Subject: [PATCH v7 13/13] arm64: dts: cix: Enable PCIe on the Orion O6 board

From: Hans Zhang <hans.zhang@...tech.com>

Add PCIe RC support on Orion O6 board.

Signed-off-by: Hans Zhang <hans.zhang@...tech.com>

Dear Krzysztof,

Due to the fact that the GPIO, PINCTRL and other modules of our platform are
not yet ready for upstream. Attributes that PCIe depends on, such as reset-gpios
and pinctrl*, have not been added for the time being. It will be added gradually
in the future.

The following are Arnd's previous comments. We can go to upsteam separately.
