Which speed are the SS clocks ?The AHB SS clk is running at 300 MHz and the SS clk at 150 MHz. SS clk is at the expected rate but the AHB SS clk has a higher rate that what's expected. In the probing function only the SS clk rate is explicitly set. I tried to set the AHB clk rate as well and removed the delays. This didn't fix the framework selftests at boot time. Is there any reason the AHB SS clk rate isn't explicitly set when probing the driver? (Should it?)It probably shouldn't. The AHB clock is shared by most of the drivers, some of them actually using that clock to generate their signals. You would have to unbreak all those drivers first, which is probably not needed at all. I haven't seen a case where a block had a module clock and did care for its AHB clock rate.
OK, makes sense. I'll wait for Corentin to test the series, and I'll send a v2 only fixing the typos then. Thanks!
