Extend the rtc-isl12022 driver with alarm IRQ support. Signed-off-by: Esben Haabendal <esben@xxxxxxxxxx> --- Changes in v2: - Various coding style changes. - Remove const keyword from auto variable declaration. - Use u8 type instead of uint8_t. - Fixed bad return value in isl12022_rtc_read_alarm() error handling. - Change variable type from int to unsigned int for variable given to regmap_read(). - Drop unneeded variable initialization (ret) in isl12022_rtc_set_alarm(). - Extend use of DWA0 variable to avoid false alarm trigger also when disabling alarm. - Clarify the use of !! operator in isl12022_rtc_alarm_irq_enable(). - Change isl12022_setup_irq() prototype to avoid the need for storing struct i2c_client in struct isl12022. - Use dev_err_probe() where appropriate. - Change dev_err messages reporting problems with register access into dev_dbg. - Renamed ISL12022_ALARM_SECTION to ISL12022_ALARM for better use of horizontal space. - Leave FOBATB bit untouched. - Link to v1: https://lore.kernel.org/r/20240910-rtc-isl12022-alarm-irq-v1-0-d875cedc997f@xxxxxxxxxx --- Esben Haabendal (3): rtc: isl12022: Prepare for extending rtc device drvdata rtc: isl12022: Add alarm support rtc: isl12022: Replace uint8_t types with u8 drivers/rtc/rtc-isl12022.c | 269 ++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 253 insertions(+), 16 deletions(-) --- base-commit: da3ea35007d0af457a0afc87e84fddaebc4e0b63 change-id: 20240910-rtc-isl12022-alarm-irq-197ef2350c3e Best regards, -- Esben Haabendal <esben@xxxxxxxxxx>
