Sorry, I would take care for this and all future pull requests.

Sure.

OK.

Yes, twd would rely on its calibration if we don't pass it.
Although it would break other stuff like cpu-freq, but they are not
yet upstreamed.

I would remove it from fixes branch and schedule it later.

Out of several possibilities (h/w wise) to select same clock parent,
Linux was considering just one value. When bootloader programmed
different (valid) value to select a clock parent then Linux breaks.

Here, we just try to list all possibilities which can lead to same
clock selection thus making Linux independent of bootloader selection
values.

This was discussed in following thread

spear320-evb board is designed for EXTENDED_MODE only, hence it would
not boot correctly in current form (pinctrl part for some devices would
fail). I would update the commit message.

Thanks for review. I would update the branch as soon as possible and
send a fresh pull request.
