From: Andrew Jeffery Date: Fri, 9 Jan 2026 06:35:18 +0000 (+1030) Subject: dt-bindings: mfd: Document smp-memram subnode for aspeed,ast2x00-scu X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=30e312bb1f410459e6dd0e742f3665e1f205f0f9;p=thirdparty%2Flinux.git dt-bindings: mfd: Document smp-memram subnode for aspeed,ast2x00-scu The platform initialisation code for the AST2600 implements the custom SMP bringup protocol, and searches for the relevant compatible. As a consequence, define the requisite node and the compatible string, which in-turn tidies up the dtb check results.
