  "message": "ast10x0: add I3C peripheral driver (port of aspeed-rust i3c)\n\nPort the AST1060 I3C controller/target driver from aspeed-rust\n(src/i3c @ ce3b567) into the ast10x0_peripherals crate, mirroring the\nexisting I2C port and following the pac-design-patterns conventions.\n\nDriver (peripherals/i3c/): ccc, config, constants, controller, error,\nhardware, ibi, mod, types. hal_impl is folded into controller as\ninherent methods (proposed_traits is unavailable in openprot and\nembedded-hal has no I3C trait).\n\nDesign-pattern conformance:\n- Confined-`unsafe` MMIO facade: raw `*const` register pointers, a single\n  `unsafe fn new`, private `\u0026\u0027static` derefs, `!Sync`; no unsafe or PAC\n  types leak above the facade.\n- Cooperative-yield bounded poll: an injected `Y: FnMut(u32)` yield\n  closure replaces embedded-hal DelayNs, type-erased at the poll loops.\n- Borrow-arbitrated exclusivity for per-call state; the global IBI/IRQ\n  plane is kept (documented delta) since an ISR cannot borrow a\n  stack-owned device.\n\nNotable deltas: drop the Logger generic and the `#[no_mangle]` ISR\nsymbol exports (kernel owns the vector and calls dispatch_i3c_irq);\nheapless 0.9 SPSC with edition-2024 `addr_of_mut!`; reachable\ntransfer/clock paths hardened to be panic-free (no_panics_test) without\nchanging success-path behavior.\n\nAlso: add scu pinctrl groups (PINCTRL_I3C0..3 / PINCTRL_HVI3C0..3, the\nHV groups clearing the conflicting LV pad bits); wire critical-section\nand cortex-m `critical-section-single-core` into the crate universe; add\ni3c_init and i3c_irq tests, the latter a faithful controller/target IBI\npair mirroring aspeed-rust tests-hw on I3C2 HV.\n\nSee target/ast10x0/peripherals/i3c/plans/goal.md for the behavioral\nparity plan, authority pin, and deltas ledger.\n\nSigned-off-by: Steven Lee \u003csteven_lee@aspeedtech.com\u003e\nCo-Authored-By: Claude Opus 4.8 (1M context) \u003cnoreply@anthropic.com\u003e\n",
