clk: at91: add a driver for the h32mx clock

2014-09-22T09:38:59Z

Newer SoCs have two different AHB interconnect. The AHB 32 bits Matrix interconnect (h32mx) has a clock that can be setup at the half of the h64mx clock (which is mck). The h32mx clock can not exceed 90 MHz. Signed-off-by: Alexandre Belloni Acked-by: Boris Brezillon Signed-off-by: Nicolas Ferre

clk: at91: add slow clks driver

2014-05-07T16:27:45Z

AT91 slow clk is a clk multiplexer. In some SoCs (sam9x5, sama5, sam9g45 families) this multiplexer can choose among 2 sources: an internal RC oscillator circuit and an oscillator using an external crystal. In other Socs (sam9260 family) the multiplexer source is hardcoded with the OSCSEL signal. Signed-off-by: Boris BREZILLON Acked-by: Mike Turquette Signed-off-by: Nicolas Ferre

clk: at91: add PMC pll clocks

2013-12-02T14:31:22Z

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. Signed-off-by: Boris BREZILLON Acked-by: Mike Turquette Signed-off-by: Nicolas Ferre

ARM: at91: move at91_pmc.h to include/linux/clk/at91_pmc.h

2013-12-02T14:22:15Z

This patch moves at91_pmc.h header from machine specific directory (arch/arm/mach-at91/include/mach/at91_pmc.h) to clk include directory (include/linux/clk/at91_pmc.h). We need this to avoid reference to machine specific headers in clk drivers. Signed-off-by: Boris BREZILLON Acked-by: Felipe Balbi Acked-by: Mike Turquette Signed-off-by: Nicolas Ferre
