Loic improved the MHI PCI generic controller by adding support for DIAG channel,
PCI error handling, suspend/recovery/resume, and health check. Loic also added
support for resetting the MHI device as per the MHI specification. This includes
writing to a specific register for default cases and looking for controller
specific callback when provided.
Along with this Loic, also added a new API which gets the number for free TREs
(Transfer Ring Elements) from the MHI core. The client drivers can make use of
this API and the current consumer is the "mhi-net" driver. For taking both the
"mhi-net" driver change and the API change, we created "mhi-net-immutable"
branch for this patch and merged the same into net-next and mhi-next.
Carl added a patch which lets the controller driver to pass the custom IRQ
flags for BHI and MHI event interrupts to the MHI core. The current consumer of
this feature is the ath11k MHI controller driver. For taking both the changes,
we created "mhi-ath11k-immutable" branch for this patch and merged into
ath11k-next and mhi-next.
Finally, Loic cleaned up the MHI queue APIs and fixed the shared MSI vector
support.
