Now I have even simpler idea. Don't add new clock id but just define
here the CLK_TSADC as:
GATE(CLK_TSADC, "tsadc", "aclk133", E4X12_GATE_BUS_FSYS1, 16, 0, 0);

With this change the second patch wouldn't be needed however this does
not reflect the Exynos 4x12 datasheet.

Any comments?

Best regards,
Krzysztof
