Subject: RE: [PATCH 0/6] Add IMX8M Mini PCI support
Date: Fri, 30 Jul 2021 01:27:57 +0000	[thread overview]
Message-ID: <VI1PR04MB58533AF76EA4DFD8AD6CDA158CEC9@VI1PR04MB5853.eurprd04.prod.outlook.com> (raw)
In-Reply-To: <36070609-9f1f-00c8-ccf5-8ed7877b29da@pengutronix.de>

Hi Tim:
Just as Ahmad mentioned, Lucas had issue one patch-set to support i.MX8MM PCIe.
Some comments in the review cycle.
- One separate PHY driver should be used for i.MX8MM PCIe driver.
- Schema file should be used I think, otherwise the .txt file in the dt-binding.

I'm preparing one patch-set, but it's relied on the yaml file exchanges and power-domain changes(block control and so on).
Up to now, I only walking on the first step, trying to exchange the dt-binding files to schema yaml file.

Best Regards
Richard Zhu
