Thanks for fast reply.
I poked around DTB and i try to enable SPI, which was set to disabled, I changed it to okay, but after recompiling DTB and rebooting nothing happend.
There is also entry onewire-touch, but I don't know what to do with it.
spi@c005b000 {
compatible = "nexell,s5p6818-spi";
reg = <0xc005b000 0x100>;
interrupts = <0x0 0xc 0x0>;
dmas = <0x39 0x6 0x0 0x39 0x7 0x0>;
dma-names = "tx", "rx";
resets = <0x12 0x
