Subject: [PATCH V3 00/10] dmaengine: qcom_hidma: add MSI interrupt support
Date: Thu, 15 Sep 2016 13:22:36 -0400 [thread overview]
Message-ID: <1473960166-30155-1-git-send-email-okaya@codeaurora.org> (raw)
The new version of the HW supports MSI interrupts instead of wired
interrupts. 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.
v3:
* day 0 fix for when ACPI is not compiled in
v2:
https://patchwork.kernel.org/patch/9326399/
* Documentation update for DT bindings
* Rebased to slave-next
* Dropped dmaengine: qcom_hidma: eliminate processed variables. Replaced it
with dmaengine: qcom_hidma: protect common data structures
v1:
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-July/444167.html
* initial implementation
