Subject: [PATCH 0/2] arch: arm64: dts: apple: Disable unused PCIe ports
Date: Tue, 14 Feb 2023 15:07:21 +0100 [thread overview]
Message-ID: <20230214-apple_dts_pcie_disable_unused-v1-0-5ea0d3ddcde3@jannau.net> (raw)
The t8103 and t600x device trees deleted unused PCIe ports. This was
probably done to replicate Apple's device tree which doesn't has nodes
for most unused hardware.
A more accurate description of the hardware is to disable unused
hardware.
This was discovered during the review of the t8112 device trees in
https://lore.kernel.org/asahi/1ea2107a-bb86-8c22-0bbc-82c453ab08ce@linaro.org/
