Subject: [PATCH 5/5] riscv: dts: spacemit: improve RTL8211F PHY configuration on K3 Pico-ITX board
Date: Sat, 20 Jun 2026 08:22:06 +0200	[thread overview]
Message-ID: <20260620062238.3199108-6-aurelien@aurel32.net> (raw)
In-Reply-To: <20260620062238.3199108-1-aurelien@aurel32.net>

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.
