Tested on Apple M3 MacBook Air (T8122): - All 4 GPIO controllers probe successfully with lockdep enabled. - The "Invalid wait context" warning no longer occurs. - The regmap KUnit suite passes and lockdep remains enabled. --- Changes in v2: - Link to v1: https://lore.kernel.org/r/20260925-regcache-lifecycle-submit-v1-1-83b75ca79d96@gmail.com - Make Maple cache teardown IRQ-safe. - Fix debugfs ordering during cache teardown and reinitialization. - Rebase onto the latest upstream tree. --- Michael Reeves (2): regmap: Remove debugfs before cache teardown regmap: Drop map lock during cache init and exit drivers/base/regmap/regcache-maple.c | 5 +++-- drivers/base/regmap/regcache.c | 6 ------ drivers/base/regmap/regmap-debugfs.c | 1 + drivers/base/regmap/regmap.c | 15 +++++++++------ 4 files changed, 13 insertions(+), 14 deletions(-) --- base-commit: 6addb4f385570ebc11c4eb499a4f1c149f313e84 change-id: 20260925-regcache-lifecycle-submit-74f366be0fbc Best regards, -- Michael Reeves
