("usb: host: xhci: Support running urb giveback in tasklet context").
The handle_irq_event_* functions are expected to be called with interrupts
disabled and they rightfully complain here because we run in tasklet context
with interrupts enabled.
Use a event spinlock to protect event handler from being interrupted.
Note, that there are only two users of this GPIO and ADC drivers and both of
them are using generic_handle_irq() which makes above happen.

mfd: madera: Improve handling of regulator unbinding
The current unbinding process for Madera has some issues. The trouble
is runtime PM is disabled as the first step of the process, but
some of the drivers release IRQs causing regmap IRQ to issue a
runtime get which fails. To allow runtime PM to remain enabled during
mfd_remove_devices, the DCVDD regulator must remain available. In
the case of external DCVDD's this is simple, the regulator can simply
be disabled/put after the call to mfd_remove_devices. However, in
the case of an internally supplied DCVDD the regulator needs to be
released after the other MFD children depending on it.
Use the new MFD mfd_remove_devices_late functionality to split
the DCVDD regulator off from the other drivers.

mfd: mfd-core: Add mechanism for removal of a subset of children
Currently, the only way to remove MFD children is with a call to
mfd_remove_devices, which will remove all the children. Under
some circumstances it is useful to remove only a subset of the
child devices. For example if some additional clean up is required
between removal of certain child devices.
To accomplish this a level field is added to mfd_cell, the normal
mfd_remove_devices is modified to not remove devices that are set
to a higher level and a corresponding mfd_remove_devices_late
function is added to remove those children.

The current implementation performs checking in the i2c_probe()

check for variant code will always default to using the BB tables
and will never select AD. The variant code is subsequently set
by device_init() and later used by the RTC so really it's a little
fortunate this mismatch works.
This update adds raw I2C read access functionality to read the chip

it can subsequently correctly choose the proper regmap tables for

mfd: core: Make a best effort attempt to match devices with the correct of_nodes
Currently, when a child platform device (sometimes referred to as a
sub-device) is registered via the Multi-Functional Device (MFD) API,
the framework attempts to match the newly registered platform device
with its associated Device Tree (OF) node. Until now, the device has
been allocated the first node found with an identical OF compatible
string. Unfortunately, if there are, say for example '3' devices
which are to be handled by the same driver and therefore have the same
compatible string, each of them will be allocated a pointer to the
*first* node.
An example Device Tree entry might look like this:
mfd_of_test {
compatible = "mfd,of-test-parent";
#address-cells = <0x02>;
#size-cells = <0x02>;
child@
aaaaaaaaaaaaaaaa {
compatible = "mfd,of-test-child";
reg = <0xaaaaaaaa 0xaaaaaaaa 0 0x11>,
<0xbbbbbbbb 0xbbbbbbbb 0 0x22>;
};
child@
cccccccc {
compatible = "mfd,of-test-child";
reg = <0x00000000 0xcccccccc 0 0x33>;
};
child@
dddddddd00000000 {
compatible = "mfd,of-test-child";
reg = <0xdddddddd 0x00000000 0 0x44>;
};
};
When used with example sub-device registration like this:
static const struct mfd_cell mfd_of_test_cell[] = {
OF_MFD_CELL("mfd-of-test-child", NULL, NULL, 0, 0, "mfd,of-test-child"),
OF_MFD_CELL("mfd-of-test-child", NULL, NULL, 0, 1, "mfd,of-test-child"),
OF_MFD_CELL("mfd-of-test-child", NULL, NULL, 0, 2, "mfd,of-test-child")
};
... the current implementation will result in all devices being allocated
the first OF node found containing a matching compatible string:
[0.712511] mfd-of-test-child mfd-of-test-child.0: Probing platform device: 0

[0.713889] mfd-of-test-child mfd-of-test-child.2: Using OF node: child@
dddddddd00000000
Which is fine if all OF nodes are identical. However if we wish to
apply an attribute to particular device, we really need to ensure the
correct OF node will be associated with the device containing the
correct address. We accomplish this by matching the device's address
expressed in DT with one provided during sub-device registration.
Like this:
static const struct mfd_cell mfd_of_test_cell[] = {
OF_MFD_CELL_REG("mfd-of-test-child", NULL, NULL, 0, 1, "mfd,of-test-child", 0xdddddddd00000000),
OF_MFD_CELL_REG("mfd-of-test-child", NULL, NULL, 0, 2, "mfd,of-test-child", 0xaaaaaaaaaaaaaaaa),
OF_MFD_CELL_REG("mfd-of-test-child", NULL, NULL, 0, 3, "mfd,of-test-child", 0x00000000cccccccc)
};
This will ensure a specific device (designated here using the
platform_ids; 1, 2 and 3) is matched with a particular OF node:
[0.712511] mfd-of-test-child mfd-of-test-child.0: Probing platform device: 0
[0.712710] mfd-of-test-child mfd-of-test-child.0: Using OF node: child@

This implementation is still not infallible, hence the mention of
"best effort" in the commit subject. Since we have not *insisted* on
the existence of 'reg' properties (in some scenarios they just do not
make sense) and no device currently uses the new 'of_reg' attribute,
we have to make an on-the-fly judgement call whether to associate the
OF node anyway. Which we do in cases where parent drivers haven't
specified a particular OF node to match to. So there is a *slight*
possibility of the following result (note: the implementation here is
convoluted, but it shows you one means by which this process can
still break):
/*
* First entry will match to the first OF node with matching compatible
* Second will fail, since the first took its OF node and is no longer available
* Third will succeed

We could code around this with some pre-parsing semantics, but the
added complexity required to cover each and every corner-case is not
justified. Merely patching the current failing (via this patch) is
already working with some pretty small corner-cases. Other issues
should be patched in the parent drivers which can be achieved simply
by implementing OF_MFD_CELL_REG().

type size_t is passed in from the userspace handlers. In order

need to cast them both to the same as the receiving size_t typed

It appears as though the driver data property 'resource_size_t *base'
was being used to store 2 different types of addresses (physical and
IO-mapped) under a single declared type.
Fortunately, no value is recalled from the driver data entry, so it
can be easily omitted. Instead we can use the value obtained directly
from the platform resource to pass through Regmap into the call-backs
to be used for the SMCC call and use a local dedicated __iomem
variable for IO-remapping.

Revert "btrfs: switch to iomap_dio_rw() for dio"
This reverts commit
a43a67a2d715540c1368b9501a22b0373b5874c0.
This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.
The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.
Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.
There have been discussions how to fix that, but revert seems to be the
least intrusive option.

net: ethernet: ti: ale: fix allmulti for nu type ale
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit
9d1f6447274f ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").
Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
