Subject: [PATCH v5 00/10] mhi: pci_generic: Misc improvements
Date: Mon, 14 Dec 2020 15:25:27 +0100	[thread overview]
Message-ID: <1607955937-26951-1-git-send-email-loic.poulain@linaro.org> (raw)

This series adjust some configuration values to ensure stability and
robustness of mhi pci devices (timeout, number of events, burst mode).

It also includes support for system sleep as well as a recovery procedure
that can be triggered when a PCI error is reported, either by PCI AER or by
the new health-check mechanism.

All these changes have been tested with Telit FN980m module

v2:
  - Cancel recovery work on suspend
v3:
  - enable doorbell_mode_switch for burst channel (HW)
  - Add mhi_initialize_controller helper patch
v4:
  - Delete hard reset on module unload, MHI reset is enough (Jeffrey)
  - Move soc reset support in MHI core (Jeffrey)
  - burst mode: enable doorbell_mode_switch for HW channels (Bhaumik)
  - Add diag channels
v5:
  - Remove useless call to mhi_initialize_controller in alloc_controller (hemant)
  - Add define for post reset timeout (hemant)
  - Fix static misses (hemant)

Loic Poulain (10):
  mhi: Add mhi_controller_initialize helper
  bus: mhi: core: Add device hardware reset support
  mhi: pci-generic: Increase number of hardware events
  mhi: pci_generic: Enable burst mode for hardware channels

  mhi: pci_generic: Add PCI error handlers
  mhi: pci_generic: Add health-check
  mhi: pci_generic: Increase controller timeout value
  mhi: pci_generic: Add diag channels
