From 49b2b5c39e10fd442b89844ae6a510a207c0c8c9 Mon Sep 17 00:00:00 2001 From: Potin Lai Date: Fri, 21 Jun 2024 17:31:41 +0800 Subject: [PATCH] dt-bindings: pinctrl: aspeed,ast2600-pinctrl: add NCSI groups In the NCSI pin table, the reference clock output pin (RMIIXRCLKO) is not needed on the management controller side. Add "NCSI" pin groups that are equivalent to the RMII pin groups, but without the RMIIXRCLKO pin.
