This module enables IPA Modem to IPA  APQ communication using

MHI Prime.



Required properties:

- compatible:		Must be "qcom,ipa-mpm".

- qcom,mhi-chdb-base:	MHI channel doorbell base address in MMIO space.

- qcom,mhi-erdb-base:	MHI event doorbell base address in MMIO space.



Optional:

- qcom,iova-mapping:	Start address and size of the carved IOVA space

				dedicated for MHI control structures

				(such as transfer rings, event rings, doorbells).

				If not present, SMMU S1 is considered to be in bypass mode.



Example:

	ipa_mpm: qcom,ipa-mpm {

		compatible = "qcom,ipa-mpm";

		qcom,mhi-chdb-base = <0x40300300>;

		qcom,mhi-erdb-base = <0x40300700>;

		qcom,iova-mapping = <0x10000000 0x1FFFFFFF>;
