2016-06-21spcom: add spcom_is_sp_subsystem_link_upAmir Samuelov
Add implementation of spcom_is_sp_subsystem_link_up() kernel API. Remove Load App API declaration, as it is not supported for kernel drivers. Change-Id: I76a43a04d454d1f25a640831f43b51dbb7e75943 Signed-off-by: Amir Samuelov <amirs@codeaurora.org>
2016-06-16soc: qcom: msm_glink_pkt: Set transport field for deviceChris Lew
When smd_trans is registered at bootup and the transport field is null, glink_pkt gets a link up notification early. Use the requested transport to register for the link up notification of the edge.

2016-06-15spcom: increase max ion buffers per channelAmir Samuelov
The number of ION buffer that can be locked per channel should be at least the number of channels. The Load App request, via the SKP channel, uses an ION buffer that is locked for application swapping by the remote SPSS.

2016-06-08soc: qcom: msm_glink_pkt: Register and wait for link up notificationArun Kumar Neelakantam
The user space clients sometimes open the device before the underlying transport available which results in open error and cause multiple re-tries from the clients. This leads to excessive logging of open error messages. Register for link state notification and block the client open until link available or user define timer expires.
