Please test the ES8316 works when booting Linux from a U-Boot where 
ROCKCHIP_IODOMAIN and SPL_ROCKCHIP_IODOMAIN is *disabled*.

Having the IO domain properly configured from U-Boot may make you think 
that the ES8316 always work in the Linux kernel but that may not be the 
case depending on probe order e.g. between the IO domain driver in Linux 
and the ES8316 (if the original issue is indeed related to IO domain).
