Hi

Sorry the delay, I was out of office last week. Comment below.

Actually it looks there is need to revert back to bus clock (or better)
in comments but keep the "pclk" property.
The specification I have tells the ic_clk is the peripheral clock which
runs the logic and the pclk (exactly pclk) is for bus interface and
where registers are.
Luis: did I interpret it right?
