Hi, Mans Rullgard has the patches mentioned below in his kernel tree at http://git.mansr.com/?p=linux-omap;a=summary . I currently have those patches and use the following sequence to set the dss1_alwon_fck clock: /* get the rate of the parent of dpll4_m4_ck, which is dpll4_ck */ prate = clk_get_rate(clk_get_parent(dispc.dpll4_m4_ck)); /* calculate divisor so that wanted dss1_alwon_fck is prate / div * 2. * x2 because dss1_alwon_fck comes from dpll4_m4x2_ck */ div = ...; /* set the rate */ clk_set_rate(dispc.dpll4_m4_ck, prate / div); Is this the correct way to set dss1_alwon_fck? Are the patches below needed, or can dss1_alwon_fck be set some other way?

This is needed to give omapfb control over the dss1_alwon_fck rate. :100644 100644 161da12... 876eb13...
