Quoting Alexandre Courbot (2013-05-25 19:56:31) > Tegra has a blink timer register that allows to modulate the > clk_32k clock before outputting it. Since clk_32k is presented to the > kernel as a fixed clock, make sure this register does not tamper with > the clock frequency and that clk_32k is outputted as-is, similarly to > what is done on t20 and t30. > > Signed-off-by: Alexandre Courbot <acourbot@xxxxxxxxxx> > Acked-by: Stephen Warren <swarren@xxxxxxxxxx> Taken into clk-next.
