The problem is that McSPI clocks is derived from DPLL4 which has a 96 MHz output. I need to change the DPLL4 clock in Linux, and need everything else working (Except USB, which need 48MHz). Analysing the kernel code, I couldn't find where the DPLL4 is set, or how can I change it without screw all others clocks. Any help would be appreciated. Thanks, Danilo M. Caravana
