Subject: [PATCH v4 0/4] PCIE support for i.MX8MQ
Date: Fri,  4 Jan 2019 08:53:31 -0800
Message-ID: <> (raw)


This series contains changes I made in order to enable support of PCIE
IP block on i.MX8MQ SoCs.

Changes since [v3]:

 - Based on feedback from NXP, DIRECT_SPEED_CHANGE quirk was expanded
   to cover both i.MX7 and i.MX8MQ

 - Code setting device type in GPR12 moved to a standalone function

 - Explicit "fsl,controller-id" binding was dropped, replaced by using
   controller physical address to determine logical ID

 - Dropped Reviewed-by from Lucas for patch 4/4 due to the change
   above (haven't heard explicit "yea" for it from him)

Changes since [v2], [fixes]:

 - Incorporated [patch] introducing drvdata

 - i.MX6 PHY operation gating converted to a single patch and to use a
   dedicated flag instead of doing explicit variant check

 - Kconfig entry changed to use ARM64 && ARCH_MXC

 - Dropped FALLTHROUGH annotations

Changes since [v1]:

 - Driver changed to use single "fsl,controller-id" property to
   distinguish between two intances of PCIE IP block

 - All code pertaining to L1SS was dropped to simplify the patch

 - Documented additions to DT bindings

Feedback is welcome!
