[PATCH v3 0/3] clk: fractional-divider: do a clean up

From: Andy Shevchenko
Date: Wed Apr 01 2015 - 06:09:17 EST

Patches are self-explanatory I think. 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
