| | * clk: at91: allow configuring peripheral PCR layoutAlexandre Belloni2019-04-251-0/+9
| |/ | | | | | | | | | | | | | | | | | | | | The PCR register actually changed layout for each SoC. By chance, this didn't have impact on sama5d[2-4] support but since sama5d3, PID is seven bits wide and sama5d4 and sama5d2 don't have DIV. For the DT backward compatibility, keep the layout as is.
