From 31cdd4420349f9ed7d2f54eded4604537cf734e2 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Tue, 19 Mar 2019 11:37:40 +0100 Subject: mt76x02: generalize some mmio beaconing functions Move some TBTT mmio functions to mt76x02_beacon.c and create new ones in order to be reused by USB pre-TBTT.
