staging: nvec: explicitly request exclusive reset control
Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.
No functional changes.

The recent reshuffling of header files left one type definition
missing in some configurations:
In file included from drivers/staging/fsl-dpaa2/ethernet/dpaa2-eth.h:39:0,
from drivers/staging/fsl-dpaa2/ethernet/dpaa2-ethtool.c:34:
drivers/staging/fsl-dpaa2/ethernet/../../fsl-mc/include/dpaa2-io.h:86:1: error: unknown type name 'irqreturn_t'; did you mean 'irq_count'?
irqreturn_t dpaa2_io_irq(struct dpaa2_io *obj);
I have not bisected this to the exact patch that introduced the problem,
but the solution is obvious, we just need to include the header that
contains the type.
staging: fsl-mc/dpio: Skip endianness conversion in portal config
Writing to the register using writel does the CPU to LE conversion down the
line, so it's not required here. Doing it breaks portal configuration on
big endian kernels.
Once a Tx frame descriptor is enqueued, an interrupt might be triggered
to process the Tx confirmation and free the skb, hitting a memory use
after free when updating the tx_bytes statistic based on skb->len.
staging: fsl-mc: allow the driver compile multi-arch
Add an alternate dependency on COMPILE_TEST, thus leaving
this driver compile on other architectures.
Also, other drivers depending on the bus are updated to depend
on ARCH_LAYERSCAPE until they'll also be made multi-arch.
This was compiled tested on:
- booke powerpc (corenet{32,64}_smp_defconfig)
- x86 (i386_defconfig, x86_64_defconfig, needs CONFIG_OF)
- arm64 (defconfig)
staging: fsl-mc: make the driver compile on 32-bit
Since there's no real constrain in MC to do only atomic 64-bit we can
enable this driver on 32-bit platforms too.
Include linux/io-64-nonatomic-hi-lo.h to make quad device io apis used
in the driver available on 32-bit platforms.
staging: fsl-mc: don't use raw device io functions
As raw device io functions are not portable and don't handle byte-order
(triggering suspicion that endianness isn't handled well) switch to
using the standard api.
Since MC expects LE byte-order and the upper layers already take care
of that, we need to trick the device io api by doing a LE -> CPU
conversion just before calling it. This way, the CPU -> LE conversion
done in the api puts the data back in the right byte-order. Obviously,
for reads the extra step is mirrored: there's a CPU -> LE conversion
following the API call.
staging: fsl-mc: fix formating of phys_addr_t on 32 bits
Use correct format specifier for phys_addr_t variables (%pa) instead
of %llx. This fixes these warnings on 32 bit targets:
"format '%llx' expects argument of type 'long long unsigned int',
but argument 4 has type 'phys_addr_t' [-Wformat=]"

to set the xattr. The available __vfs_setxattr() function does
the same thing and also handles the case of when size is zero
the xattr should be set to empty EA.
staging: lustre: llite: add xattr.h header to xattr.c

with const attribute_group. So mark the non-const structs as const.

