Subject: clk: rockchip: rk3399: Add SCLK_USB3OTGx_REF support
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=add8cef67be9eacd7a0693131309fd1b344bf53c;p=u-boot.git

clk: rockchip: rk3399: Add SCLK_USB3OTGx_REF support

The SCLK_USB3OTGx_REF clocks is used as reference clock for USB3 block.

Add simple support to get rate of SCLK_USB3OTGx_REF clocks to fix
reference clock period configuration.

Also replace use of 24000000 with the OSC_HZ constant.
