I believe this may have been discussed previously as indicated
by Mike's Ack of patch 1 indicating the series can go through my tree.
I am quite happy to proceed with that approach for v3.20.
But I'll leave the patchset out there until next week to
give Mike and others a chance to say otherwise.

I see v2 has been posted which solicits another Ack from Mike.
I will continue to hold fire.

Please ignore that, the v2 I saw was for a different patchset.

Hi Ulrich,
Looking at other clock rates in /sys/kernel/debug/clk/*/clk_rate, it seems
there are more that do not match the values in the CPG block diagram in the
sh73a0 datasheet. Some of these may be due to genuine different divider values,
but at least the value of the Z clock for the Cortex A9 (598 instead of 1196
MHz) seems to be wrong.
for i in /sys/kernel/debug/clk/*/clk_rate; do echo -n "$(basename $(dirname
$i)) : "; cat $i; done | sed -e 's/$/ Hz/g' -e 's/000000 Hz$/ MHz/g' -e 's/000
Hz$/ kHz/g'
hsi : 178285714 Hz (datasheet: 208 MHz)
m1 : 208 MHz (datasheet: 312 MHz)
msu : 9750 kHz (datasheet: 124.8 MHz)
sdhi0 : 69333333 Hz (datasheet: 96 MHz)
sdhi1 : 69333333 Hz (datasheet: 96 MHz)
sdhi2 : 69333333 Hz (datasheet: 96 MHz)
spua : 52 MHz (datasheet: 208 MHz)
spuv : 52 MHz (datasheet: 208 MHz)
zb : 208 MHz (datasheet: 104 MHz)
z : 598 MHz (datasheet: 1196 MHz)
zg : 299 MHz (datasheet: 201.5 MHz)
Gr{oetje,eeting}s,

I'm fine with you taking the clk patch through you tree.
