dt-bindings: powerpc: Add Freescale/NXP MPC83xx SoCs

2026-03-07T10:32:26+00:00

Add a new binding for MPC83xx platforms, describing the board compatible strings used in currently existing device trees. Note that the SoC bus is called immr@... in many existing devicetrees, but this contradicts the simple-bus binding. Reviewed-by: Rob Herring (Arm) Reviewed-by: Christophe Leroy Signed-off-by: J.

dt-bindings: powerpc: Drop duplicate fsl/mpic.txt

2025-08-15T21:40:12+00:00

The chrp,open-pic binding schema already supports the "fsl,mpic" compatible. Add a couple of missing properties and support for 4 "#interrupt-cells" to the chrp,open-pic binding, so fsl/mpic.txt can be removed.

dt-bindings: gpio: Create a trivial GPIO schema

2025-07-18T08:20:06+00:00

Many simple GPIO controllers without interrupt capability have the same schema other than their compatible value. Combine all these bindings into a single schema. The criteria to be included here is must use 2 cells, have no interrupt capability, have 0 or 1 "reg" entries, and have no other resources (like clocks). Note that "ngpios" is now allowed in some cases it wasn't before and constraints on it have been dropped.

dt-bindings: interrupt-controller: Convert fsl,mpic-msi to YAML

2025-06-30T21:37:39+00:00

As part of a larger effort to bring various PowerPC-related bindings into the YAML world, this patch converts msi-pic.txt to YAML and moves it into the bindings/interrupt-controller/ directory. The conversion may necessarily be a bit hard to read because the binding is quite verbose. Signed-off-by: J.

dt-bindings: powerpc: Convert fsl/pmc.txt to YAML

2025-04-22T14:40:08+00:00

This patch rewrites pmc.txt into YAML format. Descriptive texts are expanded or shortened in a few places to better fit today's conventions. The list of compatible strings (and combinations of them) is based on existing device trees in arch/powerpc as well as compatible strings already mentioned in the plain-text version of the binding. One thing I didn't handle are soc-clk@... nodes as seen in arch/powerpc/boot/dts/fsl/pq3-power.dtsi. They are also ignored by Linux drivers. Signed-off-by: J.
