0001 Device Tree Clock bindings for arch-at91
0002
0003 This binding uses the common clock binding[1].

0006
0007 Slow Clock controller:
0008
0009 Required properties:
0010 - compatible : shall be one of the following:
0011 "atmel,at91sam9x5-sckc",
0012 "atmel,sama5d3-sckc",
0013 "atmel,sama5d4-sckc" or
0014 "microchip,sam9x60-sckc":
0015 at91 SCKC (Slow Clock Controller)
0016 - #clock-cells : shall be 1 for "microchip,sam9x60-sckc" otherwise shall be 0.
0017 - clocks : shall be the input parent clock phandle for the clock.
0018
0019 Optional properties:
0020 - atmel,osc-bypass : boolean property. Set this when a clock signal is directly
0021 provided on XIN.
0022
0023 For example:
0024 sckc@fffffe50 {
0025 compatible = "atmel,at91sam9x5-sckc";
0026 reg = <0xfffffe50 0x4>;
0027 clocks = <&slow_xtal>;
0028 #clock-cells = <0>;
0029 };
0030
0031 Power Management Controller (PMC):
0032
0033 Required properties:
0034 - compatible : shall be "atmel,<chip>-pmc", "syscon" or
0035 "microchip,sam9x60-pmc"
0036 <chip> can be: at91rm9200, at91sam9260, at91sam9261,
0037 at91sam9263, at91sam9g45, at91sam9n12, at91sam9rl, at91sam9g15,
0038 at91sam9g25, at91sam9g35, at91sam9x25, at91sam9x35, at91sam9x5,
0039 sama5d2, sama5d3 or sama5d4.
0040 - #clock-cells : from common clock binding; shall be set to 2. The first entry
0041 is the type of the clock (core, system, peripheral or generated) and the
0042 second entry its index as provided by the datasheet
0043 - clocks : Must contain an entry for each entry in clock-names.
0044 - clock-names: Must include the following entries: "slow_clk", "main_xtal"
0045
0046 Optional properties:
0047 - atmel,osc-bypass : boolean property. Set this when a clock signal is directly
0048 provided on XIN.
0049
0050 For example:
0051 pmc: pmc@f0018000 {
0052 compatible = "atmel,sama5d4-pmc", "syscon";
0053 reg = <0xf0018000 0x120>;
0054 interrupts = <1 IRQ_TYPE_LEVEL_HIGH 7>;
0055 #clock-cells = <2>;
0056 clocks = <&clk32k>, <&main_xtal>;
0057 clock-names = "slow_clk", "main_xtal";
0058 };
