Right so you're saying you'd prefer something like this drivers/media/i2c/ov8865.c I can drop the dependency on "xvclk" as a dependency in this series. >> + >> + clock-frequency: >> + description: >> + Frequency of the xvclk clock in Hertz. > Could you instead use the frequency already set, using assigned-clock* in > the example? Almost certainly yes. Yeah, I do that so. --- bod
