From: Douglas Anderson Subject: [PATCH] clk: rockchip: Don't yell about bad mmc phases when getting Date: Fri, 3 May 2019 14:22:08 -0700 At boot time, my rk3288-veyron devices yell with 8 lines that look like this: [ 0.000000] rockchip_mmc_get_phase: invalid clk rate This is because the clock framework at clk_register() time tries to get the phase but we don't have a parent yet. While the errors appear to be harmless they are still ugly and, in general, we don't want yells like this in the log unless they are important. There's no real reason to be yelling here. We can still return -EINVAL to indicate that the phase makes no sense without a parent. If someone really tries to do tuning and the clock is reported as 0 then we'll see the yells in rockchip_mmc_set_phase().
