-Alphascale asm9260 Watchdog timer
-
-Required properties:
-
-- compatible : should be "alphascale,asm9260-wdt".
-- reg : Specifies base physical address and size of the registers.
-- clocks : the clocks feeding the watchdog timer. See clock-bindings.txt
-- clock-names : should be set to
- "mod" - source for tick counter.
- "ahb" - ahb gate.
-- resets : phandle pointing to the system reset controller with
- line index for the watchdog.
-- reset-names : should be set to "wdt_rst".
-
-Optional properties:
-- timeout-sec : shall contain the default watchdog timeout in seconds,
- if unset, the default timeout is 30 seconds.
-- alphascale,mode : three modes are supported
- "hw" - hw reset (default).
- "sw" - sw reset.
- "debug" - no action is taken.
-
-Example:
-
-watchdog0: watchdog@80048000 {
- compatible = "alphascale,asm9260-wdt";
- reg = <0x80048000 0x10>;
- clocks = <&acc CLKID_SYS_WDT>, <&acc CLKID_AHB_WDT>;
- clock-names = "mod", "ahb";
- interrupts = <55>;
- resets = <&rst WDT_RESET>;
- reset-names = "wdt_rst";
- timeout-sec = <30>;
- alphascale,mode = "hw";
-};
Makes alphascale-asm9260 dt bindings adhere to the dt json-schema by replacing txt file with yaml file. CHANGELOG from v1: - drop quotes in "$ref" value - update compatible string from board name to node name - drop "Olof Johansson" from maintainers - update "compatible" property from enum to const - drop generic reset description Signed-off-by: Om Parikh <hack3r-0m@proton.me> --- .../watchdog/alphascale,asm9260-wdt.yaml | 69 +++++++++++++++++++ .../bindings/watchdog/alphascale-asm9260.txt | 35 ---------- 2 files changed, 69 insertions(+), 35 deletions(-) create mode 100644 Documentation/devicetree/bindings/watchdog/alphascale,asm9260-wdt.yaml delete mode 100644 Documentation/devicetree/bindings/watchdog/alphascale-asm9260.txt
