[RESEND PATCH V4 0/4] Add TIOCM Signals support for RPMSG char devices

[Arun Kumar Neelakantam]

Glink transport support signals to exchange state notification between
local and remote side clients. Adding support to send/receive the signal
command and notify the clients through callback and POLL notification.

Changes since v3:
- Correct the TICOMGET case handling as per new rpmsg_get_signals prototype
- Update the rpmsg_get_signals function header

Changes since v2:
- Modify the rpmsg_get_signals function prototype

Changes since v1:
- Split the patches as per functional areas like core, char, glink
- Add set, clear mask for TIOCMSET
- Merge the char signal callback and POLLPRI patches

Arun Kumar Neelakantam (4):
  rpmsg: core: Add signal API support
  rpmsg: glink: Add support to handle signals command
  rpmsg: char: Add TIOCMGET/TIOCMSET ioctl support
  rpmsg: char: Add signal callback and POLLPRI support

From a general point of view it is hard to have an understanding of what this
patchset does and if it is the right solution due to a lack of context.

The cover letter and changelogs are sparse to a point where a
reviewer not familiar with the QC/Glink implementation can't offer much more
than syntactic comments.

Thanks,
Mathieu
