The netdev-FAQ document has grown over the years to the point
where finding information in it is somewhat challenging.
The length of the questions prevents readers from locating
content that's relevant at a glance.
Convert to a more standard documentation format with sections
and sub-sections rather than questions and answers.
The content edits are limited to what's necessary to change
the format, and very minor clarifications.

Subsequent changes will reformat the doc away from FAQ.
To make that more readable perform the pure section moves now.

Pull more devicetree updates from Rob Herring:
"This is mostly a treewide clean-up from Krzysztof. There's also a
couple of fixes and things that fell thru the cracks.
I must say this has been a nice merge window without bindings dumped
in at the last minute introducing warnings.
Summary:
- Treewide dropping of redundant 'binding' or 'schema' from schema
titles. This will be followed up with a automated check to catch
these.
- Re-sort vendor-prefies
- Convert GPIO based watchdog to schema
- Handle all the variations for clocks, resets, power domains in i.MX
PCIe binding
- Document missing 'power-domains' property in mxsfb
- Fix error with path references in Tegra XUSB example
- Honor CONFIG_CMDLINE* even without /chosen node"

The i.MX6 and i.MX7D does not use block controller to toggle PCIe
reset, hence the PCIe DT description contains three reset entries
on these older SoCs. Add this exception into the binding document.

The i.MX SoCs have various power domain configurations routed into
the PCIe IP. MX6SX is the only one which contains 2 domains and also
uses power-domain-names. MX6QDL do not use any domains. All the rest
uses one domain and does not use power-domain-names anymore.
Document all those configurations in the DT binding document.

Binutils 2.23 was released in 2012. Almost 10 years old.
We already require GCC 5.1, released in 2015.
Bump the binutils version to 2.25, which was released some months
before GCC 5.1.
With this applied, some subsystems can start to clean up code.
Examples:
arch/arm/Kconfig.assembler
arch/mips/vdso/Kconfig
arch/powerpc/Makefile
arch/x86/Kconfig.assembler

Add dma-channel-mask property in Tegra GPCDMA document.
The property would help to specify the channels to be used in
kernel and reserve few for the firmware. This was previously
achieved by limiting the channel number to 31 in the driver.
This is wrong and does not align with the hardware. Correct
this and set the max interrupts to 32.

In current code, the following sysfs attributes are exposed to user to
show or update the values:
max_read_buffers (max_tokens)
read_buffer_limit (token_limit)
group/read_buffers_allowed (group/tokens_allowed)
group/read_buffers_reserved (group/tokens_reserved)
group/use_read_buffer_limit (group/use_token_limit)
>From Intel IAA spec [1], Intel IAA does not support Read Buffer
allocation control. So these sysfs attributes should not be supported on
IAA device.
Fix this issue by making these sysfs attributes invisible through
is_visible() filter when the device is IAA.
Add description in the ABI documentation to mention that these
attributes are not visible when the device does not support Read Buffer
allocation control.

The drivers are transitioning from matching against lists of specific
compatible strings to matching against smaller lists of more generic
compatible strings. Use the SDM845 compatible string as a fallback in
the schema to support this change.

A100 features an updated DPHY, which moves PLL control inside the DPHY
register space. (Previously PLL-MIPI was controlled from the CCU. This
does not affect the "clocks" property because the link between PLL-MIPI
and the DPHY was never represented in the devicetree.) It also requires
a modified analog power-on sequence. Finally, the new DPHY adds support
for operating as an LVDS PHY. D1 uses this same variant.

The sun6i DPHY can generate several interrupts, mostly for reporting
error conditions, but also for detecting BTA and UPLS sequences.
Document this capability in order to accurately describe the hardware.
The DPHY has no interrupt number provided in the vendor documentation
because its interrupt line is shared with the DSI controller.
A trivial interrupt handler was used to verify that interrupts were in
fact generated by the DPHY and not the DSI controller.
