The cam_mclk clock is generated through the following clocks chain:
dpll4 - dpll4_m5 - dpll4_m5x2 - cam_mclk
As dpll4_m5 and dpll4_m5x2 do not driver any clock other than cam_mclk,
back-propagate the cam_clk rate changes up to dpll4_m5.

Hello,
Now that the OMAP3 supports the common clock framework, clock rate
back-propagation is available for the ISP clocks. Instead of setting the
cam_mclk parent clock rate to control the cam_mclk clock rate, we can mark the
dpll4_m5x2_ck_3630 and cam_mclk clocks as supporting back-propagation,
Now that the cam_mclk rate changes are back-propagated to dpll4_m5_ck we
can set the cam_mclk rate directly instead of manually setting the rate
of the parent clock.

This is a static checker fix. In the ttusb_process_muxpack() we do:
cc = (muxpack[len - 4] 8) | muxpack[len - 3];
