Basically, this approach looks OK to me.

BTW, I have some comments and need to update...

Why? In addition, this causes build error with s3c6400_defconfig.

Happens build error with s5pv210_defconfig

arch/arm/plat-samsung/devs.c:1375: error: 'S3C_PA_USB_PHY' undeclared here
(not in a function)
make[2]: *** [arch/arm/plat-samsung/devs.o] Error 1
make[1]: *** [arch/arm/plat-samsung] Error 2
make[1]: *** Waiting for unfinished jobs....

And another build error with exynos_defconfig...

arch/arm/mach-exynos/built-in.o: In function `.LANCHOR1':
setup-i2c0.c:(.data+0x8080): undefined reference to
`s5p_usb_phy_pmu_isolation'

If possible, please to use 'ARM: [sub-arch dir name]: [subject]' format.
So I preferred to use 'ARM: EXYNOS: Enabling samsung-usbphy driver for
EXYNOS4210' on that.

Please make sure your patch has no problem for kernel compilation before
submitting...

Thanks.

Best regards,
Kgene.
