Subject: [PATCH v7 14/16] PCI: imx6: Add epc_features in imx6_pcie_drvdata
Date: Wed, 27 Dec 2023 13:27:25 -0500 [thread overview]
Message-ID: <20231227182727.1747435-15-Frank.Li@nxp.com> (raw)
In-Reply-To: <20231227182727.1747435-1-Frank.Li@nxp.com>
The i.MX EP exhibits variations in epc_features among different EP
configurations. This introduces the addition of epc_features in
imx6_pcie_drvdata to accommodate these differences. It's important to note
that there are no functional changes in this commit; instead, it lays the
groundwork for supporting i.MX95 EP functions.

Notes:
Change from v5 to v6
- add missed maxitems.
- add comments about reuse linux,pci-domain as controller id.
linux,pci-domain have not defined at PCI endpoint side.
Change from v1 to v3
- new patch at v3
