Subject: [RFC PATCH v11 net-next 02/10] dt-bindings: net: dsa: dt bindings for microchip lan937x
Date: Fri, 25 Mar 2022 22:23:33 +0530 [thread overview]
Message-ID: <20220325165341.791013-3-prasanna.vengateshan@microchip.com> (raw)
In-Reply-To: <20220325165341.791013-1-prasanna.vengateshan@microchip.com>
Documentation in .yaml format and updates to the MAINTAINERS
Also 'make dt_binding_check' is passed.
RGMII internal delay values for the mac is retrieved from
rx-internal-delay-ps & tx-internal-delay-ps as per the feedback from
v3 patch series.
https://lore.kernel.org/netdev/20210802121550.gqgbipqdvp5x76ii@skbuf/
It supports only the delay value of 0ns and 2ns.
