bcm47xx_sprom.h did not include a prototype for bcm47xx_fill_sprom()
therefore add one, and make sure we do include that header to fix
-Wmissing-prototypes warnings.

The ioreadX() helpers have inconsistent interface. On some architectures
void *__iomem address argument is a pointer to const, on some not.
Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

Patch series "iomap: Constify ioreadX() iomem argument", v3.
The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.
It seems there is nothing really stopping all of them to take pointer to
const.
This patch (of 4):
The ioreadX() and ioreadX_rep() helpers have inconsistent interface. On
some architectures void *__iomem address argument is a pointer to const,
on some not.
Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

- Allow s390 debug feature to handle finally more than 256 CPU numbers,
instead of truncating the most significant bits.
- Improve THP splitting required by qemu processes by making use of
walk_page_vma() instead of calling follow_page() for every single
page within each vma.
- Add missing ZCRYPT dependency to VFIO_AP to fix potential compile
problems.
- Remove not required select CLOCKSOURCE_VALIDATE_LAST_CYCLE again.
- Set node distance to LOCAL_DISTANCE instead of 0, since e.g. libnuma
translates a node distance of 0 to "no NUMA support available".

The DT node full name is currently being used in regmap_config
which in turn is used to create the regmap debugfs directories.
This name however is not guaranteed to be unique and the regmap
debugfs registration can fail in the cases where the syscon nodes
have the same unit-address but are present in different DT node
hierarchies. Replace this logic using the syscon reg resource
address instead (inspired from logic used while creating platform
devices) to ensure a unique name is given for each syscon.

The handle_irq_event_* functions are expected to be called with interrupts
disabled and they rightfully complain here because we run in tasklet context

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

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.

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()
function of the variant_code but does this immediately after the
containing struct has been initialised as all zero. This means the
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
and variant/revision information (common to all revisions) so that
it can subsequently correctly choose the proper regmap tables for
real initialisation.

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
[0.712710] mfd-of-test-child mfd-of-test-child.0: Using OF node: child@aaaaaaaaaaaaaaaa

[0.713889] mfd-of-test-child mfd-of-test-child.2: Using OF node: child@aaaaaaaaaaaaaaaa
After this patch each device will be allocated a unique 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@aaaaaaaaaaaaaaaa

[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@dddddddd00000000

[0.713889] mfd-of-test-child mfd-of-test-child.2: Using OF node: child@cccccccc
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
*/
static const struct mfd_cell mfd_of_test_cell[] = {
OF_MFD_CELL("mfd-of-test-child", NULL, NULL, 0, 1, "mfd,of-test-child"),
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)
};
The result:
[0.753869] mfd-of-test-parent mfd_of_test: Registering 3 devices
[0.756597] mfd-of-test-child: Failed to locate of_node [id: 2]
[0.759999] mfd-of-test-child mfd-of-test-child.1: Probing platform device: 1
[0.760314] mfd-of-test-child mfd-of-test-child.1: Using OF node: child@aaaaaaaaaaaaaaaa
[0.760908] mfd-of-test-child mfd-of-test-child.2: Probing platform device: 2
[0.761183] mfd-of-test-child mfd-of-test-child.2: No OF node associated with this device
[0.761621] mfd-of-test-child mfd-of-test-child.3: Probing platform device: 3
[0.761899] mfd-of-test-child mfd-of-test-child.3: Using OF node: child@cccccccc
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().

The IPQ806x does not appear to have a functional multicast ethernet
address filter. This was observed as a failure to correctly receive IPv6
packets on a LAN to the all stations address. Checking the vendor driver
shows that it does not attempt to enable the multicast filter and
instead falls back to receiving all multicast packets, internally
setting ALLMULTI.
Use the new fallback support in the dwmac1000 driver to correctly
achieve the same with the mainline IPQ806x driver. Confirmed to fix IPv6
functionality on an RB3011 router.

If we don't have a hardware multicast filter available then instead of
silently failing to listen for the requested ethernet broadcast
addresses fall back to receiving all multicast packets, in a similar
fashion to other drivers with no multicast filter.

When i2c client unregisters, synchronize irq before setting
iproc_i2c->slave to NULL.
(1) disable_irq()
(2) Mask event enable bits in control reg
(3) Erase slave address (avoid further writes to rx fifo)
(4) Flush tx and rx FIFOs
(5) Clear pending event (interrupt) bits in status reg
(6) enable_irq()
(7) Set client pointer to NULL

The handling of the RXQ/TXQ size granularity design-params had two
problems: it had a 64-bit divide that didn't build on 32-bit platforms,
and it could divide by zero if the NIC supplied 0 as the value of the
design-param. Fix both by checking for 0 and for a granularity bigger
than our min-size; if the granularity <= EFX_MIN_DMAQ_SIZE then it fits
in 32 bits, so we can cast it to u32 for the divide.
