Subject: [PATCH] clk: qcom: Make oxili GDSC parent of oxili_cx GDSC
Date: Wed, 23 Sep 2015 12:09:22 -0700 [thread overview]
Message-ID: <1443035362-10914-1-git-send-email-sboyd@codeaurora.org> (raw)
The oxili_cx GDSC is inside the power domain of the oxili GDSC.
Add the dependency so that the CX domain can properly power up.
