* msm-pacman - The MSM Peripheral Access Control Manager



Required Properties:



 - compatible:	"qcom,msm-pacman"



Aliases:



  An alias is required to properly map the i2c/SPI bus driver to a Qualcomm

  Universal Peripheral (QUP) ID. The alias is of the form 'qup<n>', where

  <n> is an integer specifying the QUP ID.



Example:



	aliases {

		i2c2 = &i2c_2;

		qup2 = &ic2_2;

	};



	qcom,msm-pacman {

		compatible = "qcom,msm-pacman";
