From: Robert Marko Date: Mon, 12 Feb 2024 11:35:58 +0000 (+0100) Subject: generic: 6.1: fixup QCA807x upstream PHY X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6497cdba09d6faa04a4f74465ed95ae21e2ff1ff;p=openwrt%2Fstaging%2Fjow.git generic: 6.1: fixup QCA807x upstream PHY Currently, we are checking whether the PHY package mode matches the individual PHY interface modes at PHY package probe time, but at that time we only know the PHY package mode and not the individual PHY interface modes as of_get_phy_mode() that populates it will only get called once the netdev to which PHY-s are attached to is being probed and thus this check will always fail and return -EINVAL. So, lets move this check to .config_init_once as at that point individual PHY interface modes should be populated.
