[PATCH v3 2/3] arm64: dts: apple: t8103: Fix PCIe #PERST polarity
flat view
STALE1766d
LANDED
From: Marc Zyngier <maz@kernel.org>
Date: 2021-11-23 18:06:48
Also in:
linux-pci, lkml
Subsystem:
arm/apple machine support, the rest · Maintainers:
Sven Peter, Janne Grunau, Linus Torvalds
Landed in mainline as 5b970dfcfee9 on 2021-12-07.
As the name indicates, #PERST is active low. So fix the DT description
to match the HW behaviour.
Fixes: ff2a8d91d80c ("arm64: apple: Add PCIe node")
