Subject: [PATCH v3 0/3] Add sysfs entry to EDL mode
Date: Mon, 15 Apr 2024 16:49:02 +0800
Message-Id: <1713170945-44640-1-git-send-email-quic_qianyu@quicinc.com>
Precedence: bulk

Add EDL sysfs entry for mhi controller that provides edl_trigger callback.
Add mhi_pci_generic_edl_trigger for qualcomm sdx55,sdx65 and sdx75 as
edl_trigger callback.

v2->v3:
1. Update Documentation/ABI/stable/sysfs-bus-mhi with description of
   force_edl sysfs entry.

2. Add comments about edl_trigger callback in mhi_controller struct.

3. Follow reverse christmas tree in mhi_pci_generic_edl_trigger.

4. Add a new API in MHI to allow controller to get CHDB address and avoid
   duplicating the definition of CHDBOFF.

v1->v2:
1. Move all process needed by qualcomm sdx55,sdx65,sdx75 to enter EDL into
   mhi_pci_generic_edl_trigger() as the callback to edl_trigger.

2. MHI stack creates EDL sysfs entry to invoke edl_trigger callback so
   that devices need different mechanism to enter EDL can provide its own
   edl_trigger callabck .

Qiang Yu (3):
  bus: mhi: host: Add sysfs entry to force device to enter EDL
  bus: mhi: host: Add a new API for getting channel doorbell address
  bus: mhi: host: pci_generic: Add edl callback to enter EDL
