From: Jonas Jelonek Date: Sat, 25 Oct 2025 14:36:03 +0000 (+0000) Subject: realtek: phy: rtl930x: drop SerDes code X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=f578ed0dc99f04aa369b18a29b29971ef57ea4b2;p=openwrt%2Fopenwrt.git realtek: phy: rtl930x: drop SerDes code Drop the now unused SerDes code for RTL930X from rtl83xx-phy driver as the SerDes is completely managed by the PCS driver. This marks a breaking point because RTL930X SerDes is no longer treated as a regular PHY device.
