From: Tobias Schramm Date: Sun, 4 Feb 2024 14:55:01 +0000 (+0100) Subject: realtek: 5.15: rtl930x: introduce SerDes mode macros X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9fe2412e62f894546cf99f03ca2b48231e83376a;p=openwrt%2Fstaging%2F981213.git realtek: 5.15: rtl930x: introduce SerDes mode macros Previously SerDes modes were specified ad-hoc in hex. Introduce and use macros for SerDes modes.
