Subject[PATCH v4 3/8] arm64: dts: rockchip: optimize clks for rk3399 dwc3
Date
From: Wu Liang feng <wulf@rock-chips.com>

Remove unnecessary clocks, refer to rk3399 TRM, aclk_usb3 is the
parent of aclk_usb3otg0/1 and aclk_usb3_grf, and we will enable
aclk_usb3otg0/1 and aclk_usb3_grf, so don't need to enable aclk_usb3
again. In addition, the aclk_usb3_rksoc_axi_perf clk is used for usb3
performance monitor module which we don't use now, so don't need to
enable it.
