From: Chin-Ting Kuo Date: Fri, 10 Oct 2025 08:03:13 +0000 (+0800) Subject: dt-bindings: watchdog: aspeed,ast2400-wdt: Add support for AST2700 X-Git-Tag: v6.19-rc1~80^2~23 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b3bc229b54e780fe02a41ec65a0cb06acf7ac1d9;p=thirdparty%2Fkernel%2Flinux.git dt-bindings: watchdog: aspeed,ast2400-wdt: Add support for AST2700 Add support for the AST2700 SoC in the ASPEED watchdog device tree bindings. This includes: - Adding "aspeed,ast2700-wdt" to the compatible string list. - Extending the "aspeed,reset-mask" property description for AST2700. - Defining AST2700-specific reset mask bits in aspeed-wdt.h, covering RESET1 to RESET5.
