[PATCH 00/21] i.MX6, DesignWare PCI improvements

From: Andrey Smirnov
Date: Fri Dec 21 2018 - 02:27:46 EST


This is the series containing various small improvements that I made
while reading the code and researching commit history of pci-imx6.c
and pcie-designware*.c files. All changes are optional, so commits
that don't seem like an improvement can be easily dropped. Hopefully
each patch is self-explanatory.

I tested this series on i.MX6Q, i.MX7D and i.MX8MQ.

Feedback is welcome!
