Mike Looijmans 4d3f36c5e9 clk-si544: Properly round requested frequency to nearest match ... The si544 driver had a rounding problem that using the result of clk_round_rate may set the clock to yet another rate, for example: clk_round_rate(195000000) = 194999999 clk_round_rate(194999999) = 194999998 Clients would expect that after clk_set_rate(clk, freq2=clk_round_rate(clk, freq)) the chip will be running at exactly freq2. The problem was in the calculation of the feedback divider, it was always rounded down instead of to the nearest possible VCO value. After this change, the following holds true for any supported frequency: actual_freq = clk_round_rate(clk, freq); clk_set_rate(clk, actual_freq); clk_round_rate(clk, actual_freq) == actual_freq && clk_get_rate(clk) == actual_freq Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl> Fixes: 953cc3e811 ("clk: Add driver for the si544 clock generator chip") Signed-off-by: Stephen Boyd <sboyd@kernel.org>		2018-06-01 23:24:52 -07:00
