From bf0602f9c8afaf1110e79be4f1370bf63aaf3623 Mon Sep 17 00:00:00 2001 From: Bryan Berg Date: Sat, 18 May 2024 16:29:28 -0700 Subject: [PATCH] ipq806x: ap3935: Use rgmii-id mode for LAN1 Fix issue with LAN1 interface on ap3935 devices, where the LAN 1interface won't come up after boot unless the bootloader has initialized the network stack. Use of `fixed-link` in the prior code kept the driver from clobbering PHY settings, but now that the driver supports rgmii-id phy-mode, we can just use that.
