Although disp1 and disp2 have 7.1 divisors, their corresponding registers in the clk_rst block are not the interface to program the divisors. Setting the generic DIV_U71 flag may cause the code to attempt to program the clock at a different divisor, which will confuse any code attempting to use that clock since it isn't actually being divided.
Signed-off-by: Robert Morell <[email protected]> --- This bugfix applies to Linus's 2.6.39. However, since no drivers are using these clocks in that kernel, this should probably just be queued up for 3.0. It also applies to linux-tegra-2.6.3[69].
