Annotated Snippet
The TI palmas family current members :-
twl6035 (palmas)
twl6037 (palmas)
tps65913 (palmas)
tps65914 (palmas)
tps659038
tps65917
Required properties:
- compatible : Should be from the list
ti,twl6035
ti,twl6036
ti,twl6037
ti,tps65913
ti,tps65914
ti,tps80036
ti,tps659038
ti,tps65917
and also the generic series names
ti,palmas
- interrupt-controller : palmas has its own internal IRQs
- #interrupt-cells : should be set to 2 for IRQ number and flags
The first cell is the IRQ number.
The second cell is the flags, encoded as the trigger masks from
Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
Optional properties:
ti,mux-padX : set the pad register X (1-2) to the correct muxing for the
hardware, if not set will use muxing in OTP.
Example:
palmas {
compatible = "ti,twl6035", "ti,palmas";
reg = <0x48>
interrupt-parent = <&intc>;
interrupt-controller;
#interrupt-cells = <2>;
ti,mux-pad1 = <0>;
ti,mux-pad2 = <0>;
#address-cells = <1>;
#size-cells = <0>;
pmic {
compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
....
};
}
Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
