Subject: arm64: dts: apple: t8103: Disable unused PCIe ports
X-Git-Tag: v6.1.28~418
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f977dbefeaea05a198b0537052ebcfd3aa62f7a8;p=users%2Fdwmw2%2Flinux.git

arm64: dts: apple: t8103: Disable unused PCIe ports

[ Upstream commit a0189fdfb73dac856b8fa9b9f9581e5099c9391f ]

The PCIe ports are unused (without devices) so disable them instead of
removing them.
