Late reset controller changes for v5.0

This adds missing deassert functionality to the ARC HSDK reset driver,
fixes some indentation and grammar issues in the kernel docs, adds a
helper to count the number of resets on a device for the non-DT case
as well, adds an early reset driver for SoCFPGA and simple reset driver
support for Stratix10, and generalizes the uniphier USB3 glue layer
reset to also cover AHCI.

mvebu fixes for 5.0

They are all device tree fixes which also worth being in stable:

 - Reserve PSCI area on Armada 7K/8K preventing the kernel accessing
   this area and crashing while doing it.

 - Use correct PCIe reset signal on MACCHIATOBin  (Armada 8040 based)

 - Fix polarity of GPIO fan line D-Link DNS NASes(kikwood based)

2019-01-13T06:03:18+00:00

Fixes for the Integrator:
- Handle failed allocations in the IM/PC bus attachment.
- Use struct_size() for allocation.

ARM: integrator: impd1: use struct_size() in devm_kzalloc()

2019-01-11T12:33:00+00:00

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

gpio: pl061: handle failed allocations

2019-01-10T14:54:50+00:00

devm_kzalloc(), devm_kstrdup() and devm_kasprintf() all can
fail internal allocation and return NULL. Using any of the assigned
objects without checking is not safe. As this is early in the boot
phase and these allocations really should not fail, any failure here
is probably an indication of a more serious issue so it makes little
sense to try and rollback the previous allocated resources or try to
continue;  but rather the probe function is simply exited with -ENOMEM.

ARM: dts: kirkwood: Fix polarity of GPIO fan lines

2019-01-10T11:23:47+00:00

These two lines are active high, not active low. The bug was
found when we changed the kernel to respect the polarity defined
in the device tree.

ARM: dts: da850-lcdk: Correct the audio codec regulators

2019-01-10T08:02:51+00:00

Add the board level fixed regulators for 3.3V and 1.8V which is used to
power - among other things - the tlv320aic3106 codec.

Apart from removing the following warning during boot:
tlv320aic3x-codec 0-0018: Invalid supply voltage(s) AVDD: -22, DVDD: -22

With the correct voltages the driver can select correct OCMV value to
reduce pop noise.
