    Subject[PATCH v4 1/1] dt-bindings: pwm: ti,pwm-omap-dmtimer: Update binding for yaml
    Date
    Update for yaml and remove the old txt binding.

    As we can replace most of the custom timer API with standard Linux
    frameworks such as clock framework, let's tag the properties for
    ti,prescaler and ti,clock-source as deprecated.

    Changes since v3:

    - No changes, reposted without patch 1/2. The pwm.yaml related issues got
    fixed by commit 05b743db9d8c ("dt-bindings: pwm: restrict node name
    suffixes")

    Changes since v2:

    - Reviewed-by collected from Krzysztof, no changes

    -* OMAP PWM for dual-mode timers
    -
    -Required properties:
    -- compatible: Shall contain "ti,omap-dmtimer-pwm".
    -- ti,timers: phandle to PWM capable OMAP timer. See timer/ti,timer-dm.yaml for info
    - about these timers.
    -- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
    - the cells format.
    -
    -Optional properties:
    -- ti,prescaler: Should be a value between 0 and 7, see the timers datasheet
    -- ti,clock-source: Set dmtimer parent clock, values between 0 and 2:
    - - 0x00 - high-frequency system clock (timer_sys_ck)
    - - 0x01 - 32-kHz always-on clock (timer_32k_ck)
    - - 0x02 - external clock (timer_ext_ck, OMAP2 only)
    -
    -Example:
    - pwm9: dmtimer-pwm@9 {
    - compatible = "ti,omap-dmtimer-pwm";
    - ti,timers = <&timer9>;
    - #pwm-cells = <3>;
