For "fixed" PCI devices, such as chips directly soldered
on the main board (ethernet, Wi-Fi, serial ports, etc.),
it is possible to find an ACPI enumeration.
This allows to add useful properties to these devices.
Just for an example: the property "gpio-line-names" can be
added to the pins of a GPIO expander on the PCI bus.
In order to find the ACPI name of a PCI device, it's necessary
to disassemble the BIOS ACPI tables (in particular the DSDT)
and also to analyze the PCI bus topology of the board.
This patch, with a practical example, show how to do this.

A new module option, implicit_fb, is added to specify the driver
looking for the implicit feedback sync. This can be useful for a
device that could be working better in the implicit feed back mode and
user wants to test it quickly. When this works, we can add the quirk
entry easily.

The MIPI I3C HCI (Host Controller Interface) specification defines
a common software driver interface to support compliant MIPI I3C
host controller hardware implementations from multiple vendors.
All that is needed is an I/O area and an interrupt signal;. The hardware
is self-advertising wrt its implementor and implemented capabilities so
there is currently no details that the driver can't figure out on its own.

This is a somewhat unusual device, in that it effectively does
spi offload. That means that it doesn't act as a full SPI
master, but supports some functionality. As such it supports
a subset of specific SPI ADCs. There is potential for a future
clash in bindings, but as these are simple devices hopefully that
will not occur.
One addition to this from testing it against existing dts files
was to add a resets property.
This is specified in arch/arm/boot/dts/r8a7791.dtsi
If it's the dtsi that is wrong and not the binding doc, then
we can fix that instead.
