dt-bindings: timer: nxp,sysctr-timer: Add i.MX94 support

2025-04-07T23:52:06+00:00

Add compatible string "nxp,imx94-sysctr-timer" for the i.MX94 chip, which
is backward compatible with i.MX95. Set it to fall back to
"nxp,imx95-sysctr-timer".

dt-bindings: timer: Add SiFive CLINT2

2025-03-23T09:55:43+00:00

Add compatible string and property for the SiFive CLINT v2. The SiFive
CLINT v2 is incompatible with the SiFive CLINT v0 due to differences
in their control methods.

dt-bindings: timer: exynos4210-mct: add samsung,exynos2200-mct-peris compatible

2025-03-07T16:55:59+00:00

Whilst having a new multicore timer that differs from the old designs in
functionality and registers (marked as MCTv2 in vendor kernels),
Exynos2200 also keeps an additional multicore timer connected over PERIS
that reuses the same design as older exynos socs.

Add a compatible for the legacy multicore timer of Exynos2200. Rather
than differentiating it based on the block version, mark it as the
one connected over PERIS.

dt-bindings: timer: Correct indentation and style in DTS example

2025-03-07T16:55:59+00:00

DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.

No functional changes here, but saves some comments during reviews of
new patches built on existing code.
