This is a bit confusing. What is the maximum referring to? The raw value in the register? Or the actual divider? Personally I'd go with the maximum valid value of the register. You could get rid of the special power-of-2 handling code you added. Either way I think the message and the field name should be more explicit. > > Otherwise, we'll use whatever value has been set. > > Signed-off-by: Maxime Ripard <[email protected]> [...] The code looks correct.
