It came to my attention that the file "whatisRCU.txt" does not
manage to actually ever spell out what is RCU.
This might not be an issue for a lot of people, but we have to
assume the consumers of these documents are starting from ground
zero; otherwise they'd not be reading the docs.

- Stefan provides updates to the BCM2835 RNG Device Tree binding and
Device Tree node by adding its missing interrupt line.
- Rafal switches the Luxul XWC-1000 and the D-Link DIR-885L to the new
partitions syntax which allows specifying a partition parser
- Rafal also updates a bunch of BCM5301X Device Tree source files to a
more standard SPDX tag and dual GPL 2.0 and MIT. This is a follow-up
to this discussion with Greg:
https://lkml.org/lkml/2018/4/28/179
- Dan adds support for two Luxul devices: XAP-1610 (based on BCM47094)
and XWR-3150 V1 (similar to XWR-3100)
- Stefan provides a set of updates to the BCM283x Device Tree sources to
support the Raspberry Pi 3 B+ for both the ARM and ARM64 kernels. He
adds the required nodes for the LAN7515 USB Ethernet, Cypress CYW43455
BT/WiFi combo chip. Stefan also provides a few fixes for the PWM pin
assignment for RPi 3B and Zero/Zero W. Finally, Stefan adds the
missing GPIOs for controlling additional peripherals now that support
for the RPi 3 GPIO expander has landed

The Allwinner R40 SoC has the EMAC controller supported by dwmac-sun8i.
It is named "GMAC", while EMAC refers to the 10/100 Mbps Ethernet
controller supported by sun4i-emac. The controller is the same, but
the R40 has the glue layer controls in the clock control unit (CCU),
with a reduced RX delay chain, and no TX delay chain.
This patch adds the R40 specific bits to the dwmac-sun8i binding.

The syscon property is used to point to the device that holds the glue
layer control register known as the "EMAC (or GMAC) clock register".
We do not need to explicitly list what compatible strings are needed, as
this information is readily available in the user manuals. Also the
"syscon" device type is more of an implementation detail. There are many
ways to access a register not in a device's address range, the syscon
interface being the most generic and unrestricted one.
Simplify the description so that it says what it is supposed to
describe.

The clock delay chains found in the glue layer for dwmac-sun8i are only
used with RGMII PHYs. They are not intended for non-RGMII PHYs, such as
MII external PHYs or the internal PHY. Also, a recent SoC has a smaller
range of possible values for the delay chain.
This patch reformats the delay chain section of the device tree binding
to make it clear that the delay chains only apply to RGMII PHYs, and
make it easier to add the R40-specific bits later.

Currently the firmware loader only exposes one silent path for querying
optional firmware, and that is firmware_request_direct(). This function
also disables the sysfs fallback mechanism, which might not always be the
desired behaviour [0].
This patch introduces a variations of request_firmware() that enable the
caller to disable the undesired warning messages but enables the sysfs
fallback mechanism. This is equivalent to adding FW_OPT_NO_WARN to the
old behaviour.

This driver is a logical device which provides an
interface between the hypervisor and a management
partition. This interface is like a message
passing interface. This management partition
is intended to provide an alternative to HMC-based
system management.
VMC enables the Management LPAR to provide basic
logical partition functions:
- Logical Partition Configuration
- Boot, start, and stop actions for individual
partitions
- Display of partition status
- Management of virtual Ethernet
- Management of virtual Storage
- Basic system management
This driver is to be used for the POWER Virtual
Management Channel Virtual Adapter on the PowerPC
platform. It provides a character device which
allows for both request/response and async message
support through the /dev/ibmvmc node.

The driver prints pcsr twice: the first time it uses specifier %px to
print hexadecimal pcsr value and the second time uses specifier %pS for
output kernel symbols.
As suggested by Kees, using %pS should be sufficient and %px isn't
necessary; the reason is if the pcsr is a kernel space address, we can
easily get to know the code line from %pS format, on the other hand, if
the pcsr value doesn't fall into kernel space range (e.g. if the CPU is
stuck in firmware), %pS also gives out pcsr hexadecimal value.
So this commit removes useless %px and update section "Output format"
in the document for alignment between the code and document.
