From: Ryder Lee <ryder.lee@xxxxxxxxxxxx> This adds a property "num-pwms" in example so that we could specify the number of PWM channels via device tree.

Follow reviewers's comments: - derive the number of PWMs from the specific compatible string 2. Add mt7629 pwm description 3. Add mt7628 fixed-clock description Changes since v6: Follow reviewers's comments: - The subject should indicate this is for Mediatek Changes since v5: - Add an Acked-by tag - This file is original v4 patch 5/10 (https://patchwork.kernel.org/patch/11102577/) --- Documentation/devicetree/bindings/pwm/pwm-mediatek.txt | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/Documentation/devicetree/bindings/pwm/pwm-mediatek.txt b/Documentation/devicetree/bindings/pwm/pwm-mediatek.txt index 991728cb46cb..975d7871830d 100644 --- a/Documentation/devicetree/bindings/pwm/pwm-mediatek.txt +++ b/Documentation/devicetree/bindings/pwm/pwm-mediatek.txt @@ -9,17 +9,20 @@ Required properties: - reg: physical base address and length of the controller's registers. - #pwm-cells: must be 2.
