-Ingenic JZ47xx SoCs Timer/Counter Unit devicetree bindings
-==========================================================
-
-For a description of the TCU hardware and drivers, have a look at
-Documentation/mips/ingenic-tcu.rst.
-
-Required properties:
-
-- compatible: Must be one of:
- * ingenic,jz4740-tcu
- * ingenic,jz4725b-tcu
- * ingenic,jz4770-tcu
- * ingenic,x1000-tcu
- followed by "simple-mfd".
-- reg: Should be the offset/length value corresponding to the TCU registers
-- clocks: List of phandle & clock specifiers for clocks external to the TCU.
- The "pclk", "rtc" and "ext" clocks should be provided. The "tcu" clock
- should be provided if the SoC has it.
-- clock-names: List of name strings for the external clocks.
-- #clock-cells: Should be <1>;
- Clock consumers specify this argument to identify a clock. The valid values
- may be found in <dt-bindings/clock/ingenic,tcu.h>.
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The value should be 1.
-- interrupts : Specifies the interrupt the controller is connected to.
-
-Optional properties:
-
-- ingenic,pwm-channels-mask: Bitmask of TCU channels reserved for PWM use.
- Default value is 0xfc.
-
-
-Children nodes
-==========================================================
-
-
-PWM node:
----------
-
-Required properties:
-
-- compatible: Must be one of:
- * ingenic,jz4740-pwm
- * ingenic,jz4725b-pwm
-- #pwm-cells: Should be 3. See ../pwm/pwm.yaml for a description of the cell
- format.
-- clocks: List of phandle & clock specifiers for the TCU clocks.
-- clock-names: List of name strings for the TCU clocks.
-
-
-Watchdog node:
---------------
-
-Required properties:
-
-- compatible: Must be "ingenic,jz4740-watchdog"
-- clocks: phandle to the WDT clock
-- clock-names: should be "wdt"
-
-
-OS Timer node:
----------
-
-Required properties:
-
-- compatible: Must be one of:
- * ingenic,jz4725b-ost
- * ingenic,jz4770-ost
-- clocks: phandle to the OST clock
-- clock-names: should be "ost"
-- interrupts : Specifies the interrupt the OST is connected to.
