The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and MCLK. The old devices had defined the peripheral clock enable bit at PM. On the newer devices this was extracted on a dedicated memory section called Master Clock (MCLK). This change excludes the dedicated bindings in favor of a generic approach that cover all cases. Now the clocks properties is complemented by the atmel,assigned-clocks property. It gives the liberty to user to customize the clock source from a generic clock or configure the direct connections. All peripherals drivers were reworked with the newer solution. Signed-off-by: Gerson Fernando Budke <nandojve@gmail.com>
