Subject: [PATCH v1 0/2] PCI: ti: k3: Fix TI J721E PERST# polarity
Date: Wed,  3 Jul 2024 12:00:34 +0200	[thread overview]
Message-ID: <20240703100036.17896-1-francesco@dolcini.it> (raw)

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Fix PCIe PERST# signal polarity in TI J721E used on TI K3 machines.

PCIe PERST# needs to be de-asserted for PCIe to work, however, the driver is
doing the opposite and the device tree files are defining the signal with the
wrong polarity to cope with that. Fix both the driver and the affected DT
files.
