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;

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,
