Subject: [v2 PATCH] clk: rockchip: mark rk3399 hdcp_noc and vio_noc as critical
Date: Tue, 9 Aug 2016 11:02:33 -0700 [thread overview]
Message-ID: <1470765753-11619-1-git-send-email-zyw@rock-chips.com> (raw)
Fix incorrect rk3399 aclk_vio gating bit, it should be 0, not 10. With
this modification, the aclk_vio_noc should be put into critical list,
since it is required by VOP.
And the Type-C DP need these clocks: aclk_hdcp_noc, hclk_hdcp_noc,
pclk_hdcp_noc. Mark them as critical to avoid someone close them.
