From: Josua Mayer Date: Tue, 17 May 2022 08:54:29 +0000 (+0300) Subject: dt-bindings: net: adin: document phy clock output properties X-Git-Tag: v5.19-rc1~159^2~67^2~2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1f77204e11f8b9e5d77d65197a03b702c50ea29b;p=thirdparty%2Fkernel%2Flinux.git dt-bindings: net: adin: document phy clock output properties The ADIN1300 supports generating certain clocks on its GP_CLK pin, as well as providing the reference clock on CLK25_REF. Add DT properties to configure both pins. Technically the phy also supports a recovered 125MHz clock for synchronous ethernet. However SyncE should be configured dynamically at runtime, so it is explicitly omitted in this binding.
