The HDMI clock has to be reconfigured for different video modes. However, the precision of the supplying SoC clock on SH-Mobile systems is often insufficient. This patch allows to additionally reconfigure the parent clock to achieve the optimal HDMI clock frequency, in case this is supported by the platform.
