调研方向
The missing PORT instance comes from regz's ATDF parser: the ATSAMD21G18A.atdf input triggers error.TodoInstanceWithMultipleRegisterGroups at the 'modes' elements around lines 4972-4979, which the warnings report as unhandled. Start by finding where that error is raised in the regz source and how it handles an instance with several register groups. Done means PORT appears in the generated peripherals list at 0x41004400 without the TODO error. The issue has no assignee, no linked pull request, and no recent answer, so the fix needs a maintainer decision first.

描述
I'm working on creating a HAL for an ATSAMD21G18A in a fork and thought I'd start with GPIOs, working towards a blinky example. However I don't see a PORT periph instance generated.
Excerpt from "Table 12-1. Peripherals Configuration Summary" in the datasheet:
| Periph Name | Base Address |
|---|---|
| ... | |
| NVMCTRL | 0x41004000 |
| PORT | 0x41004400 |
| DMAC | 0x41004800 |
| ... |
Input to regz (added .txt for GitHub): ATSAMD21G18A.atdf.txt
Output: regz_ATSAMD21G18A_zig.tar.gz
Excerpt from generated ATSAMD21G18A.zig:
pub const peripherals = struct {
// ...
pub const NVMCTRL: *volatile types.peripherals.NVMCTRL = @ptrFromInt(0x41004000);
/// Direct Memory Access Controller
pub const DMAC: *volatile types.peripherals.DMAC.DMAC = @ptrFromInt(0x41004800);
// ...
};
Actually, I just ran regz manually and noticed it is complaining:
warning(atdf): line 4972: the 'modes' isn't usually found in the 'register-group' element, this could mean unhandled ATDF behaviour or your input is malformed
warning(atdf): line 4973: the 'modes' isn't usually found in the 'register-group' element, this could mean unhandled ATDF behaviour or your input is malformed
warning(atdf): line 4978: the 'modes' isn't usually found in the 'register-group' element, this could mean unhandled ATDF behaviour or your input is malformed
warning(atdf): line 4979: the 'modes' isn't usually found in the 'register-group' element, this could mean unhandled ATDF behaviour or your input is malformed
warning(atdf): failed to instantiate module: error.TodoInstanceWithMultipleRegisterGroups
warning(atdf): failed to instantiate module: error.TodoInstanceWithMultipleRegisterGroups
I don't see an issue talking about this TODO item, so I'll still submit this.
