Fireworks uses TSB43CB43(IceLynx-Micro) as its IEC 61883-1/6 interface.
This chip includes ARM7 core, and loads and runs program. The firmware
is stored in on-board memory and loaded every powering-on.
Echo Audio ships several versions of firmwares for each model. These
firmwares have each quirk and the quirk changes a sequence of packets.
AudioFire2 has a quirk to transfer a first packet with non-zero in
its dbc field. This causes ALSA Fireworks driver to detect discontinuity.
As long as I investigated, firmware 5.7, 5.7.6 and 5.8 have this quirk.
This commit adds a support for the quirk to handle AudioFire2 packets.
For safe, CIP_SKIP_INIT_DBC_CHECK is applied to all versions of
AudioFire2's firmwares.

A regular TX WQE execution involves two or more DMA reads -
one to fetch the WQE, and another one per WQE gather entry.
These DMA reads obviously increase the TX latency.
There are two mlx5 mechanisms to bypass these DMA reads:
1) Inline WQE
2) Blue Flame (BF)
An inline WQE contains a whole packet, thus saves the DMA read/s
of the regular WQE gather entry/s. Inline WQE support was already
added in the previous commit.
A BF WQE is written directly to the device I/O mapped memory, thus
enables saving the DMA read that fetches the WQE.
The BF WQE I/O write must be in cache line granularity, thus uses
the CPU write combining mechanism.
A BF WQE I/O write acts also as a TX doorbell for notifying the
device of new TX WQEs.
A BF WQE is written to the same I/O mapped address as the regular TX
doorbell, thus this address is being mapped twice - once by ioremap()
and once by io_mapping_map_wc().
While both mechanisms reduce the TX latency, they both consume more CPU
cycles than a regular WQE:
- A BF WQE must still be written to host memory, in addition to being
written directly to the device I/O mapped memory.
- An inline WQE involves copying the SKB data into it.
To handle this tradeoff, we introduce here a heuristic algorithm that
strives to avoid using these two mechanisms in case the TX queue is
being back-pressured by the device, and limit their usage rate otherwise.
An inline WQE will always be "Blue Flamed" (written directly to the
device I/O mapped memory) while a BF WQE may not be inlined (may contain
gather entries).
Preliminary testing using netperf UDP_RR shows that the latency goes down
from 17.5us to 16.9us, while the message rate (tested with pktgen) stays
the same.

Our irq-bcm7120-l2 interrupt controller driver utilizes the same handler
function for the different parent interrupts it services: UPG_MAIN, UPG_BSC for
instance.
The problem is that function reads the IRQSTAT register which can combine
interrupt causes for different parent interrupts, such that we can end-up in
the following situation:
- CPU takes an interrupt
- bcm7120_l2_intc_irq_handle() reads IRQSTAT
- generic_handle_irq() is invoked
- there are still pending interrupts flagged in IRQSTAT from a different parent
- handle_bad_irq() is invoked for these since they come from a different irq_desc/irq
In order to fix this, make sure that we always mask IRQSTAT with the
appropriate bits that correspond go the parent interrupt source this is coming
from. To simplify things, associate an unique structure per parent interrupt
handler to avoid multiplying the number of lookups.

Make use of the new irq_chip_generic suspend/resume callbacks.
This is required because if there are no installed child IRQs for this
chip, the irq_chip::irq_{suspend,resume} functions will not be called.
However, we still need to save/restore the forwarding mask, to enable
the top-level GIC interrupt; otherwise, we lose UART output after S3
resume.
In addition to refactoring the callbacks, we have to self-initialize the
mask cache, since the genirq core also doesn't initialize this until the
first child IRQ is installed.

Some (admittedly odd) irqchips perform functions that are not directly
related to any of their child IRQ lines, and therefore need to perform
some tasks during suspend/resume regardless of whether there are
any "installed" interrupts for the irqchip. However, the current
generic-chip framework does not call the chip's irq_{suspend,resume}
when there are no interrupts installed (this makes sense, because there
are no irq_data objects for such a call to be made).
More specifically, irq-bcm7120-l2 configures both a forwarding mask
(which affects other top-level GIC IRQs) and a second-level interrupt
mask (for managing its own child interrupts). The former must be
saved/restored on suspend/resume, even when there's nothing to do for
the latter.
This patch adds a new set of suspend/resume hooks to irq_chip_generic,
to help represent *chip* suspend/resume, rather than IRQ suspend/resume.
These callbacks will always be called for an IRQ chip (regardless of the
installed interrupts) and are based on the per-chip irq_chip_generic
struct, rather than the per-IRQ irq_data struct.

Init data marked const should be annotated with __initconst for
correctness and not __initdata. And for those already __initconst,
they should be qualified as const at the compiler level too.
This also fixes LTO builds that otherwise fail with section mismatch
errors.

Now that the GIC chip implementation enables IRQCHIP_SKIP_SET_WAKE and
IRQCHIP_MASK_ON_SUSPEND by default, the platforms requiring them need
not override the irqchip flags as before.
This patch removes all the users of gic_set_irqchip_flags and the
function itself.
