-Qualcomm SPMI Controller (PMIC Arbiter)
-
-The SPMI PMIC Arbiter is found on Snapdragon chipsets. It is an SPMI
-controller with wrapping arbitration logic to allow for multiple on-chip
-devices to control a single SPMI master.
-
-The PMIC Arbiter can also act as an interrupt controller, providing interrupts
-to slave devices.
-
-See Documentation/devicetree/bindings/spmi/spmi.yaml for the generic SPMI
-controller binding requirements for child nodes.
-
-See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
-generic interrupt controller binding documentation.
-
-Required properties:
-- compatible : should be "qcom,spmi-pmic-arb".
-- reg-names : must contain:
- "core" - core registers
- "intr" - interrupt controller registers
- "cnfg" - configuration registers
- Registers used only for V2 PMIC Arbiter:
- "chnls" - tx-channel per virtual slave registers.
- "obsrvr" - rx-channel (called observer) per virtual slave registers.
-
-- reg : address + size pairs describing the PMIC arb register sets; order must
- correspond with the order of entries in reg-names
-- #address-cells : must be set to 2
-- #size-cells : must be set to 0
-- qcom,ee : indicates the active Execution Environment identifier (0-5)
-- qcom,channel : which of the PMIC Arb provided channels to use for accesses (0-5)
-- interrupts : interrupt list for the PMIC Arb controller, must contain a
- single interrupt entry for the peripheral interrupt
-- interrupt-names : corresponding interrupt names for the interrupts
- listed in the 'interrupts' property, must contain:
- "periph_irq" - summary interrupt for PMIC peripherals
-- interrupt-controller : boolean indicator that the PMIC arbiter is an interrupt controller
-- #interrupt-cells : must be set to 4. Interrupts are specified as a 4-tuple:
- cell 1: slave ID for the requested interrupt (0-15)
- cell 2: peripheral ID for requested interrupt (0-255)
- cell 3: the requested peripheral interrupt (0-7)
- cell 4: interrupt flags indicating level-sense information, as defined in
- dt-bindings/interrupt-controller/irq.h
-
-Example:
-
- spmi {
- compatible = "qcom,spmi-pmic-arb";
- reg-names = "core", "intr", "cnfg";
- reg = <0xfc4cf000 0x1000>,
- <0xfc4cb000 0x1000>,
- <0xfc4ca000 0x1000>;
-
- interrupt-names = "periph_irq";

- interrupt-controller;
- #interrupt-cells = <4>;
