| |
Add support for the GLINK rpmsg transport to register a rpmsg chrdev. This will create the rpmsg_ctrl nodes for userspace clients to open rpmsg epts. The rpmsg chrdev allocation is done by allocating a local channel which also allocates an ept. We need to add some guards against edge cases for this chrdev because it will never fully open.
Changes since v5: - Re-orange the completion_done code
Changes since v4: - Resending by removing approved patches
Changes since v3: - Change to device_add_group for rpmsg name attr - Add patch to unregister the rpmsg device - Add patch to support compat ioctl for rpmsg char driver
Changes since v2: - Revert change to make glink attribute table const
Changes since v1: - Add explanation to dt-bindings commit message - Add patch complete_all the open_req/ack variables - Add patch to prevent null pointer dereference in chrdev channel release - Change chrdev allocation to use glink channel allocation - Change glink attr struct to const
