From: Evan Lloyd <evan.lloyd@arm.com>

This series of patches corrects a problem detected on the ARM Juno
platform that is actually generic (at least to ARM GIC platforms).
The HardwareInterrupt protocol had no means of handling characteristics
like Edge/Level triggered and polarity.

A new HardwareInterrupt2 protocol (provided by Ard) is added,
and code changed to utilise the new capabilities.

The code is available for examination on Github at:
    https://github.com/EvanLloyd/tianocore/tree/376_irqtype_v1

Ard Biesheuvel (3):
  EmbeddedPkg: introduce HardwareInterrupt2 protocol
  ArmPkg/ArmGicDxe: expose HardwareInterrupt2 protocol
  ArmPkg/GenericWatchdogDxe: Set Watchdog interrupt type

Girish Pathak (1):
  ArmPkg:Provide GetTriggerType/SetTriggerType functions

I'd like to make something clear here.  We found a problem and solicited opinion.
Ard very helpfully proposed a solution, complete with a rapid response example patch.
However, it was code he wrote quickly to propose a solution - and I imagine he didn't expect it to go directly into the code line.
We submitted his patches as sent, because we felt we should not take credit for his excellent work.
So any problems here are our fault, not Ard's - and he didn't get to review things before submission.
I'll tidy things up, and try again.

Evan

Hi Evan,

No, this is all fine - you've submitted his originals as "From: Ard
Biesheuvel", which retains him as original author of 1-3.
It's completely up to Ard whether he wants to get involved or not at
this point. The v1 of the series was sent out by you, so I expect any
v2 to come from you as well :)

This may be a slightly unusual situation for the edk2-devel mailing
list, but it's just business as usual on many Linux kernel lists.

Regards,

Leif
