I would like to ask bout DSP_CLK setting of i.MX51.
My customer wants to change DSP_CLK setting of i.MX51.
Now they are using display interface of i.MX51 to output display data with DSP_CLK’s FALLING edge.
And they want to change it to output display data with DSP_CLK’s RISING edge.
It is possible?
They are using your LinuxBSP(L.2.6.31 base) and they believe that they should modify the source code as below to achieve that.
In source file ipu_common.c, and in ipu_pixel_clk_set_rate() function,
_raw_writel((dev/16)<< 16, DI_BS_CLKGEN1(clk->id));
The above statement should change as below;
_raw_writel(((dev/16)*2)<< 16 | (dev/16) , DI_BS_CLKGEN1(clk->id));
Is it true?
