Subject: [PATCH 1/2] bus: mhi: core: add SBL state callback
|
|
|
|
Add support for SBL state callback in MHI core.
|
|
|
|
It is required for ath11k MHI devices in order to be able to set QRTR
|
|
instance ID in the SBL state so that QRTR instance ID-s dont conflict in
|
|
case of multiple PCI/MHI cards or AHB + PCI/MHI card.
|
|
Setting QRTR instance ID is only possible in SBL state and there is
|
|
currently no way to ensure that we are in that state, so provide a
|
|
callback that the controller can trigger off.
