I would\nexpect them all to go via the MFD tree. Alternatively, they could be\napplied individually to the respective kernel trees during multiple\nkernel release cycles, but that seems a needless complication and\ndelay.\n\nSigned-off-by: André Draszik <andre.draszik@linaro.org>\n---\nChanges in v2:\n- rebase on top of https://lore.kernel.org/r/20251114-s2mpg10-chained-irq-v1-1-34ddfa49c4cd@linaro.org\n- return struct regmap_irq_chip_data * in sec_irq_init() (Lee)\n- collect tags\n- Link to v1: https://lore.kernel.org/r/20251114-s5m-alarm-v1-0-c9b3bebae65f@linaro.org\n\n---\nAndré Draszik (3):\n mfd: sec: add rtc alarm IRQ as platform device resource\n rtc: s5m: query platform device IRQ resource for alarm IRQ\n mfd: sec: drop now unused struct sec_pmic_dev::irq_data\n\n drivers/mfd/sec-common.c | 45 ++++++++++++++++++++--------\n drivers/mfd/sec-core.h | 2 +-\n drivers/mfd/sec-irq.c | 63 ++++++++++++++++++----------------------\n drivers/rtc/rtc-s5m.c | 21 +++++---------\n include/linux/mfd/samsung/core.h | 1 -\n 5 files changed, 71 insertions(+), 61 deletions(-)\n---\nbase-commit: 9ad5de6d54f306b2bbf7ceb27e67a60c58a71224\nchange-id: 20251114-s5m-alarm-3de705ea53ce\n\nBest regards," }
