If anyone has any objections, please let me know. ------------------ From: Dmitry Baryshkov [ Upstream commit f45fd3dbb5f6d60a8b31d5cc4affaf1ef40163b3 ] On SM8250 most of the video clocks are powered by the MMCX domain, while the PLL is powered on by the MX domain. Extend the driver to support scaling both power domains, while keeping compatibility with the existing DTs, which define only the MX domain.
