OK, I'll add comment about it and if you ok, I'll send a further patchset to set relation
between fin_pll and xusbxti/xxti by reading XOM pin of chipid register.

> Are there only 2 gate block clocks? By the way, how are they going to be handled by respective drivers? There is no mainline support for them right now, but you should be aware that adding them will cause common clock framework to disable them if not claimed by any driver.
OK, I'll add remaing clock gate of GATE_BLOCK as following.
- CLK_BLOCK_MFC MFC_BLK
- CLK_BLOCK_CAM CAM_BLK

> Are all these frequencies above calculated exactly? For correct operation of rate setting code, it is necessary for frequency values specified in these arrays to be exact, not rounded.
When I implemnted exynos3250_vpll_rates array, I used 'VPLL PMS Value' in Exynos3250 TRM without modification.
This rate value of exynos3250_vpll_rates is correct.
