Quoting Guodong Xu (2016-06-29 01:45:54) > From: Xinliang Liu <xinliang.liu@linaro.org> > > In the bootloader of HiKey/96boards, syspll and media_syspll clk > was initialized to 1.19GHz. So, here changes it in kernel accordingly. > > 1.19GHz was chosen over 1.2GHz because at 1.19GHz we get more precise > HDMI pixel clock (1.19G/16 = 74.4MHz) for 1280x720p@60Hz HDMI > (74.25MHz required by standards). Closer pixel clock means better > compatibility to HDMI monitors. > > Signed-off-by: Guodong Xu <guodong.xu@linaro.org> > Signed-off-by: Xinliang Liu <xinliang.liu@linaro.org> Applied.
