Hi Stephen,
on recent linux-next (from 20200214 on)my rk3399-roc-pc board refuses to boot.
(s. below dmesg) with __clk_core_init: Failed to get phase for clk 'sdmmc_drv'
Git bisecting points to the following commit:
2760878662a290ac57cff8a5a8d8bda8f4dddc37 is the first bad commit
commit 2760878662a290ac57cff8a5a8d8bda8f4dddc37
Author: Stephen Boyd <sboyd@kernel.org>
Date: Wed Feb 5 15:28:02 2020 -0800
clk: Bail out when calculating phase fails during clk registration
Bail out of clk registration if we fail to get the phase for a clk that
has a clk_ops::get_phase() callback. Print a warning too so that driver
authors can easily figure out that some clk is unable to read back phase
information at boot.

Could you please clarify ? Anyway, it looks to me that the problem is coming from drivers/clk/rockchip/clk-mmc-phase.c:55 This HW has both a coarse phase setting and a fine delay-based setting. Delay based phase cannot be computed if the rate is zero (if the clock is orphaned for ex) However, I think it is still valid for CCF to call .get_phase() and except an answer, even the rate of the clock is zero. IOW, if the rate is 0, I think .get_phase() should not return -EINVAL. It should return 0 (0Hz => constant signal => no phase shift).

Just a drive-by comment, but why constant signal means no phase shift? Shouldn't the phase should be something against its counterpart? e.g, if there's no mmc cmd or data in flight, how could we know its phase from the interface.. And why it should return 0? some clk HW entities has a default phase against its counterpart in the comsumer side, maybe 90 or 180 degree. > > [0]: https://lkml.kernel.org/r/20200225134248.919889-1-maxime@cerno.tech > >> >> 2760878662a290ac57cff8a5a8d8bda8f4dddc37 is the first bad commit >> commit 2760878662a290ac57cff8a5a8d8bda8f4dddc37 >> Author: Stephen Boyd <sboyd@kernel.org> >> Date: Wed Feb 5 15:28:02 2020 -0800 >> >> clk: Bail out when calculating phase fails during clk registration >> Bail out of clk registration if we fail to get the phase for a clk >> that >> has a clk_ops::get_phase() callback.
