The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 676748389f5db74e7d28f9d630eebd75cb8a11b4 Mon Sep 17 00:00:00 2001 From: Sven Peter Date: Sat, 26 Feb 2022 13:59:12 +0100 Subject: usb: typec: tipd: Forward plug orientation to typec subsystem In order to bring up the USB3 PHY on the Apple M1 we need to know the orientation of the Type-C cable. Extract it from the status register and forward it to the typec subsystem.
