[PATCH v1 1/2] arm64: dts: ti: Mark PCIe PERST# polarity active low in DT

Francesco Dolcini francesco at dolcini.it
Wed Jul 3 03:00:35 PDT 2024


From: Emanuele Ghidoli <emanuele.ghidoli at toradex.com>

As the name indicates, PERST# is active low. Fix the DT description to
match the HW behaviour.
