I agree that in the end the block gates will have to be added. However
currently drivers do not request block gates and enable them.
Considering that common clock framework disables all unused clocks by
default, this will lead to all the gate block clocks being disabled,
which is not desired.
My opinion on this is that block gate clocks should be added in separate
patch along with patches adding code to get and enable them.

The TRM actually lists this as 267, 3, 2, 32768, and according to the
equation it will be 535000015 Hz. Looks like a typo in the data sheet,
as 266, 3, 2, 32768 gives 533000015, which is almost exactly 533 MHz.

The TRM lists this as 124, 2, 2, 49152 and calculated frequency is
374250034. This one also looks like a typo. 123, 2, 2, 49512 would give

Well, after checking the values using PLL equation for VPLL, as
specified in TRM and used by clk-pll.c, the values don't match.
Keep in mind that the values must be exact, _not_ rounded, while in the
TRM they are rounded. Moreover it looks like several frequencies in TRM
are off by 1 in M coefficient. Please see above.
