9961bf1876 mfd: max14577: Use module_init() instead of subsys_initcall()
The driver's init function is called at subsys init call level but the
dependencies provided by the driver are looked up by drivers that have
probe deferral support, so manual ordering of init calls isn't needed.

9e3d5c996b mfd: hi655x-pmic: Rename some interrupt macro names
Currently the hi655x-pmic driver has names for interrupt mask
values, but not for the interrupt numbers themselves.

So to allow for interrupt numbers to have sane names, rename
the mask values with the _MASK postfix and use the existing
names as the interrupt name

417e06bb3f mfd: hi655x-pmic: Fixup issue with un-acked interrupts
While trying to get the powerkey to function, I found when
pressing the key, I would get infinitely repeating interrupts.

After digging around a bit, it seems we didn't set the ack_base
value for the regmap irqchip logic, so nothing was acking the
interrupt.

This patch adds the ack_base, which seems to make things work.

1f2c39726f mfd: arizona: Check if AOD interrupts are pending before dispatching
Previously the arizona_irq_thread implementation would call
handle_nested_irqs() to handle AOD interrupts without checking if any
were actually pending. The kernel will see these as spurious IRQs and
will eventually disable the IRQ.

This patch ensures we only launch the nested handler if there are AOD
interrupts pending in the codec.

9835f1b70b mfd: qcom_rpm: Fix offset error for msm8660
The RPM in MSM8660/APQ8060 has different offsets to the selector
ACK and request context ACK registers. Make all these register
offsets part of the per-SoC data and assign the right values.

The bug was found by verifying backwards to the vendor tree in
the out-of-tree files <mach/rpm-[8660|8064|8960]>: all were using
offsets 3,11,15,23 and a select size of 4, except the MSM8660/APQ8060
which was using offsets 3,11,19,27 and a select size of 7.

All other platforms apart from msm8660 were affected by reading
excess registers, since 7 was hardcoded as the number of select
words, this patch makes also this part dynamic so we only write/read
as many select words as the platform actually use.

Symptoms of this bug when using msm8660: the first RPM transaction
would work, but the next would stall or raise an error since the
previous transaction was not properly ACKed as the ACK words were
read at the wrong offset.

3df140d11c mfd: max77620: Mask/unmask interrupt before/after servicing it
The programming guidelines of the MAX77620 for servicing interrupt is:
1. When interrupt occurs from PMIC, mask the PMIC interrupt by
   setting GLBLM.
2. Read IRQTOP and service the interrupt.
3. Once all interrupts has been checked and serviced, the interrupt
   service routine un-masks the hardware interrupt line by clearing
   GLBLM.

Add the pre and post interrupt service handler for mask and unmask the
global interrupt mask bit (for step 1 and 3) as callback from regmap-irq.

The kernel expects the power_off function to not return, and if it does
it panics. Add a slight delay after the i2c write which turns off power
through the PMIC, to give capacitors etc. some time to drain.

Without this the kernel lives on long enough after the poweroff to
print the following on the serial console on my Mele A1000G quad:

[  248.583588] reboot: Power down
[  248.600490] Kernel pa

drivers/net/dsa/b53/b53_mmap.c:83:11: error: 'hi' may be used uninitialized in this function [-Werror=maybe-uninitialized]
   *val = ((u64)hi << 16) | lo;

I have seen the warning before and at the time thought I had fixed
it with 55e7f6abe1 ("dsa: b53: fix big-endian register access"),
however it now came back in a different randconfig build that happens
to have different inlining decisions in the compiler.

The mistake that gcc makes here is that it thinks the second call to
readl() might fail because the address 'reg + 4' is not a multiple
of four despite having knowing that 'reg' itself is a multiple of four.

By open-coding the two reads without the redundant alignment check,
we can avoid the warning and produce slightly better object code, but
get slightly longer source code instead.

6025530738 backlight: lp855x: Add enable regulator
The LP8556 datasheet describes an EN/VDDIO input, which serves "both as
a chip enable and as a power supply reference for PWM, SDA, and SCL
inputs." The LP8556 that I'm testing doesn't respond properly if I try
to talk I2C to it too quickly after enabling VDDIO, and the LP8555
datasheet mentions a t_RESPONSE delay of up to 1 millisecond.

Support this EN/VDDIO by adding a regulator property to the binding;
enabling this regulator at probe time; and sleeping for 1 to 2ms, if the
EN/VDDIO regulator was provided.

Saeed Mahameed says:

====================
Mellanox 100G mlx5 fixes#2 for 4.7-rc

The following series provides one-liners fixes for mlx5 driver plus one
medium patch to reorganize ethtool counters reporting.

Highlights:
	- Added MODIFY_FLOW_TABLE to command strings table
	- Add ConnectX-5 PCIe 4.0 to list of supported devices
	- Rename ASYNC_EVENTS enum
	- Enable BlueFlame only when supported by device
	- Avoid adding same vxlan port twice
	- Report the correct number of PFC counters
	- Reorganize ethtool reported counters and remove duplications

bfe6d8d1d4 net/mlx5e: Reorganize ethtool statistics
Categorize and reorganize ethtool statistics counters by renaming to
"rx_*" and "tx_*" and removing redundant and duplicated counters, this
way they are easier to grasp and more user friendly.

ed80ec4c17 net/mlx5e: Fix number of PFC counters reported to ethtool
Number of PFC counters used to count only number of priorities with PFC
enabled, but each priority has more than one counter, hence the need to
multiply it by the number of PFC counters per priority.

ba34a65324 drm/i915: Avoid early timeout during AUX transfers
Since wait_for_atomic doesn't re-check the wait-for condition after
expiry of the timeout it can fail when called from non-atomic context
even if the condition is set correctly before the expiry. Fix this by
using the non-atomic wait_for instead.

Due to the relatively long 10ms timeout, probably this didn't cause any
real problems, but fix it in any case for consistency.
