Subject: dt-bindings: remoteproc: qcom,msm8916-mss-pil: Add MSM8226
X-Git-Tag: v6.15-rc1~104^2~23
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=01730659e7c58bd88a88af0086125ab073dc56b8;p=thirdparty%2Flinux.git

dt-bindings: remoteproc: qcom,msm8916-mss-pil: Add MSM8226

Add support for external power block headswitch (BHS) registers.
Similarly to MSM8974 also MSM8226 has the mx voltage rail exposed as
regulator and only cx voltage rail as power domain.
