-Power Management Controller (PMC):

-Required properties:
-- compatible : shall be "atmel,<chip>-pmc", "syscon" or
-	"microchip,sam9x60-pmc"
-	<chip> can be: at91rm9200, at91sam9260, at91sam9261,
-	at91sam9263, at91sam9g45, at91sam9n12, at91sam9rl, at91sam9g15,

-	sama5d2, sama5d3 or sama5d4.
-- #clock-cells : from common clock binding; shall be set to 2. The first entry
-  is the type of the clock (core, system, peripheral or generated) and the
-  second entry its index as provided by the datasheet
-- clocks : Must contain an entry for each entry in clock-names.
-- clock-names: Must include the following entries: "slow_clk", "main_xtal"
-
-Optional properties:
-- atmel,osc-bypass : boolean property. Set this when a clock signal is directly
-  provided on XIN.
-
-For example:
-	pmc: pmc at f0018000 {
-		compatible = "atmel,sama5d4-pmc", "syscon";
-		reg = <0xf0018000 0x120>;
-		interrupts = <1 IRQ_TYPE_LEVEL_HIGH 7>;
-		#clock-cells = <2>;
-		clocks = <&clk32k>, <&main_xtal>;
-		clock-names = "slow_clk", "main_xtal";

+
+description:
+  The power management controller optimizes power consumption by controlling all
+  system and user peripheral clocks. The PMC enables/disables the clock inputs
+  to many of the peripherals and to the processor.
