This patch series adds RTC (Real-Time Clock) driver support for the Rust
kernel, including the necessary infrastructure and a complete driver implementation
for the PL031 RTC.
---
v2:
- Migrate RTC driver data storage from parent device to RTC device for unified interface
- Expand AMBA bus abstractions to full driver support with enhanced functionality
- Refactor device wakeup API by moving wake IRQ setup to IRQ layer
- Simplify RTC core framework by removing multi-bus abstractions, focusing on core operations
- Optimize PL031 driver implementation and remove build assertion dependency
v1: https://lore.kernel.org/rust-for-linux/20260104060621.375...
- Add AMBA bus abstractions
- Add device wakeup support
- Add RTC core framework with multi-bus support
- Add PL031 RTC driver
