[PATCH v3 0/3] Samsung mfd/rtc driver alarm IRQ simplification

[PATCH v3 0/3] Samsung mfd/rtc driver alarm IRQ simplification

[André Draszik]

Hi,

With the attached patches the Samsung s5m RTC driver is simplified a
little bit with regards to alarm IRQ acquisition.

The end result is that instead of having a list of IRQ numbers for each
variant (and a BUILD_BUG_ON() to ensure consistency), the RTC driver
queries the 'alarm' platform resource from the parent (mfd cell).

Additionally, we can drop a now-useless field from runtime data,
reducing memory consumption slightly.

The attached patches must be applied in-order as patch 2 without 1 will
fail at runtime, and patch 3 without 2 will fail at build time. I would
expect them all to go via the MFD tree. Alternatively, they could be
applied individually to the respective kernel trees during multiple
kernel release cycles, but that seems a needless complication and
delay.

Changes in v2:
- rebase on top of https://lore.kernel.org/r/20251114-s2mpg10-chained-irq-v1-1-34ddfa49c4cd@linaro.org

[PATCH v3 1/3] mfd: sec: add rtc alarm IRQ as platform device resource

[André Draszik]

By adding the RTC alarm IRQ to the MFD cell as a resource, the child
driver (rtc) can simply query that IRQ, instead of having a lookup
table itself.

This change therefore allows the child driver to be simplified with
regards to determining the alarm IRQ.

[PATCH v3 2/3] rtc: s5m: query platform device IRQ resource for alarm IRQ

[André Draszik]

The core driver now exposes the alarm IRQ as a resource, so we can drop
the lookup from here to simplify the code and make adding support for
additional variants easier in this driver.

[PATCH v3 3/3] mfd: sec: drop now unused struct sec_pmic_dev::irq_data

[André Draszik]

This was used only to allow the s5m RTC driver to deal with the alarm
IRQ. That driver now uses a different approach to acquire that IRQ, and
::irq_data doesn't need to be kept around anymore.
