This patch fixes two typos in the i2c_0 node for the ipq4019.
The reg property length is just 0x600. The core clock is
GCC_BLSP1_QUP1_I2C_APPS_CLK. GCC_BLSP1_QUP2_I2C_APPS_CLK is
used by the second i2c.

The Broadcom Stingray SoC is a new member in Broadcom iProc
SoC family.
This patch adds initial DTS files for Broadcom Stingray SoC
and two of its reference boards (bcm958742k and bcm958742t).
We have lot of reference boards and large number of devices
in Broadcom Stingray SoC so eventually we will have quite
a few DTS files for Stingray. To tackle, we have added a
separate directory for Stingray DTS files.

This allows to detect -s (--silent) option without checking GNU Make
version.
As commit e36aaea289 ("kbuild: Fix silent builds with make-4")
pointed out, GNU Make 4.x changed the way/order it presents the
command line options into MAKEFLAGS.
In Make 3.8x, 's' is always the first in a group of short options.
The group may be prefixed with '-' in some cases.
In Make 4.x, 's' is always the last in a group of short options.
As commit e6ac89fabd ("kbuild: Correctly deal with make options
which contain an 's'") addressed, we also need to deal with long
options that contain 's', like --warn-undefined-variables.
Test cases:
[1] command line input: make --silent
-> MAKEFLAGS for Make 3.8x: s
-> MAKEFLAGS for Make 4.x : s
[2] command line input: make -srR
-> MAKEFLAGS for Make 3.8x: sRr
-> MAKEFLAGS for Make 4.x : rRs
[3] command line input: make -s -rR --warn-undefined-variables
-> MAKEFLAGS for Make 3.8x: --warn-undefined-variables -sRr
-> MAKEFLAGS for Make 4.x : rRs --warn-undefined-variables
My idea to cater to all the cases more easily is to filter out long
options (--%), then search 's' with $(findstring ...). This way will
be more future-proof even if future versions of Make put 's' in the
middle of the group.

Linux IRQ #0 is reserved for error reporting and may not be used.
Increase NR_IRQS for one additional slot and increase
irq_domain_add_legacy parameter first_irq value to 1, so that linux
IRQ #0 is not associated with hardware IRQ #0 in legacy IRQ domains.
Introduce macro XTENSA_PIC_LINUX_IRQ for static translation of xtensa
PIC hardware IRQ # to linux IRQ #. Use this macro in XTFPGA platform
data definitions.
This fixes inability to use hardware IRQ #0 in configurations that don't
use device tree and allows for non-identity mapping between linux IRQ #
and hardware IRQ #.

The new per-cpu counter for writes_pending is initialised in
md_alloc(), which is not called by dm-raid.
So dm-raid fails when md_write_start() is called.
Move the initialization to the personality modules
that need it. This way it is always initialised when needed,
but isn't unnecessarily initialized (requiring memory allocation)
when the personality doesn't use writes_pending.

The stmfts (ST-Microelectronics FingerTip S) touchscreen device is a
capacitive multi-touch controller mainly for mobile use. It's connected
through i2c bus at the address 0x49 and it interfaces with userspace
through input event interface.
At the current state it provides a touchscreen multitouch functionality up
to 10 fingers. Each finger is enumerated with a distinctive id (from 0 to
9).
If enabled the device can support single "touch" hovering, by providing
three coordinates, x, y and distance.
It is possible to select the touchkey functionality which provides a basic
two keys interface for "home" and "back" menu, typical in mobile phones.

In case an assert happens on init flow, the current
driver powers down the NIC, except if iwlmvm modparam
init_dbg=1, and only on very specific flows.
Extend this capability to cover most failure cases
by keeping track of what init configurations have been
completed. This way, we can allow NOT powering down
the NIC, while making sure that when the driver is
removed we don't try to free resources that haven't
been allocated. (This can result in a kernel panic.)
