clock_sun6i.c is used for sun6i, sun8i and sun50i SoC families. PLL1 clock sets the default system clock, defined as: sun6i: 1008000000 sun8i: 1008000000 sun50i: 816000000 With the current calculation, m = 2 and k = 3. Solving for n, this results 28. Solving back: (24MHz * 28 * 3) / 2 = 1008MHz However if the requested clock is 816, n is 22.66 rounded to 22, which results: (24MHz * 28 * 3) / 2 = 792MHz Changing k to 4 satisfies both system clocks: (24E6 * 21 * 4) / 2 = 1008MHz (24E6 * 17 * 4) / 2 = 816MHz Signed-off-by: Stefan Mavrodiev <stefan@olimex.com> Acked-by: Jagan Teki <jagan@amarulasolutions.com> |
