Fix link error when TOUCHSCREEN_RASPBERRYPI_FW is enabled as a module and
the dependent module is built-in. The 'depends on RASPBERRYPI_FIRMWARE' by
itself prevents the touchscreen driver from being built-in when the
firmware is configured as a module. However, the '|| COMPILE_TEST' still
allows it unless we explicitly prevent that configuration with
'|| (RASPBERRYPI_FIRMWARE=n && COMPILE_TEST)'.
ld: drivers/input/touchscreen/raspberrypi-ts.o: in function `rpi_ts_probe':
raspberrypi-ts.c:(.text+0x3a8): undefined reference to `rpi_firmware_get'
ld: raspberrypi-ts.c:(.text+0x3a8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `rpi_firmware_get'

ld: raspberrypi-ts.c:(.text+0x4c8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `rpi_firmware_property'
Rework so that TOUCHSCREEN_RASPBERRYPI_FW depends on
RASPBERRYPI_FIRMWARE=n if COMPILE_TEST is enabled.

On most newer Allwinner SoCs, there are two pinctrl devices, the PIO and
R_PIO. PIO covers pin-banks PA to PI (PJ and PK have not been seen),
while R_PIO covers PL to PN. The regulator array only has space for 12
entries, which was designed to cover PA to PL. On the A80, the pin banks
go up to PN, which would be the 14th entry in the regulator array.
However since the driver only needs to track regulators for its own pin
banks, the array only needs to have 9 entries, and also take in to
account the value of pin_base, such that the regulator for the first
pin-bank of the pinctrl device, be it "PA" or "PL" uses the first entry
of the array.
Base the regulator array index on pin_base, such that "PA" for PIO and
"PL" for R_PIO both take the first element within their respective
device's regulator array.
Also decrease the size of the regulator array to 9, just enough to cover
"PA" to "PI".

The new per-pin-bank regulator handling code in the sunxi pinctrl driver
has mismatched conditions for enabling and disabling the regulator: it
is enabled each time a pin is requested, but only disabled when the
pin-bank's reference count reaches zero.
Since we are doing reference counting already, there's no need to enable
the regulator each time a pin is requested. Instead we can just do it
for the first requested pin of each pin-bank. Thus we can reverse the
test and bail out early if it's not the first occurrence.

There is a bug in the current GPIO code for ftdi_sio: it failed to take USB
autosuspend into account. If the device is in autosuspend, calls to
usb_control_msg() fail with -EHOSTUNREACH. Because the standard value for
autosuspend timeout is usually 2-5 seconds, this made it almost impossible
to use the GPIOs on machines that have USB autosuspend enabled. This patch
fixes the issue by acquiring a PM lock on the device for the duration of
the USB transfers. Tested on an FT231X device.

Because the irq was requested through device managed resources API
(devm_request_threaded_irq()) it was freed after meson_mmc_remove()
completion, thus after mmc_free_host() has reclaimed meson_host memory.
As this irq is IRQF_SHARED, while using CONFIG_DEBUG_SHIRQ, its handler
get called by free_irq(). So meson_mmc_irq() was called after the
meson_host memory reclamation and was using invalid memory.
We ended up with the following scenario:
device_release_driver()
meson_mmc_remove()
mmc_free_host() /* Freeing host memory */
...
devres_release_all()
devm_irq_release()
__free_irq()
meson_mmc_irq() /* Uses freed memory */
To avoid this, the irq is released in meson_mmc_remove() and in
mseon_mmc_probe() error path before mmc_free_host() gets called.

OUT endpoint requests may somtimes have this flag set when
preparing to be submitted to HW indicating that there is an
additional TRB chained to the request for alignment purposes.
If that request is removed before the controller can execute the
transfer (e.g. ep_dequeue/ep_disable), the request will not go
through the dwc3_gadget_ep_cleanup_completed_request() handler
and will not have its needs_extra_trb flag cleared when
dwc3_gadget_giveback() is called. This same request could be
later requeued for a new transfer that does not require an
extra TRB and if it is successfully completed, the cleanup
and TRB reclamation will incorrectly process the additional TRB
which belongs to the next request, and incorrectly advances the
TRB dequeue pointer, thereby messing up calculation of the next
requeust's actual/remaining count when it completes.
The right thing to do here is to ensure that the flag is cleared
before it is given back to the function driver. A good place
to do that is in dwc3_gadget_del_and_unmap_request().

Pull ARM SoC fixes from Olof Johansson:
"A bigger batch than I anticipated this week, for two reasons:
- Some fallout on Davinci from board file -> DTB conversion, that
also includes a few longer-standing fixes (i.e. not recent
regressions).
- drivers/reset material that has been in linux-next for a while, but
didn't get sent to us until now for a variety of reasons
(maintainer out sick, holidays, etc). There's a functional
dependency in there such that one platform (Altera's SoCFPGA) won't
boot without one of the patches; instead of reverting the patch
that got merged, I looked at this set and decided it was small
enough that I'll pick it up anyway. If you disagree I can revisit
with a smaller set.
That being said, there's also a handful of the usual stuff:
- Fix for a crash on Armada 7K/8K when the kernel touches
PSCI-reserved memory
- Fix for PCIe reset on Macchiatobin (Armada 8K development board,
what this email is sent from in fact :)

Late reset controller changes for v5.0
This adds missing deassert functionality to the ARC HSDK reset driver,
fixes some indentation and grammar issues in the kernel docs, adds a
helper to count the number of resets on a device for the non-DT case
as well, adds an early reset driver for SoCFPGA and simple reset driver
support for Stratix10, and generalizes the uniphier USB3 glue layer

Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.
Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.
Fix the build by:
1) Renaming Marvell's defined value to a more scoped name,
in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
2) Adding the missing enum, which was going to be added anyway as part
of [1].

