[GIT PULL] irqchip updates for Linux 5.11

From: Marc Zyngier
Date: Sat Dec 12 2020 - 08:57:36 EST


Hi Thomas,

Here the delivery from the irqchip department for 5.11. No new driver
for once, but an assortment of support for new SoCs (Microsemi Ocelot
derivatives, NXP SoCs), small fixes (QC PDC, TI SCI, Loongson HTPIC)
and cleanups (EZChip dead platform). We also have some preliminary
support for managed interrupts on platform devices (which also drags
in some fixes in the platform-MSI code and GICv3-ITS), and the removal
of the fasteoi IPI handler, which Valentin has proved not to be
required. Overall, a pretty quiet drop. Something must be brewing
somewhere.

Please note that while I usually base irqchip/next on -rc3 or -rc4,
I've had to pull in -rc6 this time in order avoid potential conflicts
with the fixes branch. I hope this won't cause too much trouble. If it
does, let me know and I'll rebase it.

Please pull,

M.
