rust: allow `clippy::as_underscore` in the generated bindings2026-09-06T23:06:23+00:00John Hubbardjhubbard@nvidia.com2026-09-06T21:58:22+00:00urn:sha1:2ac74c6db40adaa29c50cbb281ae9a6f63de18e1
A CLIPPY=1 build emitted about 15000 `as _` conversion warnings, all of
them in bindgen's generated output and none in hand-written code.
[ The lint messages look like:
error: using `as _` conversion
--> rust/bindings/bindings_generated.rs:18947:9
|
18947 | self._bitfield_1.get_const::<0usize, 16u8>() as u32 as _

= note: `-D clippy::as-underscore` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(clippy::as_underscore)]`
- Miguel ]
bindgen 0.73 returns each bitfield read through a trailing `as _`, and
0.72 returns it through a transmute, which the lint ignores. The
bindings and uapi crates allow `clippy::all` over the generated code.
That group does not cover `clippy::as_underscore`, a restriction lint.
Allow `clippy::as_underscore` by name in the bindings and uapi crates.

rust: io: register: unify handling of register with/without bitfields2026-09-06T11:39:49+00:00Gary Guogary@garyguo.net2026-09-01T16:50:40+00:00urn:sha1:a12f711dc53c1ca1d7ff4184e1609182174de87b
Move the `FixedRegister` from a property of register to become a property
of type. Name the new trait `FixedIoLoc` indicating if I/O location of a
type is unique for a specific base. Thus, bitfields become just a special
case of this (where type is unique because we're generating it in the
register macro), and expose feature to registers without inline bitfield
definition with the `#[unique]` attribute.

rust: io: register: remove `Register` trait and cleanup macro2026-09-06T11:39:49+00:00Gary Guogary@garyguo.net2026-09-01T16:50:39+00:00urn:sha1:a8ab43a1089e289b58d303a1c10d0f81284087e7
With the removal of relative registers, there are only two type of
registers left, fixed register and register arrays. There is not much
benefit in having a common super trait for them anymore, thus remove it,
and cleanup the macro rules associated with it.

rust: io: register: remove relative registers2026-09-06T11:39:49+00:00Gary Guogary@garyguo.net2026-09-01T16:50:38+00:00urn:sha1:631adefcac893728c278f4bd2c9634cfe3f35482
Relative registers can be better served by projection to subregion instead
of ad-hoc handling in register macro. Projection composes better (e.g. it
natively allows relative registers of relative registers without needing
additional support).
Remove relative register support, and update the documentation to
demonstrate how projection and subregions can be used to achieve this
instead.
