From: Álvaro Fernández Rojas Date: Fri, 24 Mar 2023 09:05:23 +0000 (+0100) Subject: kernel: add more dsa b53 pending patches X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b88ae628cbc924aa9403e208a000143bc7a4647b;p=openwrt%2Fstaging%2Fnbd.git kernel: add more dsa b53 pending patches These patches have now received a positive review upstream, so let's add them to pending patches. 776-net-dsa-b53-mmap-add-phy-ops.patch: This is mostly bmips/bcm63xx-specific to get external switches working without hanging the device when accessing certain registers. 777-net-dsa-b53-mdio-add-support-for-BCM53134: This adds support for BCM53134 switch on DSA B53, so any target using DSA B53 can benefit from it. Also fix sercomm-h500-s external switch IMP port phy-mode.
