* [PATCH 0/2] Add DTs for all Apple M1 (t8103) devices @ 2021-11-16 21:53 Janne Grunau 2021-11-16 21:53 ` [PATCH 1/2] dt-bindings: arm: apple: Add iMac (24-inch 2021) to Apple bindings Janne Grunau 2021-11-16 21:53 ` [PATCH 2/2] arm64: dts: apple: Add missing M1 (t8103) devices Janne Grunau 0 siblings, 2 replies; 5+ messages in thread From: Janne Grunau @ 2021-11-16 21:53 UTC (permalink / raw) To: Hector Martin, Sven Peter, Alyssa Rosenzweig, Rob Herring Cc: Mark Kettenis, linux-arm-kernel, devicetree, linux-kernel this series adds DTs for all current Apple M1 devices. Specifically it adds DTs for following devices: - MacBook Air (M1, 2020) - Macbook Pro (13-inch, M1, 2020) - iMac (24-inch, M1, 2021) With the addition of PCIe support the devices started to differ in their supported hardware. The MacBook Air and Pro do not have an ethernet and USB PCIe controllers. The 24-inch iMac has a configuration without USB ihost controller. In addtion it will help with AsahiLinux bootloader (m1n1). It started in October to refuse to load DTs that do not match the model it is running on.
