The PMON[2] firmware of this board is responsible for configure the sii9022 encoder at boot time. Due to i2c driver for lsk2000 SoC is not upstream yet, we simply replace the sii9022 with a 1024x768 panel. The i2c0 is not get used by lsdc driver for this board, so there no need to worry about DVO0.
