The MSI interrupts are especially useful for the guest machine execution. The wired interrupts usually trap to the hypervisor and then are relayed to the actual interrupt. The MSI interrupts can be directly fed into the interrupt controller. Adding a new OF compat string (qcom,hidma-1.1) and ACPI string (QCOM8062) to distinguish newer HW from the older ones. v6: * rebase 4.9 kernel v5: http://www.spinics.net/lists/arm-kernel/msg537014.html * dmaengine: qcom_hidma: add MSI support for interrupts ** Return MSI interrupts before calling platform_msi_domain_free_irqs. Also cleanup MSI interrupts on the error path. ** Free the legacy IRQ only if MSI is disabled * add dmaengine: qcom_hidma: break completion processing on error in order to break the completions if an error is observed while servicing completed work. * drop dmaengine: qcom_hidma: make error and success path common as the success path assumes that we'll get the number of notifications for the jobs queued. This is not true under error conditions. * simplify dmaengine: qcom_hidma: protect common data structures. We just need to protect the TRE processed offset.
