From e0c1145f4c8ea0515b32e0b9620412528a4312b1 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Tue, 23 Jun 2026 22:43:49 +0200 Subject: [PATCH] riscv: dts: spacemit: improve RTL8211F PHY configuration on K3 Pico-ITX board Vendor kernel enabled ALDPS (Advanced Link Down Power Saving) on the RTL8211F PHY to save power when link down. Vendor kernel also disabled the 125MHz clkout clock signal, and indeed the schematics confirms that it only goes to a test point (TP14), so let's do the same.
