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 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 Arun Kumar Neelakantam (2): rpmsg: glink: unregister rpmsg device during endpoint destroy rpmsg: Add compat ioctl for rpmsg char driver Chris Lew (7): dt-bindings: soc: qcom: Add label for GLINK bindings rpmsg: glink: Store edge name for glink device rpmsg: glink: Use complete_all for open states rpmsg: Guard against null endpoint ops in destroy rpmsg: glink: Add support for rpmsg glink chrdev rpmsg: glink: Expose rpmsg name attr for glink rpmsg: glink: Remove chunk size word align warning .../devicetree/bindings/soc/qcom/qcom,glink.txt | 5 ++ drivers/rpmsg/qcom_glink_native.c | 88 ++++++++++++++++++++-- drivers/rpmsg/rpmsg_char.c | 2 + drivers/rpmsg/rpmsg_core.c | 2 +- 4 files changed, 90 insertions(+), 7 deletions(-)