Pull dma_zalloc_coherent() removal from Christoph Hellwig:
"We've always had a weird situation around dma_zalloc_coherent. To
safely support mapping the allocations to userspace major
architectures like x86 and arm have always zeroed allocations from
dma_alloc_coherent, but a couple other architectures were missing that
zeroing either always or in corner cases.
Then later we grew anothe dma_zalloc_coherent interface to explicitly
request zeroing, but that just added __GFP_ZERO to the allocation
flags, which for some allocators that didn't end up using the page
allocator ended up being a no-op and still not zeroing the
allocations.
So for this merge window I fixed up all remaining architectures to
zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a
no-op wrapper around dma_alloc_coherent, which fixes all of the above
issues.
dma_zalloc_coherent is now pointless and can go away, and Luis helped
me writing a cocchinelle script and patch series to kill it, which I
think we should apply now just after -rc1 to finally settle these
issue"

When allocating memory pages for context memory, if the last page table
should be fully populated, the current code will set nr_pages to 0 when
calling bnxt_alloc_ctx_mem_blk(). This will cause the last page table
to be completely blank and causing some RDMA failures.
Fix it by setting the last page table's nr_pages to the remainder only
if it is non-zero.

Prior to this commit there were 3 issues with our handling of the TS-pin:
1) There are 2 ways how the firmware can disable monitoring of the TS-pin
for designs which do not have a temperature-sensor for the battery:
a) Clearing bit 0 of the AXP20X_ADC_EN1 register
b) Setting bit 2 of the AXP288_ADC_TS_PIN_CTRL monitoring
Prior to this commit we were unconditionally setting both bits to the
value used on devices with a TS. This causes the temperature protection to
kick in on devices without a TS, such as the Jumper ezbook v2, causing
them to not charge under Linux.
This commit fixes this by using regmap_update_bits when updating these 2
registers, leaving the 2 mentioned bits alone.
The next 2 problems are related to our handling of the current-source
for the TS-pin. The current-source used for the battery temp-sensor (TS)
is shared with the GPADC. For proper fuel-gauge and charger operation the
TS current-source needs to be permanently on. But to read the GPADC we
need to temporary switch the TS current-source to ondemand, so that the
GPADC can use it, otherwise we will always read an all 0 value.
2) Problem 2 is we were writing hardcoded values to the ADC TS pin-ctrl
register, overwriting various other unrelated bits. Specifically we were
overwriting the current-source setting for the TS and GPIO0 pins, forcing
it to 80ųA independent of its original setting. On a Chuwi Vi10 tablet
this was causing us to get a too high adc value (due to a too high
current-source) resulting in the following errors being logged:
ACPI Error: AE_ERROR, Returned by Handler for [UserDefinedRegion]
ACPI Error: Method parse/execution failed \_SB.SXP1._TMP, AE_ERROR
This commit fixes this by using regmap_update_bits to change only the
relevant bits.
3) After reading the GPADC channel we were unconditionally enabling the
TS current-source even on devices where the TS-pin is not used and the
current-source thus was off before axp288_adc_read_raw call.
This commit fixes this by making axp288_adc_set_ts a nop on devices where
the ADC is not enabled for the TS-pin.

After Commit 54aed4dd3526 ("MIPS: IP27: use dma_direct_ops") qla1280 driver
failed on SGI IP27 machines with
qla1280: QLA1040 found on PCI bus 0, dev 0

qla1280: Failed to get request memory
qla1280: probe of 0000:00:00.0 failed with error -12
Reason is that SGI IP27 always generates 64bit DMA addresses and has no
fallback mode for 32bit DMA addresses implemented. QLA1280 supports 64bit
addressing for all DMA accesses so setting coherent mask to 64bit fixes the
issue.

When SCSI-MQ is enabled, in some case system would present
nr_possible_cpus() which is greater than requested vectors by the
driver. This results into driver being able to get larger number of MSI-X
vectors than actual online CPUs. Driver then uses
pci_alloc_irq_vectors_affinity() to assign 1:1 mapping and affinity for
each MSI-x vector to CPUs. When the command is submitted using MSI-x
vector, assigned to offline CPU, it results in an ABTS and system
hang. This hang is result of a driver not being able to process interrupt
on a vector assigned to an Off-line CPUs
This patch fixes this issue by setting irq_offset value for the
blk_mq_pci_map_queues() to use only those CPUs which has CPU mask affinity
assigned and are online. By using the irq_offset value, driver will allow
online cpumask to decide which vectors are used in blk_mq_pci_map_queues().

One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.
