[PATCH v5 0/4] PCIE support for i.MX8MQ

[Andrey Smirnov]

Everyone:

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

Changes since [v4]:

 - Collected Reviewed-by from Lucas

 - Replaced ((ARM || ARM64) && COMPILE_TEST) with COMPILE_TEST as per
   suggestion from Rob

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!

Thanks,
Andrey Smirnov
