as much memory as is necessary for each comedi_insn, rather than
allocating a fixed-sized scratch space.
In testing some user-space code for the new INSN_DEVICE_CONFIG_GET_ROUTES
facility with some newer hardware, I discovered that do_insn_ioctl and
do_insnlist_ioctl limited the amount of data that can be passed into the
kernel for insn's to a length of 256. For some newer hardware, the number
of routes can be greater than 1000. Working around the old limits (256)
would complicate the user-space/kernel interaction.
The new upper limit is reasonable with current memory available and does
not otherwise impact the memory footprint for any current or otherwise
typical configuration.

As explained in previous patch, this SPI controller seems to be
tested on SPI flash only before mass production and some bits are
swizzled under other SPI modes probably due to incorrect wiring
inside the silicon. Drop implementation of SPI mode 1/2/3 since
they are broken.
Also drop RT2880_SPI_MODE_BITS macro because we now have only
SPI_LSB_FIRST implemented and the mode_bits is so short that we
don't need a macro there.

According to John Crispin (aka blogic) on IRC on Nov 26 2018:
so basically i made cs1 work for MTK/labs when i built
the linkit smart for them. the req-sheet said that cs1 should be proper
duplex spi. however ....
1) the core will always send 1 byte before any transfer, this is the
m25p80 command.
2) mode 3 is broken and bit reversed (?)
3) some bit are incorrectly wired in hw for mode2/3
we wrote a test script and test for [0-0xffff] on all modes and certain
bits are swizzled under certain conditions and it was not possible to
fix this even using a hack.
we then decided to use spi-gpio and i never removed the errornous code
basically the spi is fecked for anything but half duplex spi mode0
running a sflash on it
The controller will always send some data from OPCODE register under half
duplex mode before starting a full-duplex transfer, so the full-duplex
mode is broken.
This piece of code also make CS1 unavailable since it forces the
broken full-duplex mode to be used on CS1.

Adding an extra MI_STORE_DWORD_IMM to the gpu relocation path for gen3
was good, but still not good enough. To survive 24+ hours under test we
needed to perform not one, not two but three extra store-dw. Doing so
for each GPU relocation was a little unsightly and since we need to
worry about userspace hitting the same issues, we should apply the dummy
store-dw into the EMIT_FLUSH.

Currently we allocate a scratch page for each engine, but since we only
ever write into it for post-sync operations, it is not exposed to
userspace nor do we care for coherency. As we then do not care about its
contents, we can use one page for all, reducing our allocations and
avoid complications by not assuming per-engine isolation.
For later use, it simplifies engine initialisation (by removing the
allocation that required struct_mutex!) and means that we can always rely
on there being a scratch page.

Braswell is really picky about having our writes posted to memory before
we execute or else the GPU may see stale values. A wmb() is insufficient
as it only ensures the writes are visible to other cores, we need a full
mb() to ensure the writes are in memory and visible to the GPU.
The most frequent failure in flushing before execution is that we see
stale PTE values and execute the wrong pages.

Add implementation of Spectrum-2 multicast routes for both IPv4 and IPv6 by
using ACL module explicitly.
In Spectrum-2, multicast routes are set as ACL rules, so initialization
takes care of creating dedicated ACL groups and binding them to the
appropriate multicast routing protocol IPv4/IPv6, and afterwards routes
configuration translates to setting explicit ACL rules.

In Spectrum-2, higher priority value wins and priority valid values are in
the range of {1,cap_kvd_size-1}. mlxsw_sp_acl_tcam_priority_get converts
from lower-bound priorities alike tc flower to Spectrum-2 HW range. Up
until now tc flower did not provide priority 0 or reached the maximal
value, however multicast routing does provide priority 0.
Therefore, Change mlxsw_sp_acl_tcam_priority_get to verify priority is in
the correct range. Make sure priority is never set to zero and never

Up until now, when ACL rule was created its action was created with it.
It suits well for tc flower where ACL rule always needs an action, however
it does not suit multicast router, where the action is created prior to
setting a route, which in Spectrum-2 is actually an ACL rule.
Add support for rule creation without action creation. Do it by adding
afa_block argument to mlxsw_sp_acl_rule_create, which if NULL then an
action would be created, also add an indication within struct
mlxsw_sp_acl_rule_info that tells if the action should be destroyed when
the rule is destroyed.

Multicast routes actions may be updated after creation. An example for that
is an addition of an egress interface to an existing route.
So far, as tc flower API dictated, ACL rules were either created or
deleted. Since multicast routes in Spectrum-2 are written to ACL as any
rule, it is required to allow the update of a rule's action as it may
change.
Add methods and operations to support updating rule's action. This is
supported only for Spectrum-2.
