gpu: host1x: syncpt: Request syncpoints per client 2017-10-20T12:19:51+00:00 Thierry Reding treding@nvidia.com 2017-08-30T10:48:31+00:00 617dd7cc490b72345277e2666c8ed34d4f47f0da Rather than request syncpoints for a struct device *, request them for a struct host1x_client *. This is important because subsequent patches are going to break the assumption that host1x will always be the parent for devices requesting a syncpoint. It's also a more natural choice because host1x clients are really the only ones that will know how to deal with syncpoints. Note that host1x clients are always guaranteed to be children of host1x, regardless of their location in the device tree. Signed-off-by: Thierry Reding <treding@nvidia.com>
