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 staging-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 e94b3c608a2a886758da87dc5bb383e5eddce666 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 6 Oct 2020 18:17:34 -0700 Subject: dt-bindings: iio: sx9310: Add various settings as DT properties We need to set various bits in the hardware registers for this device to operate properly depending on how it is installed. Add a handful of DT properties to configure these things.
