Uwe Kleine-König f61b9fc27e ARM: mxs/clock-mx28: fix up name##_set_rate ... For the lcdif clock get_rate looks as follows: read div from HW_CLKCTRL_DIS_LCDIF.DIV return clk_get_rate(clk->parent) / div with clk->parent being ref_pix_clk on my system. ref_pix_clk's rate depends on HW_CLKCTRL_FRAC1.PIXFRAC. The set_rate function for lcdif does: parent_rate = clk_get_rate(clk->parent); based on that calculate frac and div such that parent_rate * 18 / frac / div is near the requested rate. HW_CLKCTRL_FRAC1.PIXFRAC is updated with frac HW_CLKCTRL_DIS_LCDIF.DIV is updated with div For this calculation to be correct parent_rate needs to be initialized not with the clock rate of lcdif's parent (i.e. ref_pix) but that of its grandparent (i.e. ref_pix' parent == pll0_clk). The obvious downside of this patch is that now set_rate(lcdif) changes its parent's rate, too. Still this is better than a wrong rate.
