[PATCH 0/2] clk: si5351: Multisynth 6-7 fixes

The second synthesis stage in the Si5351 clock generator consists of six *fractional* multisynth dividers (MS0 .. MS5) and two *even-integer* dividers (MS6 and MS7). The current si5351 driver implementation does not handle MS6 and MS7 correctly, this leads to wrong rates on output 6 and 7. This p

[PATCH 1/2] clk: si5351: fix .round_rate for multisynth 6-7

The divider calculation for multisynth 6 and 7 differs from the calculation for multisynth 0-5. For MS6 and MS7, set MSx_P1 directly, MSx_P1=divide value [AN619, p. 6]. Referenced document: [AN619] Manually Generating an Si5351 Register Map, Rev. 0.4 Signed-off-by: Sergej Sawazki --- drivers/c
