Subject: [PATCH v2 0/8] Amazon's Annapurna Labs DT-based PCIe host controller driver
Date: Thu, 18 Jul 2019 12:45:23 +0300 [thread overview]
Message-ID: <20190718094531.21423-1-jonnyc@amazon.com> (raw)
This series adds support for Amazon's Annapurna Labs DT-based PCIe host
controller driver.
Additionally, it adds 3 quirks (ACS, VPD and MSI-X) and 2 generic DWC patches.
Regarding the 2nd DWC patch (PCI flags support), do you think this should
be done in the context of a host-bridge driver at all (as opposed to PCI
system-wide code)?
Changes since v1:
- Added comment regarding 0x0031 being used as a dev_id for non root-port devices as well
- Fixed different message/comment/print wordings
- Added panic stacktrace to commit message of MSI-x quirk patch
- Changed to pci_warn() instead of dev_warn()
- Added unit_address after node_name in dt-binding
- Updated Kconfig help description
- Used GENMASK and FIELD_PREP/GET where appropriate
- Removed leftover field from struct al_pcie and moved all ptrs to
the beginning
- Re-wrapped function definitions and invocations to use fewer lines
- Change %p to %px in dbg prints in rd/wr_conf() functions
- Removed validation that the port is configured to RC mode (as this is
added generically in PATCH 7/8)
- Removed unnecessary variable initializations
- Swtiched to %pR for printing resources
