Signed-off-by: Samuel Kayode --- v3: - Address Dmitry's feedback - Drop compatible string - Remove dependency on OF - Use generic device properties - Drop unnecessary includes - Drop unnecessary initializations in probe - Always use the KEY_POWER property for onkey->keycode - Do mapping of irqs in MFD driver - Define onkey->input before interrupts are active - Drop unnecessary input_free_device since devm - Manage onkey irqs instead of the main interrupt line. - Fix integer overflow when unmasking onkey irqs in onkey_resume. v2: - Add driver for onkey --- drivers/input/misc/Kconfig | 11 +++ drivers/input/misc/Makefile | 1 + drivers/input/misc/pf1550-onkey.c | 202 ++++++++++++++++++++++++++++++++++++++ 3 files changed, 214 insertions(+) diff --git a/drivers/input/misc/Kconfig b/drivers/input/misc/Kconfig index f5496ca0c0d2bfcb7968503ccd1844ff43bbc1c0..50ae50628f4d03f54b5678dbd28e3b58f8d02f86 100644 --- a/drivers/input/misc/Kconfig +++ b/drivers/input/misc/Kconfig @@ -179,6 +179,17 @@ config INPUT_PCSPKR To compile this driver as a module, choose M here: the module will be called pcspkr. +config INPUT_PF1550_ONKEY + tristate "PF1550 Onkey support" + depends on MFD_PF1550 + help + Say Y here if you want support for PF1550 PMIC.
