Subject: [PATCH v5 0/3] Add sysfs entry to EDL mode
Date: Wed, 24 Apr 2024 11:21:52 +0800	[thread overview]
Message-ID: <1713928915-18229-1-git-send-email-quic_qianyu@quicinc.com> (raw)

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.

v4->v5:
1. Add a blank line before the #endif in patch[2/3].

2. Add reviewed-by tag.

v3->v4:
1. Modify some comments, commit message and sysfs entry description.

2. Add error cleanups if get channel doorbell offset fail.

3. s/force_edl/trigger_edl

4. s/mhi_get_channel_doorbell/mhi_get_channel_doorbell_offset

5. Use mhi_get_channel_doorbell_offset in mhi_init_mmio()

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.
