rpmsg: glink: Remove chunk size word align warning

2018-09-01T21:00:43Z

It is possible for the chunk sizes coming from the non RPM remote procs to not be word aligned. Remove the alignment warning and continue to read from the FIFO so execution is not stalled. Signed-off-by: Chris Lew Signed-off-by: Arun Kumar Neelakantam Signed-off-by: Bjorn Andersson

rpmsg: glink: Store edge name for glink device

rpmsg: glink: Use spinlock in tx path

2018-03-20T02:52:54Z

Switch the tx_lock to a spinlock we allow clients to use rpmsg_trysend() from atomic context. In order to allow clients to sleep while waiting for space in the FIFO we release the lock temporarily around the delay; which should be replaced by sending a READ_NOTIF and waiting for the remote to signal us that space has been made available.
