Subject: net: fsl_enetc: add i.MX95 EMDIO support
X-Git-Tag: v2025.04-rc1~41^2~4
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7dfcd0ee384eae41ec07e18d695a04d91f416548;p=pandora-u-boot.git

net: fsl_enetc: add i.MX95 EMDIO support

The verdor ID and device ID of i.MX95 EMDIO are different from LS1028A
EMDIO, so add new vendor ID and device ID to pci_device_id table to
support i.MX95 EMDIO.
