[RESEND 01/11] irqchip: ls-extirq: Add LS1043A, LS1088A external interrupt

[RESEND 01/11] irqchip: ls-extirq: Add LS1043A, LS1088A external interrupt

[Biwen Li]

From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>

Add an new IRQ chip declaration for LS1043A and LS1088A
- compatible "fsl,ls1043a-extirq" for LS1043A, LS1046A
- compatible "fsl,ls1088a-extirq" for LS1088A, LS208xA, LX216xA

Three things:
- This commit message doesn't describe the bit_reverse change
- Please add a cover letter
- Sending the same series again after 4 days is not OK, specially when
   the initial one was during the merge window.

Yeah, please elaborate on that, as the RM for 1043 or 1046 doesn't
mention anything about bit reversal for the scfg registers - they don't
seem to have the utter nonsense that is SCFG_SCFGREVCR, but perhaps,
instead of removing it, that has just become a hard-coded part of the IP.

Also, IANAL etc., but

>> +// Copyright 2019-2020 NXP

really? Seems to be a bit of a stretch.

At the very least, cc'ing the original author and only person to ever
touch that file would have been appreciated.

We do have an internal policy to require developer adding/updating NXP copyright on non-trivial changes.  I'm not sure if this change should be considered trivial, but adding copyright claim on a file without prior copyright claims could causing confusion like in this case.  One potential solution is to add a more specific description on the NXP change together with the copyright claim.  But maybe an easier solution is to add Rasmus your Copyright claim first if you are ok with it.

Leo

The copyright exists implicitly, and doesn't require a copyright claim
in the file itself. Please talk to your legal department.

That's for Rasmus to decide whether he wants to add such a claim,
given that it exists implicitly. Adding copyright claims for any
odd change you make isn't acceptable either (your changes are already
unambiguously identified in git).

For the time being, I'm not taking any NXP patch carrying additional
copyright update until this is clarified.

The copyright exists implicitly, and doesn't require a copyright claim
in the file itself. Please talk to your legal department.

That's for Rasmus to decide whether he wants to add such a claim,
given that it exists implicitly. Adding copyright claims for any
odd change you make isn't acceptable either (your changes are already
unambiguously identified in git).
