These are based on Linux next with the following pending patch applied: "Input: omap4-keypad - switch to use managed resources" Regards, Tony Changes since v4: - Rebase on Dmitry's devm patch - Fix up kernel test robot warnings and mismerge of pm_ops when I rebased from v5.10 to Linux next - Split up the patches further as suggested by Dmitry Changes since v3: - Use PM runtime to check the last pressed key is not stuck - Simplify probe with devm Changes since v2: - Drop bogus level change, that already comes from device tree - Scan keyboard in two phases and simplify using a bitmask - Use mod_delayed_work and cancel_delayed_work_sync for the quirk Tony Lindgren (5): Input: omap4-keypad - disable unused long interrupts Input: omap4-keypad - scan keys in two phases and simplify with bitmask Input: omap4-keypad - move rest of key scanning to a separate function Input: omap4-keypad - use PM runtime autosuspend Input: omap4-keypad - implement errata check for lost key-up events drivers/input/keyboard/omap4-keypad.c | 172 ++++++++++++++++++++------ 1 file changed, 132 insertions(+), 40 deletions(-)