First round of IIO new device support, features and cleanups for the 4.14 cycle.
4 completely new drivers in this set and plenty of other stuff.
One ABI change due to a silly mistake a long time back. Hopefully no
one will notice. It effects the numerical order of consumer device
channels which was the reverse of the obvious. It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)
New Device Support
* ccs811
- new driver for the Volatile Organic Compounds (VOC) sensor.
* dln2 adc
- new driver for the ADC on this flexible usb board.
* EP93xx
- new driver for this Cirrus logic SoC ADC.
* ltc2471
- new ADC driver support the ltc2471 and ltc2473
* st_accel
- add trivial table entries to support H3LIS331DL, LIS331DL, LIS3LV02DL.
* st_gyro
- add L3GD20H support (again) having fixed the various things that were
broken in the first try. Includes devicetree binding.
* stm32 dac
- add support for the DACs in the STM32F4 series
Features
* Documentation
- add missing power attribute documentation to the ABI docs.
* at91-sama5d2
- add hardware trigger and buffered capture support with bindings.
- suspend and resume functionality.
* bmc150
- support for the BOSC0200 ACPI device id seen on some tablets.
* hdc100x
- devicetree bindings
- document supported devices
- match table and device ids.
* hts221
- support active low interrupts (with bindings)
- open drain mode with bindings.
* htu21
- OF match table and bindings.
* lsm6dsx
- open drain mode with bindings
* ltc2497
- add support for board file based consumer mapping.
* ms5367
- OF match table and bindings.
* mt7622
- binding document and OF match table.
- suspend and resume support.
* rpr0521
- triggered buffer support.
* tsys01
- OF match table and bindings.
Cleanups and minor fixes
* core
- fix ordering of IIO channels to entry numbers when using
iio_map_array_register rather than reversing them.
- use the new %pOF format specifier rather than full name for the
device tree nodes.
* ad7280a
- fix potential issue with macro argument reuse.
* ad7766
- drop a pointless NULL value check as it's done in the gpiod code.
* adis16400
- unsigned -> unsigned int.
* at91 adc
- make some init data static to reduce code size.
* at91-sama5d2 ADC
- make some init data static to reduce code size.
* da311
- make some init data static to reduce code size.
* hid-sensor-rotation
- drop an unnecessary static.
* hts221
- refactor the write_with_mask code.
- move the BDU configuration to probe time as there is no reason for it
to change.
- avoid overwriting reserved data during power-down. This is a fix, but
the infrastructure need was too invasive to send it to mainline except
in a merge window. It's not a regression as it was always wrong.
- avoid reconfigure the sampling frequency multiple times by just
doing it in the write_raw function directly.
- refactor the power_on/off calls into a set_enable.
- move the dry-enable logic into trig_set_state as that is the only
place it was used.
* ina219
- fix polling of ina226 conversion ready flag.
* imx7d
- add vendor name in kconfig for consistency with similar parts.
* mcp3422
- Change initial channel to 0 as it feels more logical.
- Check for some errors in probe.
* meson-saradc
- add a check of of_match_device return value.
* mpu3050
- allow open drain for any interrupt type.
* rockchip adc
- add check on of_match_device return value.
* sca3000
- drop a trailing whitespace.
* stm32 adc
- make array stm32h7_adc_ckmodes_spec static.
* stm32 dac
- fix an error message.
* stm32 timers
- fix clock name in docs to match reality after changes.
* st_accel
- explicit OF table (spi).
- add missing entries to OF table (i2c).
- rename of_device_id table to drop the part name.
- adding missing lis3l02dq entry to bindings.
- rename H3LIS331DL_DRIVER_NAME to line up with similar entries in driver.
* st_gyro
- explicit OF table (spi).
* st_magn
- explicit OF table (spi).
- enable multiread for lis3mdl.
* st_pressure
- explicit OF table (spi).
* st_sensors common.
- move st_sensors_of_i2c_probe and rename to make it available for spi
drivers.
* tsc3472
- don't write an extra byte when writing the ATIME register.
- add a link to the datasheet.
* tsl2x7x - continued staging cleanups
- add of_match_table.
- drop redundant power_state sysfs attribute.
- drop wrapper tsl2x7x_i2c_read.
- clean up i2c calls made in tsl2x7x_als_calibrate.
- refactor the read and write _event_value callbacks to handle additional
elements.
- use usleep_range instead of mdelay.
- check return value from tsl2x7x_invoke_change.
* zpa2326
- add some newline to the end of logging macros.

This adds a perl script to actually parse the MAINTAINERS file, clean up
some whitespace in it, warn about errors in it, and then properly sort
the end result.
My perl-fu is atrocious, so the script has basically been created by
randomly putting various characters in a pile, mixing them around, and
then looking it the end result does anything interesting when used as a
perl script.
Prepping for scripting the MAINTAINERS file cleanup (and possible split)
showed a couple of cases where the headers for a couple of entries were
bogus.
There's a few different kinds of bogosities:
- the X-GENE SOC EDAC case was confused and split over two lines
- there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all
different things.
- the NOKIA N900 CAMERA SUPPORT" was duplicated
all of which were more obvious when you started doing associative arrays
in perl to track these things by the header (so that we can alphabetize
this thing properly, and so that we might split it up by the data too).

xen/balloon: don't online new memory initially
xen/x86: fix cpu hotplug
xen/grant-table: log the lack of grants
xen/x86: Don't BUG on CPU0 offlining
When setting up the Xenstore watch for the memory target size the new
watch will fire at once. Don't try to reach the configured target size
by onlining new memory in this case, as the current memory size will
be smaller in almost all cases due to e.g. BIOS reserved pages.
Onlining new memory will lead to more problems e.g. undesired conflicts
with NVMe devices meant to be operated as block devices.
Instead remember the difference between target size and current size
when the watch fires for the first time and apply it to any further
size changes, too.
In order to avoid races between balloon.c and xen-balloon.c init calls
do the xen-balloon.c initialization from balloon.c.
Commit dc6416f1d711eb4c1726e845d653235dcaae12e1 ("xen/x86: Call
cpu_startup_entry(CPUHP_AP_ONLINE_IDLE) from xen_play_dead()")
introduced an error leading to a stack overflow of the idle task when
a cpu was brought offline/online many times: by calling
cpu_startup_entry() instead of returning at the end of xen_play_dead()
do_idle() would be entered again and again.
Don't use cpu_startup_entry(), but cpuhp_online_idle() instead allowing
to return from xen_play_dead().

xen/grant-table: log the lack of grants
log a message when we enter this situation:
1) we already allocated the max number of available grants from hypervisor
and
2) we still need more (but the request fails because of 1)).
Sometimes the lack of grants causes IO hangs in xen_blkfront devices.
Adding this log would help debuging.

CONFIG_BOOTPARAM_HOTPLUG_CPU0 allows to offline CPU0 but Xen HVM guests
BUG() in xen_teardown_timer(). Remove the BUG_ON(), this is probably a

just fine for HVM.
