* clk: at91: add PMC master clockBoris BREZILLON2013-12-021-8/+2
| | | | | | | | | | | | | | | | | | | | | | | This patch adds new at91 master clock implementation using common clk framework. The master clock layout describe the MCKR register layout. There are 2 master clock layouts: - at91rm9200 - at91sam9x5 Master clocks are given characteristics: - min/max clock output rate These characteristics are checked during rate change to avoid over/underclocking. These characteristics are described in atmel's SoC datasheet in "Electrical Characteristics" paragraph.

* clk: at91: add PMC pll clocksBoris BREZILLON2013-12-021-0/+537
This patch adds new at91 pll clock implementation using common clk framework. The pll clock layout describe the PLLX register layout. There are four pll clock layouts: - at91rm9200 - at91sam9g20 - at91sam9g45 - sama5d3 PLL clocks are given characteristics: - min/max clock source rate - ranges of valid clock output rates - values to set in out and icpll fields for each supported output range These characteristics are checked during rate change to avoid over/underclocking. These characteristics are described in atmel's SoC datasheet in "Electrical Characteristics" paragraph.
