This commit corrects the printing of the IPU clock error percentage if it is between -0.1% to -0.9%. For example, if the pixel clock requested is 27.2 MHz but only 27.0 MHz can be achieved the deviation is -0.8%. But the fixed point math had a flaw and calculated error of 0.2%. Before: Clocks: IPU 270000000Hz DI 24716667Hz Needed 27200000Hz IPU clock can give 27000000 with divider 10, error 0.2% Want 27200000Hz IPU 270000000Hz DI 24716667Hz using IPU, 27000000Hz After: Clocks: IPU 270000000Hz DI 24716667Hz Needed 27200000Hz IPU clock can give 27000000 with divider 10, error -0.8% Want 27200000Hz IPU 270000000Hz DI 24716667Hz using IPU, 27000000Hz Signed-off-by: Leo Ruan <tingquan.ruan@cn.bosch.com> Signed-off-by: Mark Jonas <mark.jonas@de.bosch.com> Reviewed-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Link: https://lore.kernel.org/r/20220207151411.5009-1-mark.jonas@de.bosch.com |
