> This series was split-off from "Misc MMC updates" patch series [0] and the
> original patch further divided into three to help with backporting as per
> review comments [1].
>
> This series sets clock parent for eMMC to the default clock parent
> MAIN_PLL0_HSDIV5_CLKOUT for am62, am62a, & am62p/j722s SoCs. Software (DM)
> does not switch MMC clock parent correctly as per the Arasan IP requirement
> to hold the IP in reset while clock source is switched. Since muxes to
> switch clock parent are not glitch-free and the default parent is tested
> and working fine, switch to the default as a preventative action.
>
> Changes since v1:
> - split original patch into three
> - add cover-letter
> - reword patch descriptions
> - add review tags
