Subject: [PATCH] clk: qcom: Leave mmss noc on for 8998
Date: Thu, 13 Dec 2018 09:59:30 -0700 [thread overview]
Message-ID: <1544720370-11598-1-git-send-email-jhugo@codeaurora.org> (raw)
Similar to other qcom targets, gcc_mmss_noc_cfg_ahb_clk should not be
disabled. Any mmss access depends on this clock, and its been observed
that enabling mmssnoc_axi_rpm_clk with rpmcc results in an implicit
access to mmss and will crash the system if gcc_mmss_noc_cfg_ahb_clk is
disabled.
