Do you have I2C3 bus controller device added to the list of devices
registered in the init_machine() callback, i.e. &s3c_device_i2c3
entry in smdkv210_devices[] array ?

You can refer to arch/arm/mach-exynos/mach-universal_c210.c board file
for how a complete setup for the HDMI driver should look like. It's
for Exynos4210 SoCs but it should not be much different from what you
need for S5PV210.
