ARM: at91: pm: configure wakeup sources for ULP1 mode
Since for ULP1 PM mode of SAMA5D2 the wakeup sources are limited and
well known add a method to check if these wakeup sources are defined by
user (either via DT or filesystem). In case there are no wakeup sources
defined for ULP1 the PM suspend will fail, otherwise these will be
configured in fast startup registers of PMC. Since wakeup sources of
ULP1 need also to be configured in SHDWC registers the code was a bit
changed to map the SHDWC also in case ULP1 is requested by user (this
was done in the initialization phase). In case the ULP1 initialization
fails the ULP0 mode is used (this mode was also used in case backup mode
initialization failed).

ARM: at91: pm: Add ULP1 mode support
In the ULP1 mode, in order to achieve the lowest power consumption
with the system in retention mode and be able to resume on the wake
up events, all the clocks are shut off, inclusive the embedded 12MHz
RC oscillator, and the number of wake up sources is limited as well.
When the wake up event is asserted, the embedded 12MHz RC oscillator
restarts automatically.
The ULP1 (Ultra Low-power mode 1) is introduced by SAMA5D2.
The previous size of pm_suspend.o was 2148 bytes. With the addition of
ULP1 mode the new size of pm_suspend.o raised at 2456 bytes.

ARM: trusted_foundations: do not use naked function
As documented in GCC naked functions should only use basic ASM
syntax. The extended ASM or mixture of basic ASM and "C" code is
not guaranteed. Currently this works because it was hard coded
to follow and check GCC behavior for arguments and register
placement.
Furthermore with clang using parameters in Extended asm in a
naked function is not supported:
arch/arm/firmware/trusted_foundations.c:47:10: error: parameter
references not allowed in naked functions
: "r" (type), "r" (arg1), "r" (arg2)

the use of local_irq_disable/enable. This is no longer true as the
RTC+DDR path makes a late call during the suspend path after irqs
have been disabled to enable the RTC hwmod which calls both unlock and
lock, leading to IRQs being reenabled through the local_irq_enable call
in omap_hwmod_rtc_lock call.
To avoid this change the local_irq_disable/enable to
local_irq_save/restore to ensure that from whatever context this is
called the proper IRQ configuration is maintained.

ARM: OMAP1: ams-delta: move late devices back to init_machine
Initialization of several Amstrad Delta devices was once moved to
late_initcall by commit
f7519d8c8290 ("ARM: OMAP1: ams-delta: register
latch dependent devices later"). The purpose of that move was to allow
smooth conversion of Amstrad Delta latches to GPIO.
After successful conversion only ams_delta_serio driver was moved back
to device_initcall by commit
8d09a1bb3147 ("input: serio: ams-delta:
toggle keyboard power over GPIO"). Registration of ams-delta-nand and
lcd_ams_delta devices was kept in late_initcall in order to avoid
corrupt data reported by the serio driver on boot. Registration of
cx20442-codec device was kept there for it to be probed after a
regulator on which it depended was ready.
The issue of "keybrd_dataout" GPIO pin not initilized to GPIO_OUT_LOW
before other latch2 pins causing the corruption have been apparently
fixed by commit
5322c19b117a ("ARM: OMAP1: ams-delta: Hog
"keybrd_dataout" GPIO pin"). In turn, the issue of missing regulator
has been fixed by commit
50c678772a0b ("ASoC: cx20442: Don't ignore
regulator_get() errors.").
Simplify the board init code by moving registration of those devices
back to init_machine.

Pull block fixes from Jens Axboe:
"Small set of fixes for this series. Mostly just minor fixes, the only
oddball in here is the sg change.
The sg change came out of the stall fix for NVMe, where we added a
mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
sort-of ruins that, since we'd need to account for that. That's
actually a generic problem, since lots of drivers need to allocate SG
lists. So this just removes support for CONFIG_SG_DEBUG, which I added
back in 2007 and to my knowledge it was never useful.
Anyway, outside of that, this pull contains:
- clone of request with special payload fix (Bart)
- drbd discard handling fix (Bart)
- SATA blk-mq stall fix (me)
- chunk size fix (Keith)
- double free nvme rdma fix (Sagi)"

blk-mq: don't queue more if we get a busy return
Some devices have different queue limits depending on the type of IO. A
classic case is SATA NCQ, where some commands can queue, but others
cannot. If we have NCQ commands inflight and encounter a non-queueable
command, the driver returns busy. Currently we attempt to dispatch more
from the scheduler, if we were able to queue some commands. But for the
case where we ended up stopping due to BUSY, we should not attempt to
retrieve more from the scheduler. If we do, we can get into a situation
where we attempt to queue a non-queueable command, get BUSY, then
successfully retrieve more commands from that scheduler and queue those.
This can repeat forever, starving the non-queuable command indefinitely.
Fix this by NOT attempting to pull more commands from the scheduler, if
we get a BUSY return. This should also be more optimal in terms of
letting requests stay in the scheduler for as long as possible, if we
get a BUSY due to the regular out-of-tags condition.

dm: prevent DAX mounts if not supported
Currently device_supports_dax() just checks to see if the QUEUE_FLAG_DAX
flag is set on the device's request queue to decide whether or not the
device supports filesystem DAX. Really we should be using
bdev_dax_supported() like filesystems do at mount time. This performs
other tests like checking to make sure the dax_direct_access() path works.
We also explicitly clear QUEUE_FLAG_DAX on the DM device's request queue if
any of the underlying devices do not support DAX. This makes the handling
of QUEUE_FLAG_DAX consistent with the setting/clearing of most other flags
in dm_table_set_restrictions().
Now that bdev_dax_supported() explicitly checks for QUEUE_FLAG_DAX, this
will ensure that filesystems built upon DM devices will only be able to
mount with DAX if all underlying devices also support DAX.

Half of them are the regression fixes for CA0132 HD-audio codec, and
the rest are, again, a few more fixups for HD-audio, two UBSAN fixes
in the core ioctls, and a trivial fix in the error path handling in
lx6464es driver"

Pull mtd fixes from Boris Brezillon:
"NAND fixes:
- add a quirk for a bunch of broken Macronix chips
- fix nand_block_bad() when chip->ecc.read_oob() returns a positive
value encoding the number of bitflips
- fix OOB handling in the MXC driver fo V2.1 controllers
- flag the ONFI_FEATURE_ON_DIE_ECC as supported in the Micron driver
- hardcode clk rate in the denali_dt driver to address a bad DT
representation (the proper fix will be queued for 4.19)
SPI NOR fixes:
- add an ULL constant to some ID definitions so that the ID is not
truncated on 32-bit platforms
MTD fixes:
- fix the sector unlocking logic in the CFI driver"
