From 0503aec22c1483d02b2d8bbd8594c5b9713294b8 Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Thu, 10 Jan 2019 09:32:09 +0530 Subject: soc: qcom: rpmhpd: Mark mx as a parent for cx Specify the active + sleep and active-only MX power domains as the parents of the corresponding CX power domains. This will ensure that performance state requests on CX automatically generate equivalent requests on MX power domains. This is used to enforce a requirement that exists for various hardware blocks on SDM845 that MX performance state >= CX performance state for a given operating frequency.
