mfd: sec: Drop now unused struct sec_pmic_dev::irq_data

2026-01-20T15:37:48+00:00

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.

mfd: sec: Change device_type to int

2025-05-23T07:48:44+00:00

Now that sec-i2c doesn't match device type by pointer casting anymore, we can switch the device type from unsigned long to int easily. This saves a few bytes in struct sec_pmic_dev due to member alignment.

mfd: sec: Split into core and transport (i2c) drivers

2025-05-23T07:48:23+00:00

As a preparation for adding support for Samsung's S2MPG10, which is connected via SPEEDY / ACPM rather than I2C, split out (move) all I2C-specific driver code into its own kernel module, sec-i2c, and make the existing sec-core module be just the transport-agnostic core driver kernel module. At the same time, update all defconfigs that reference the old kconfig symbol name. While at it, also update file header comments and module description(s) to drop references to 'mfd', and update comments to be C-style, not C++.

mfd: sec: Move private internal API to internal header

2025-05-23T07:48:22+00:00

sec_irq_init() is an internal API for the core driver, and doesn't belong into the public header. Due to an upcoming split of the driver into a core and i2c driver, we'll also be adding more internal APIs, which again shouldn't be in the public header. Move it into a new internal include.
