So, just changelog is provided here. It would be really nice to queue them to v4.1. Patches 2/3 and 3/3 are dependent to the patch 1/7 from [1] "clk: replace div_mask() by clk_div_mask()". The series was tested with 8250_dw UART driver on Intel Braswell. [1] http://www.spinics.net/lists/kernel/msg1958958.html Changelog v3: - add patch 2/3 to simplify further usage - don't use mult_frac() due to potential overflow on 32 bit kernels - guarantee in ->round_rate() that m and n will not overflow Changelog v2: - move to rational_best_approximation() and mult_frac() - add patch 2/2 Andy Shevchenko (3): clk: fractional-divider: fix sparse warnings clk: fractional-divider: keep mwidth and nwidth internally clk: fractional-divider: switch to rational best approximation drivers/clk/Kconfig | 1 + drivers/clk/clk-fractional-divider.c | 86 +++++++++++++++++++++--------------- include/linux/clk-provider.h | 3 +- 3 files changed, 54 insertions(+), 36 deletions(-) -- 2.1.4
