     It turned out that VIN1 signal VI1_CLK conflicts with Ether signal 
ETH_REF_CLK.
So I'm a bit at a loss here: whether I should totally remove VIN1 device 
if I'm going
to add Ether device, or add a BOCK-W specific submenu to Kconfig, or add 
driver
specific #ifdef's in the code to disable VIN1 if sh_eth driver is 
enabled?...
