[PATCH 4.14 128/137] Revert "ARM: dts: imx7d: Invert legacy PCI irq mapping"

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Leonard Crestez <leonard.crestez@xxxxxxx>

[ Upstream commit 538d6e9d597584e80514698e24321645debde78f ]

This reverts commit 1c86c9dd82f859b474474a7fee0d5195da2c9c1d.

That commit followed the reference manual but unfortunately the imx7d
manual is incorrect.

Tested with ath9k pcie card and confirmed internally.
