This patch adds clock rate propagation support for clkctrl clocks. This
is needed on am33xx beaglebone black device at least, otherwise the
display does not work. Similar problem appears to be present on am43xx
but haven't heard of any reports of such so far, maybe Jyri can confirm
this?
I think I was also hitting this with the system timers with ti-sysc
where set_parent() would fail unless the dts has the following for
timers:
clocks = <&l4_wkup_clkctrl OMAP4_TIMER1_CLKCTRL 24>;
So bit 24 instead of 0.
Hmm so should we have all the timers use bit 0 in the dtsi?
Or default to bit 24 for all of them?
Who is going to control the clkctrl clock for the timers if you just
control the opt clock? Also, ain't the bit 24 the clksel mux setting?
Tweaking that would seem wrong...
If you were facing problems with setting the clock source, we could
maybe just apply the CLK_SET_RATE_PARENT globally to all clkctrl clocks
(modify the patch #1 in this series to always set the flag, instead of
clecking against the CLKF_xyz flag.) Any thoughts?
