v5 - Added OF dependency in Kconfig, added extra fault flag read to ensure that
if a fault exists and it is not a artifact, fixed LED class label
This adds the devicetree bindings for the LM3692x
I2C LED string driver.

Add ETH_RESET_AP to reset the application processor(s) inside the NIC
interface.
Current ETH_RESET_MGMT supports a management processor inside this NIC.
This is typically used for remote NIC management purposes.
Application processors exist inside some SmartNICs to run various
applications inside
Add support to reset appplication processors inside SmartNICs by
defining new ETH_RESET_AP bit.
And use new ETH_RESET_AP bit in bnxt ethernet driver.

Amazon EFS provides an NFSv4.1 filesystem which appears to use
(close to) full length (128 byte) file handles.
This causes the handle reported by name_to_handle_at() to exceed
MAX_HANDLE_SZ, resulting in
EOVERFLOW if 128 bytes were requested, or

There is a common methods signature form used over all the NTB API
like functions naming scheme, arguments names and order, etc.
Recently added NTB messaging API IO callbacks were named a bit
different so should be renamed to be in compliance with the rest
of the API.

Since Switchtec patch there has been a new topology added to
the NTB API. It's called NTB_TOPO_SWITCH and dedicated for
PCIe switch chips. Even though topo field isn't used within the
IDT driver much, lets set it for the sake of unification.

Multi-port interface is now available in ntb_tool driver. According
to the new NTB API, there might be more than two devices connected over
NTB. It means each device can have multiple freely enumerated ports.
Each port got index assigned by NTB hardware driver. This test is

DB interface of ntb_tool driver hasn't been changed much, but
db_valid_mask DebugFS file has still been added. In this case
it's much better to test all valid DB bits instead of using
the predefined mask, which may be incorrect in general.
