* msm: gsi: check channel state on timeoutSkylar Chang2017-08-10
| | | | | | | | | | | | In some cases of stopping a channel, the CH CTRL interrupt arrives late even though the channel is already stopped. This change will check the channel state after timeout occurs.

* msm: ipa3: Ring IPA MHI event ring doorbell on channel startGhanim Fodi2017-06-25
| | | | | | | | | | | Ringing IPA MHI event ring doorbell is done at MHI device during MHI channel start. This is done after the rings are allocated. The ring write pointer updated by the host is used as the doorbell value. Doorbell ringing is required in order to supply event credits to GSI H/W.
