When adding in the indexes for this clock-controller we missed
GCC_CAMSS_CSI2_AHB_CLK, GCC_CAMSS_CSI2_CLK, GCC_CAMSS_CSI2PHY_CLK,
GCC_CAMSS_CSI2PIX_CLK and GCC_CAMSS_CSI2RDI_CLK.
Add them in now.

No fixes tag because camss is a not-yet-enabled feature for msm8939.
Also didn't rename ftbl_gcc_camss_csi0_1_clk now that csi2 uses it
to avoid not-required-churn... should it be done anyway ?

Bindings must be a separate patch.
Please run scripts/checkpatch.pl and fix reported warnings. Some
warnings can be ignored, but the code here looks like it needs a fix.
Feel free to get in touch if the warning is not clear.
Best regards,
Krzysztof

An aesthetic choice with no right answer but, downstream calls it
ftbl_gcc_camss_csi0_1_2_clk,
maybe that's reasonable.
Assuming Krz's comments acted upon.
