SoC specific 19 dt-binding should be included to the device tree descriptor. For example 20 Alphascale ASM9260: 21 22 #include <dt-bindings/clock/alphascale,asm9260.h> 23 24 This binding contains two types of clock providers: 25 26 _AHB_ - AHB gate; 27 _SYS_ - adjustable clock source. Not all peripheral have _SYS_ clock provider. 28 29 All clock specific details can be found in the SoC documentation. 30 31properties: 32 compatible: 33 const: alphascale,asm9260-clock-controller 34 35 reg: 36 maxItems: 1 37 38 '#clock-cells': 39 const: 1 40 41 clocks: 42 maxItems: 1 43 44required: 45 - compatible 46 - reg 47 - '#clock-cells' 48 49additionalProperties: false 50
