Now I checked HDMI failed at:

adapter = i2c_get_adapter(pdata->hdmiphy_bus);

dev_err(dev, "hdmiphy adapter request failed\n");
ret = -ENXIO;
goto fail_vdev;

Since pdata->hdmiphy_bus is 3, why i2c_get_adapter failed?
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.
To build the kernel with s3c_device_i2c3 S3C_DEV_I2C3 and
S5PV210_SETUP_I2C3
need to be selected in Kconfig, e.g.
diff --git a/arch/arm/mach-s5pv210/Kconfig b/arch/arm/mach-s5pv210/Kconfig
index 92ad72f..51ce100 100644

Sylwester, thank you very much for your suggestions! Now HDMI phy has
been detected after I add HDMI phy i2c bus in arch/arm/mach-s5pv210/Kconfig:
config MACH_SMDKV210
bool "SMDKV210"

select S3C_DEV_USB_HSOTG
and arch/arm/mach-s5pv210/mach-smdkv210.c:
static struct platform_device *smdkv210_devices[] __initdata = {
&s3c_device_adc,
&s3c_device_cfcon,

};
Now kernel prints the following HDMI related:

How can I test the HDMI output whether it's OK? Which /dev/video is real
HDMI output? I have used
http://git.infradead.org/users/kmpark/public-apps hdmi test program buf
failed:
root@linaro-developer:/opt# ./tvdemo /dev/video7 720 480 0 0
ERROR(main.c:80) : VIDIOC_S_FMT failed: Invalid argument

root@linaro-developer:/opt#
Maybe I still miss some configuration in mach-smdkv210.c.
