1 Qualcomm SPMI Controller (PMIC Arbiter)
3 The SPMI PMIC Arbiter is found on the Snapdragon 800 Series. It is an SPMI
4 controller with wrapping arbitration logic to allow for multiple on-chip
5 devices to control a single SPMI master.
7 The PMIC Arbiter can also act as an interrupt controller, providing interrupts
10 See spmi.txt for the generic SPMI controller binding requirements for child
13 See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
14 generic interrupt controller binding documentation.
17 - compatible : should be "qcom,spmi-pmic-arb".
18 - reg-names : must contain:
19 "core" - core registers
20 "intr" - interrupt controller registers
21 "cnfg" - configuration registers
22 - reg : address + size pairs describing the PMIC arb register sets; order must
23 correspond with the order of entries in reg-names
24 - #address-cells : must be set to 2
25 - #size-cells : must be set to 0
26 - qcom,ee : indicates the active Execution Environment identifier (0-5)
27 - qcom,channel : which of the PMIC Arb provided channels to use for accesses (0-5)
28 - interrupts : interrupt list for the PMIC Arb controller, must contain a
29 single interrupt entry for the peripheral interrupt
30 - interrupt-names : corresponding interrupt names for the interrupts
31 listed in the 'interrupts' property, must contain:
32 "periph_irq" - summary interrupt for PMIC peripherals
33 - interrupt-controller : boolean indicator that the PMIC arbiter is an interrupt controller
34 - #interrupt-cells : must be set to 4. Interrupts are specified as a 4-tuple:
35 cell 1: slave ID for the requested interrupt (0-15)
36 cell 2: peripheral ID for requested interrupt (0-255)
37 cell 3: the requested peripheral interrupt (0-7)
38 cell 4: interrupt flags indicating level-sense information, as defined in
39 dt-bindings/interrupt-controller/irq.h
