iio: adc: ti-ads7950: allow simultaneous use of buffer and direct mode
This modifies the TI ADS7950 A/DC driver to allow the simultaneous use
of both the triggered buffer and reading channels directly (via in-
kernel API or sysfs).
The use case for this is on LEGO MINDSTORMS EV3. Two of the voltage
channels are used in-kernel by a power supply driver, which reads the
values using iio_read_channel_processed(). These channels are only read
at a slow rate (<= 1Hz). However, we want to be able to read 12 other
channels at the same time using the triggered buffer at a high rate (>=
100Hz).

staging: rtlwifi: Fix a possible sleep-in-atomic-context bug in _is_fw_read_cmd_down()
The driver may sleep with holding a spinlock.

staging: rtsx: remove rtsx_trace() and related code
The driver has rather excessive amount of tracing code, which would be
better done using ftrace. This is obviously not a main feature of the
driver, and it should work just as well without it.
Removing it saves over 1300 lines of code and likely makes the driver
a bit faster by avoiding lots of calls into the timekeeping code.
I came across this while cleaning up the last users of the deprecated
getnstimeofday64() function, of which there is one in the now-removed
get_current_time() function of the rtsx driver that was only used for
tracing.

staging: use BIT_ULL for NL80211_STA_INFO_* attribute types
The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).
Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.
This commit cleans up all usages of BIT macro with the above field
in cfg80211 by changing it to BIT_ULL instead.

staging: mt7621-gpio: update Kconfig with SoC details
Kconfig is using a generic 'Mediatek GPIO Support' in
description and help which is not specific at all about
the current SoC which is MT7621. Update it.

staging: mt7621-gpio: set different names for each gpio_chip and irq_chip
Currently the driver defines 3 gpiochips, one for each bank.
/sys/class/gpio/gpiochip416/label:
1e000600.gpio
/sys/class/gpio/gpiochip448/label:
1e000600.gpio
/sys/class/gpio/gpiochip480/label:
1e000600.gpio
Unfortunately they all have the same label
Interrupts from /proc/interrupt show the same name which is
confusing:
/proc/interrupts:
17: 0 0 0 0 MIPS GIC 19 mt7621, mt7621, mt7621
which is the interrupt from the GPIO controller.
It is a little weird that all three banks are named "mt7621"
here. We also have:
26: 0 0 0 0 GPIO 18 reset
which is the interrupt from GPIO which provides the "reset"
button. I suspect that if I had interrupts form two different
banks they would both be called "GPIO" which would be a little
confusing.
In order to unify all of this set different names for each chip
Use a 'bank-based' name instead the same for all: 'mt7621-bank[0-2]'.
Create a new 'mediatek_gpio_bank_name' function which return the
name depending on the bank number. This function is allways called
with a valid index 0, 1 or 2.

staging: mt7621-gpio: avoid one level indentation in interrupt handler
There is no need to check for 'pending' before loop over the
interrupts using 'for_each_set_bit' if nothing is set the
return values will be the same so just avoid this check avoiding
also one level intentation and improving readability.

If there is no interrupt defined in the dts 'irq_of_parse_and_map'

staging: mt7621-gpio: remove no more necessary PIN_MASK macro
PIN_MASK macro was being used because of the fact we were only
using one interrupt controller for all of the gpio chips. This
has been changed to use one per gpio chip and each has 32 irqs.
Because of this this macro is not needed anymore. Use BIT macro
instead.

staging: mt7621-gpio: avoid custom irq_domain for gpio
Instead of create a custom irq_domain for this chip, use
'gpiochip_set_chained_irqchip' from GPIOLIB_IRQCHIP. It
is ok to call this function several times. We have to
manually mark the line with 'IRQF_SHARED' and then loop
over the three banks until you find a hit. There were
some problems with removing an irqchip like that but this
driver is a bool so it might work just fine. After this
changes the functions 'mediatek_gpio_to_irq' is not needed
anymore and also the 'gpio_irq_domain' field from the state
container. Instead of use the custom irq domain in the irq
handler use the associated domain from the gpio_chip in
'irq_find_mapping' function. Function 'mediatek_gpio_bank_probe'
has been moved a it to the botton to have all the irq related
functions together and avoid some forward declarations to resolve
some symbols along the code.
