Qualcomm Technologies, Inc. High Speed I2S Interface



* HS-I2S generic node



Required properties:



 - compatible : Should be "qcom,hsi2s"

 - number-of-interfaces : Denotes the number of HS-I2S interfaces

 - reg : Specifies the base physical address and the size of the HS-I2S

	 register space

 - reg-names : "lpa_if" - string to identify the HS-I2S base register

 - interrupts : Interrupt number used by this interface

 - clocks : Core clocks used by this interface

 - clock-names : Clock names for each core clock



* HS-I2S interface nodes



Required properties:



 - compatible : Should be "qcom,hsi2s-interface"

 - minor-number : Minor number of the character device interface

		  Should be 0 for HS0 interface

		  Should be 1 for HS1 interface

 - clocks : Interface clock used by this interface

 - clock-names : Clock name for the interface clock

 - pinctrl-names : Pinctrl state names for each pin group configuration

 - pinctrl-x : Defines pinctrl state for each pin group

 - iommus: The phandle and stream IDs for the SMMU used by this root

 - qcom,iova-mapping: Specifies the start address and size of iova space



Optional properties:



 - qcom,smmu-s1-bypass: Boolean, if present S1 bypass is enabled



Example:
