Subject: [PATCH v3 0/6] Add chrdev and name query support for GLINK
Date: Thu, 26 Apr 2018 15:58:59 -0700 [thread overview]
Message-ID: <1524783545-21951-1-git-send-email-clew@codeaurora.org> (raw)
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. Create a label property that will help userspace clients
distinguish between the different GLINK links. 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 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
