Bartosz Golaszewski a54d03ed01 mailbox: tegra-hsp: use devm_kstrdup_const()
Use devm_kstrdup_const() in the tegra-hsp driver. This mostly serves as
an example of how to use this new routine to shrink driver code.

Also use devm_kzalloc() instead of regular kzalloc() to shrink the
driver even more.

Doorbell objects are only removed in the driver's remove callback so
it's safe to convert all memory allocations to devres.

Thierry Reding 9a63f0f405 mailbox: tegra-hsp: Add suspend/resume support
Upon resuming from a system sleep state, the interrupts for all active
shared mailboxes need to be reenabled, otherwise they will not work.

Thierry Reding 91b1b1c3da mailbox: tegra-hsp: Add support for shared mailboxes
The Tegra HSP block supports 'shared mailboxes' that are simple 32-bit
registers consisting of a FULL bit in MSB position and 31 bits of data.
The hardware can be configured to trigger interrupts when a mailbox
is empty or full. Add support for these shared mailboxes to the HSP
driver.

The initial use for the mailboxes is the Tegra Combined UART. For this
purpose, we use interrupts to receive data, and spinning to wait for
the transmit mailbox to be emptied to minimize unnecessary overhead.

Based on work by Mikko Perttunen <mperttunen@nvidia.com>.

Mikko Perttunen fed8b7e366 dt-bindings: tegra186-hsp: Add shared mailboxes
Shared mailboxes are a mechanism to transport data from one processor in
the system to another. They are bidirectional links with both a producer
and a consumer. Interrupts are used to let the consumer know when data
was written to the mailbox by the producer, and to let the producer know
when the consumer has read the data from the mailbox. These interrupts
are mapped to one or more "shared interrupts". Typically each processor
in the system owns one of these shared interrupts.

Add documentation to the device tree bindings about how clients can use
mailbox specifiers to request a specific shared mailbox and select which
direction they drive. Also document how to specify the shared interrupts
in addition to the existing doorbell interrupt.

Mikko Perttunen 8ed82e2387 mailbox: Allow multiple controllers per device
Look through the whole controller list when mapping device tree
phandles to controllers instead of stopping at the first one.

Each controller is intended to only contain one kind of mailbox,
but some devices (like Tegra HSP) implement multiple kinds and use
the same device tree node for all of them. As such, we need to allow
multiple mbox_controllers per device tree node.

Thierry Reding a8803d7421 mailbox: Support blocking transfers in atomic context
The mailbox framework supports blocking transfers via completions for
clients that can sleep. In order to support blocking transfers in cases
where the transmission is not permitted to sleep, add a new ->flush()
callback that controller drivers can implement to busy loop until the
transmission has been completed. A new mbox_flush() function can be
called by mailbox consumers in atomic context to make sure a transfer
has completed.

Enric Balletbo i Serra d347d0c82a backlight: pwm_bl: Fix brightness levels for non-DT case.
Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED
linearly to human eye")' allows the possibility to compute a default
brightness table when there isn't the brightness-levels property in the
DT. Unfortunately the changes made broke the pwm backlight for the
non-DT boards.

Usually, the non-DT boards don't pass the brightness levels via platform
data, instead, it sets the max_brightness in their platform data and the
driver calculates the level without a table. The offending patch assumed
that when there is no brightness levels table we should create one, but this
is clearly wrong for the non-DT case.

After this patch the code handles the DT and the non-DT case taking in
consideration also if max_brightness is set or not.

Or Gerlitz 35cc3cefc4 net/sched: cls_flower: Reject duplicated rules also under skip_sw
Currently, duplicated rules are rejected only for skip_hw or "none",
hence allowing users to push duplicates into HW for no reason.

====================
bnxt_en: Bug fixes.

The first patch fixes a regression on CoS queue setup, introduced
recently by the 57500 new chip support patches.  The rest are
fixes related to ring and resource accounting on the new 57500 chips.

Michael Chan e30fbc3319 bnxt_en: Fix _bnxt_get_max_rings() for 57500 chips.
The CP rings are accounted differently on the new 57500 chips.  There
must be enough CP rings for the sum of RX and TX rings on the new
chips.  The current logic may be over-estimating the RX and TX rings.

The output parameter max_cp should be the maximum NQs capped by
MSIX vectors available for networking in the context of 57500 chips.
The existing code which uses CMPL rings capped by the MSIX vectors
works most of the time but is not always correct.

Michael Chan c0b8cda05e bnxt_en: Fix NQ/CP rings accounting on the new 57500 chips.
The new 57500 chips have introduced the NQ structure in addition to
the existing CP rings in all chips.  We need to introduce a new
bnxt_nq_rings_in_use().  On legacy chips, the 2 functions are the
same and one will just call the other.  On the new chips, they
refer to the 2 separate ring structures.  The new function is now
called to determine the resource (NQ or CP rings) associated with
MSIX that are in use.

On 57500 chips, the RDMA driver does not use the CP rings so
we don't need to do the subtraction adjustment.

Michael Chan 75720e6323 bnxt_en: Keep track of reserved IRQs.
The new 57500 chips use 1 NQ per MSIX vector, whereas legacy chips use
1 CP ring per MSIX vector.  To better unify this, add a resv_irqs
field to struct bnxt_hw_resc.  On legacy chips, we initialize resv_irqs
with resv_cp_rings.  On new chips, we initialize it with the allocated
MSIX resources.

Michael Chan 804fba4e9f bnxt_en: Fix CNP CoS queue regression.
Recent changes to support the 57500 devices have created this
regression.  The bnxt_hwrm_queue_qportcfg() call was moved to be
called earlier before the RDMA support was determined, causing
the CoS queues configuration to be set before knowing whether RDMA
was supported or not.  Fix it by moving it to the right place right
after RDMA support is determined.
