add a comment. If this is a patch from upstream, can we do cherry pick it? It might have more context around this.

yeah, this is sync from two sources. Linux upstream 6.6.52 + Aspeed SDK 9.7, whatever changes were independant, i cherrypicked them. Some changes are part of overall merge which spans other driver changes so couldn't cherry pick mmc alone out of them. example: AspeedTech-BMC@85cb395
