From e57722d4c3513b72957e6bb61bb67a4feb70c80f Mon Sep 17 00:00:00 2001 From: Peter Chiu Date: Fri, 20 May 2022 19:19:25 +0800 Subject: [PATCH 1120/1131] mt76: mt7915: add mt7986 and mt7916 pre-calibration Add pre-calibration for mt7986 and mt7916. It has different data size with mt7915. Group cal needs 54k and 94k for 2G + 5G and 2G + 6G, respectively. DPD cal needs 300k.
