bus: mhi: host: pci_generic: Add generic edl_trigger to allow devices to enter EDL mode (2024-04-25 20:25:45 +0530)
----------------------------------------------------------------
MHI Host
========
- Added a new API mhi_power_down_keep_dev() to not destroy the struct dev
associated with the MHI channels during MHI power down. This is useful in
scenarios such as system suspend/hibernation where the probability of
channels coming back is very high. So the PM maintainer suggested not to
destroy the struct dev in those cases.
This API is introduced for fixing the failure reported in the ath11k driver
during resume from system suspend.
NOTE: Due to the API dependency, the patch adding the API is pushed to an
immutable branch (mhi-immutable) and merged into both mhi and ath trees. But
the merge commit is not visible in mhi tree due to git being smart with
'fast-forward'.
- Added an optional sysfs entry to force the MHI devices to enter the Emergency
Download (EDL) mode to download the firmware from host.
- Added EDL mode support for Qcom SDX75/65/55 modems as per the MHI spec v1.2,
Chapter 13.2. This involves writing a cookie to the EDL doorbell registers and
then triggering the device reset from host.
