From: Thierry Reding <[email protected]> The number of resets controls is 32 times the number of peripheral register banks rather than 32 times the number of clocks. This reduces (drastically) the number of reset controls registered from 10080 (315 clocks * 32) to 224 (6 peripheral register banks * 32).
This also fixes a potential crash because trying to use any of the excess reset controls (224-10079) would have caused accesses beyond the array bounds of the peripheral register banks definition array.
