Previously, the clocks with a fixed divider would report their rate
as being the same as the one of their parent, independently of the
divider in use. This commit fixes this behaviour.
This went unnoticed as neither the jz4740 nor the jz4780 CGU code
have clocks with fixed dividers yet.

When the timekeeping multiplier is changed, the NTP error is updated to
correct the clock for the delay between the tick and the update of the
clock. This error is corrected in later updates and the clock appears as
if the frequency was changed exactly on the tick.
Remove this correction to keep t
When the length of the NTP tick changes significantly, e.g. when an
NTP/PTP application is correcting the initial offset of the clock, a
large value may accumulate in the NTP error before the multiplier
converges to the correct value. It may then take a very long time (hours
or even days) before th

Hi Andy,
This is bare metal, not VM, read my other email in this thread about
the machine on which I am testing. Sometime hang happens a little

When a divider clock has CLK_DIVIDER_READ_ONLY set, it means that the
register shall be left un-touched, but it does not mean the clock
should stop rate propagation if CLK_SET_RATE_PARENT is set
This is properly handled in qcom clk-regmap-divider but it was not in
the generic divider

A read-only divider may also have CLK_SET_RATE_PARENT flag set, in which
case it should propagate the requested rate to its parent, taking the
read-only divider value into account.
While this is done correctly in qcom's clk-regmap-divider, it is not in
the generic divider and lpc32xx.

There is now an helper function to round the rate when the
divider is read-only. Let's use it

Like divider_round_rate, a couple a of driver are doing more or less
the same operation to round the rate of the divider when it is read-only.
We can factor this code so let's provide an helper function for this

I can't apply this because you've changed the soundwire Kconfig in this
