soc: qcom: apr: make code more reuseable

2022-12-31T12:13:57+00:00

[ Upstream commit 99139b80c1b3d73026ed8be2de42c52e2976ab64 ] APR and other packet routers like GPR are pretty much same and interact with other drivers in similar way. Ex: GPR ports can be considered as APR services, only difference is they are allocated dynamically. Other difference is packet layout, which should not matter with the apis abstracted. Apart from this the rest of the functionality is pretty much identical across APR and GPR. Make the apr code more reusable by abstracting it service level, rather than device level so that we do not need to write new drivers for other new packet routers like GPR. This patch is in preparation to add GPR support to this driver.

soc: qcom: apr: Add avs/audio tracking functionality

2020-03-15T05:38:50+00:00

Use PDR helper functions to track the protection domains that the apr services are dependent upon on SDM845 SoC, specifically the "avs/audio" service running on ADSP Q6.

soc: qcom: Add APR bus driver

2018-05-11T03:13:26+00:00

This patch adds support to APR bus (Asynchronous Packet Router) driver. APR driver is made as a bus driver so that the apr devices can added removed more dynamically depending on the state of the services on the dsp. APR is used for communication between application processor and QDSP to use services on QDSP like Audio and others.
