Subject: [PATCH v5 3/8] arm64: dts: rockchip: optimize clks for rk3399 dwc3
Date: Tue, 9 Feb 2021 20:23:45 +0100 [thread overview]
Message-ID: <20210209192350.7130-3-jbx6244@gmail.com> (raw)
In-Reply-To: <20210209192350.7130-1-jbx6244@gmail.com>
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.
