Let the mpll dividers achieve the closest rate possible, even if it means rounding the requested rate up. This is done to improve the accuracy of the rates provided by these plls to the audio subsystem Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> --- drivers/clk/meson/axg.c | 4 ++++ 1 file changed, 4 insertions(+) -- 2.14.3
