Subject: arm64: dts: ti: k3-j722s: Add wakeup domain peripherals specific to J722S
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6c21336acd5b2adf33ec73f43f31bd389381da5f;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: ti: k3-j722s: Add wakeup domain peripherals specific to J722S

Introduce the "k3-j722s-mcu.dtsi" file to contain wakeup domain peripherals
that are specific to J722S SoC and are not shared with AM62P.
Previously, those nodes were squatting the k3-j722s-main.dtsi file which
should contain only main domain peripherals.
