Hi,

it turns out that problem is the read+or of the new value

i reverted my patch and changed

reg = readl_relaxed(mmsys->regs + routes[i].addr) | routes[i].val;
writel_relaxed(reg, mmsys->regs + routes[i].addr);

to

writel_relaxed(routes[i].val, mmsys->regs + routes[i].addr);

and it works too, but maybe it breaks other platforms

Interesting, I can test if it fix that similar bug on mt8173 when resume from suspend.

Thanks,
Dafna

regards Frank
