rpmsg: qcom_smd: Make qcom_smd_unregister_edge() return void

2023-04-06T03:58:32+00:00

This function returned zero unconditionally. Convert it to return no value instead. This makes it more obvious what happens in the callers. One caller is converted to return zero explicitly. The only other caller (smd_subdev_stop() in drivers/remoteproc/qcom_common.c) already ignored the return value before.

rpmsg: glink: smem: Wrap driver context

2023-02-14T16:19:38+00:00

The Glink SMEM driver allocates a struct device and hangs two devres-allocated pipe objects thereon. To facilitate the move of interrupt and mailbox handling to the driver, introduce a wrapper object capturing the device, glink reference and remote processor id. The type of the remoteproc reference is updated, as these are specifically targeting the SMEM implementation.

rpmsg: glink: Guard qcom_glink_ssr_notify() with correct config

2021-01-06T04:22:07+00:00

The qcom_glink_ssr_notify() function doesn't relate to the SMEM specific GLINK config, but the common RPMSG_QCOM_GLINK config. Update the guard to properly reflect this.

rpmsg: Turn name service into a stand alone driver

2020-11-24T16:11:59+00:00

Make the RPMSG name service announcement a stand alone driver so that it can be reused by other subsystems. It is also the first step in making the functionatlity transport independent, i.e that is not tied to virtIO.

2020-05-07T18:04:38+00:00

In all but the very special case of a system with _only_ glink_rpm, GLINK is dependent on glink_ssr, so move it to rpmsg and combine it with qcom_glink_native in the new qcom_glink kernel module.

Rather than carrying a special purpose blocking notifier for glink_ssr in remoteproc's qcom_common.c, move it into glink_ssr so allow wider reuse of the common one. The rpmsg glink header file is used in preparation for the next patch.
