I tried clearing a bit by writing to hw_clkctrl_gpmi_clr, then
busy-waiting for it to actually clear. My board hung. The data sheet
agrees, these registers do not have _set, _clr, _tog, so fix up the
definitions. git grep -E 'clkctrl_(gpmi|ssp[0-9])_' says that nobody
uses those non-existing ops registers.

The comment says to clear the bypass bit, but in fact it sets it, thus
selecting ref_xtal. And the next line of code does not set the divider
to 12, but to (the reset value of) 1.

The data sheet says that the DIV field cannot change while the CLKGATE
bit is set or modified. So do it a little more carefully, by first
clearing the bit, waiting for that to appear, then setting the DIV
field.

This allows a board file to set the gpmiclk to something other than
the default 24 MHz based on ref_xtal.
I don't have an mx23-based board, but I believe there's a bug in the
current mxs_get_gpmiclk: According to the data sheet, the gpmiclk can
be derived from ref_io, not ref_cpu. Since other clocks are also
derived from ref_io, it seems most sensible to require the board file
to set that appropriately first, then derive the divider from its
current setting.
For mx28 boards, OTOH, there's a separate ref_gpmi only used for
clk_gpmi. For simplicity, if !xtal, simply enable that at its maximum
frequency.

You're right, patch was lost (..just because the list of patches for
i.MX was very long and I have not seen..), I found the series again.
I applied the first 3 patches, they are improvements / clarifications.
The fourth patch has no user, so I ask who is suing it. Nevertheless,
patch 4/4 breaks some boards (I found at least "xfi3") because it is
compiled even for not i.MX boards and then prototype is missing:

Thanks.
> The fourth patch has no user, so I ask who is suing it.
I had a user in the branch I was working on, from which I tried to carve
out some upstreamable chunks. Unfortunately, the focus internally has
now shifted away from that mx28 board, so I don't know if and when I'll
be working on that again. But I'll try to remember to fix the break you
report the next time around.
Thanks,
Rasmus
