Subject: [PATCH v3] dt-bindings: timer: Convert faraday,fttmr010 to yaml
Converts timer/faraday,fttmr010.txt to yaml.
Signed-off-by: Corentin Labbe <clabbe@...libre.com>
---
Changes since v1:
- added moxart example
- relaxed some contraints as driver only support one clock and one
interrupt (as used by moxa,moxart-timer)
Changes since v2:
- increased max size of interrupts
- fixed all issues reported by Rob https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20220126160021.3537591-1-clabbe@baylibre.com
All aspeed-bmc-vegman*dts are expected to fail and will be fixed via:

-Faraday Technology timer
-
-This timer is a generic IP block from Faraday Technology, embedded in the
-Cortina Systems Gemini SoCs and other designs.
-
-Required properties:
-
-- compatible : Must be one of
- "faraday,fttmr010"
- "cortina,gemini-timer", "faraday,fttmr010"
- "moxa,moxart-timer", "faraday,fttmr010"
- "aspeed,ast2400-timer"
- "aspeed,ast2500-timer"
- "aspeed,ast2600-timer"
-
-- reg : Should contain registers location and length
-- interrupts : Should contain the three timer interrupts usually with
- flags for falling edge
-
-Optionally required properties:
-
-- clocks : a clock to provide the tick rate for "faraday,fttmr010"
-- clock-names : should be "EXTCLK" and "PCLK" for the external tick timer
- and peripheral clock respectively, for "faraday,fttmr010"
-- syscon : a phandle to the global Gemini system controller if the compatible
- type is "cortina,gemini-timer"
-
-Example:
-
-timer@...00000 {
- compatible = "faraday,fttmr010";
- reg = <0x43000000 0x1000>;
- interrupts = <14 IRQ_TYPE_EDGE_FALLING>, /* Timer 1 */
- <15 IRQ_TYPE_EDGE_FALLING>, /* Timer 2 */
- <16 IRQ_TYPE_EDGE_FALLING>; /* Timer 3 */
- clocks = <&extclk>, <&pclk>;
- clock-names = "EXTCLK", "PCLK";
-};
