1Krait Processor Sub-system (KPSS) Application Clock Controller (ACC) 2 3The KPSS ACC provides clock, power domain, and reset control to a Krait CPU. 4There is one ACC register region per CPU within the KPSS remapped region as 5well as an alias register region that remaps accesses to the ACC associated 6with the CPU accessing the region. 7 8PROPERTIES 9 10- compatible: 11 Usage: required 12 Value type: <string> 13 Definition: should be one of: 14 "qcom,kpss-acc-v1" 15 "qcom,kpss-acc-v2" 16 17- reg: 18 Usage: required 19 Value type: <prop-encoded-array> 20 Definition: the first element specifies the base address and size of 21 the register region. An optional second element specifies 22 the base address and size of the alias register region. 23 24- clocks: 25 Usage: required 26 Value type: <prop-encoded-array> 27 Definition: reference to the pll parents. 28 29- clock-names: 30 Usage: required 31 Value type: <stringlist> 32 Definition: must be "pll8_vote", "pxo". 33 34- clock-output-names: 35 Usage: optional 36 Value type: <string> 37 Definition: Name of the output clock. Typically acpuX_aux where X is a 38 CPU number starting at 0. 39 40Example: 41 42 clock-controller@2088000 { 43 compatible = "qcom,kpss-acc-v2"; 44 reg = <0x02088000 0x1000>, 45 <0x02008000 0x1000>; 46 clocks = <&gcc PLL8_VOTE>, <&gcc PXO_SRC>; 47 clock-names = "pll8_vote", "pxo"; 48 clock-output-names = "acpu0_aux"; 49 };
