Pull ARM SoC fixes from Arnd Bergmann:
"This round of fixes has two larger changes that came in last week:
- a couple of patches all intended to finally turn on USB support on
various Amlogic SoC based boards. The respective driver were not
finalized until very late before the merge window and the DT

- a defconfig update for gemini that had repeatedly missed the cut
but that is required to actually boot any real machines with the
default build.
The rest are the usual small changes:
- a fix for a nasty build regression on the OMAP memory drivers
- a fix for a boot problem on Intel/Altera SocFPGA

We found the I2C controller count register is unreliable sometimes,
that will cause I2C to lose data. Thus we can read the data count
from 'i2c_dev->count' instead of the I2C controller count register.

i2cdev_ioctl_rdwr() allocates i2c_msg.buf using memdup_user(), which
returns ZERO_SIZE_PTR if i2c_msg.len is zero.
Currently i2cdev_ioctl_rdwr() always dereferences the buf pointer in case
of I2C_M_RD | I2C_M_RECV_LEN transfer. That causes a kernel oops in
case of zero len.
Let's check the len against zero before dereferencing buf pointer.
This issue was triggered by syzkaller.

SyS_mprotect+0x1b4/0x350
system_call+0x58/0x6c
One way to avoid this is removing the smp-call. We can ensure that the
timer always runs on one of the policy-cpus. If the timer gets
migrated to a cpu outside the policy then re-queue it back on the
policy->cpus. This way we can get rid of the smp-call which was being
used to set the pstate on the policy->cpus.

"These are two watchdog-related fixes, fix for a backlight regression
from the 4.16 cycle that unfortunately was propagated to -stable and a

allow the watchdog to allocate its resources before the PNP code
gets to them and prevents it from working correctly (Mika
Westerberg).

the WDAT one which conflicts with the RTC on that platform (Mika
Westerberg).

The block responsible of parsing the DT for the number of chip-select
lines uses an 'if/else if/else if' block. The content of the second and
third 'else if' conditions are:
1/ the actual condition to enter the sub-block and
2/ the operation to do in this sub-block.
[...]
else if (condition1_to_enter && action1() == failed)
raise_error();
else if (condition2_to_enter && action2() == failed)
raise_error();
[...]
In case of failure, the sub-block is entered and an error raised.
Otherwise, in case of success, the code would continue erroneously in
the next 'else if' statement because it did not failed (and did not
enter the first 'else if' sub-block).
The first 'else if' refers to legacy bindings while the second 'else if'
refers to new bindings. The second 'else if', which is entered
erroneously, checks for the 'reg' property, which, for old bindings,
does not mean anything because it would not be the number of CS
available, but the regular register map of almost any DT node. This
being said, the content of the 'reg' property being the register map
offset and length, it has '2' values, so the number of CS in this
situation is assumed to be '2'.
When running nand_scan_ident() with 2 CS, the core will check for an
array of chips. It will first issue a RESET and then a READ_ID. Of
course this will trigger two timeouts because there is no chip in front
of the second CS:
[ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080)
[ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280)
Indeed, this is harmless and the core will then assume there is only one
valid CS.
Fix the logic in the whole block by entering each sub-block just on the
'is legacy' condition, doing the action inside the sub-block. This way,
when the action succeeds, the whole block is left.
Furthermore, for both the old bindings and the new bindings the same
logic was applied to retrieve the number of CS lines:
using of_get_property() to get a size in bytes, converted in the actual
number of lines by dividing it per sizeof(u32) (4 bytes).
This is fine for the 'reg' property which is a list of the CS IDs but
not for the 'num-cs' property which is directly the value of the number
of CS.
Anyway, no existing DT uses another value than 'num-cs = <1>' and no
other value has ever been supported by the old driver (pxa3xx_nand.c).
Remove this condition and apply a number of 1 CS anyway, as already
described in the bindings.
Finally, the 'reg' property of a 'nand' node (with the new bindings)
gives the IDs of each CS line in use. marvell_nand.c driver first look
at the number of CS lines that are present in this property.
Better use of_property_count_elems_of_size() than dividing by 4 the size
of the number of bytes returned by of_get_property().

For ACPI support of the HiSilicon LPC driver we depend
on MFD_CORE config.
Currently the HiSi LPC Kconfig entry does not define this
dependency, so add it.
The reason for depending on MFD_CORE in the driver is
that we model the LPC host as an MFD, in that a platform
device will be created for each device on the bus.
We do this as we need to modify the resources of these
derived platform devices, something which we should not
do to the original devices created in the ACPI scan.
Details in e0aa1563f894 ("HISI LPC: Add ACPI support").

d6ed449afdb3 ("timekeeping: Make the MONOTONIC clock behave like the BOOTTIME clock")
72199320d49d ("timekeeping: Add the new CLOCK_MONOTONIC_ACTIVE clock")
As stated in the pull request for the unification of CLOCK_MONOTONIC and
CLOCK_BOOTTIME, it was clear that we might have to revert the change.
As reported by several folks systemd and other applications rely on the
documented behaviour of CLOCK_MONOTONIC on Linux and break with the above
changes. After resume daemons time out and other timeout related issues are
observed. Rafael compiled this list:
* systemd kills daemons on resume, after >WatchdogSec seconds
of suspending (Genki Sky). [Verified that that's because systemd uses
CLOCK_MONOTONIC and expects it to not include the suspend time.]
* systemd-journald misbehaves after resume:
systemd-journald[7266]: File /var/log/journal/016627c3c4784cd4812d4b7e96a34226/system.journal
corrupted or uncleanly shut down, renaming and replacing.
(Mike Galbraith).
* NetworkManager reports "networking disabled" and networking is broken
after resume 50% of the time (Pavel). [May be because of systemd.]
* MATE desktop dims the display and starts the screensaver right after
system resume (Pavel).
* Full system hang during resume (me). [May be due to systemd or NM or both.]
That happens on debian and open suse systems.
It's sad, that these problems were neither catched in -next nor by those
folks who expressed interest in this change.

The driver_override implementation is susceptible to a race condition
when different threads are reading vs storing a different driver
override. Add locking to avoid this race condition.
Cfr. commits 6265539776a0810b ("driver core: platform: fix race
condition with driver_override") and 9561475db680f714 ("PCI: Fix race
condition with driver_override").

For AMBA devices with unconfigured driver override, the
"driver_override" sysfs virtual file is empty, while it contains
"(null)" for platform and PCI devices.
Make AMBA consistent with other buses by dropping the test for a NULL
pointer.
Note that contrary to popular belief, sprintf() handles NULL pointers
fine; they are printed as "(null)".
