Changes since v3: 1. Remove pwm-consumers.yaml as they do not give anything new except description. 2. Leave pwm.txt with consumers description. 3. Add acks.
Changes since v2: 1. Change also pwm-sprd.txt
Changes since v1: 1. Indent example with four spaces (more readable), 2. Change pattern for pwm nodes, 3. Remove $ref from #cells. --- .../bindings/display/bridge/ti,sn65dsi86.txt | 2 +- .../bindings/pwm/atmel-hlcdc-pwm.txt | 2 +- .../devicetree/bindings/pwm/atmel-pwm.txt | 2 +- .../devicetree/bindings/pwm/atmel-tcb-pwm.txt | 2 +- .../bindings/pwm/brcm,bcm7038-pwm.txt | 2 +- .../bindings/pwm/brcm,iproc-pwm.txt | 2 +- .../devicetree/bindings/pwm/brcm,kona-pwm.txt | 2 +- .../devicetree/bindings/pwm/img-pwm.txt | 2 +- .../devicetree/bindings/pwm/imx-pwm.txt | 2 +- .../devicetree/bindings/pwm/imx-tpm-pwm.txt | 2 +- .../bindings/pwm/lpc1850-sct-pwm.txt | 2 +- .../devicetree/bindings/pwm/mxs-pwm.txt | 2 +- .../bindings/pwm/nvidia,tegra20-pwm.txt | 2 +- .../bindings/pwm/nxp,pca9685-pwm.txt | 2 +- .../devicetree/bindings/pwm/pwm-bcm2835.txt | 2 +- .../devicetree/bindings/pwm/pwm-berlin.txt | 2 +- .../devicetree/bindings/pwm/pwm-fsl-ftm.txt | 2 +- .../devicetree/bindings/pwm/pwm-hibvt.txt | 2 +- .../devicetree/bindings/pwm/pwm-lp3943.txt | 2 +- .../devicetree/bindings/pwm/pwm-mediatek.txt | 2 +- .../devicetree/bindings/pwm/pwm-meson.txt | 2 +- .../devicetree/bindings/pwm/pwm-mtk-disp.txt | 2 +- .../bindings/pwm/pwm-omap-dmtimer.txt | 2 +- .../devicetree/bindings/pwm/pwm-rockchip.txt | 2 +- .../devicetree/bindings/pwm/pwm-sifive.txt | 2 +- .../devicetree/bindings/pwm/pwm-stm32-lp.txt | 2 +- .../devicetree/bindings/pwm/pwm-stm32.txt | 2 +- .../devicetree/bindings/pwm/pwm-tiecap.txt | 2 +- .../devicetree/bindings/pwm/pwm-tiehrpwm.txt | 2 +- .../devicetree/bindings/pwm/pwm-zx.txt | 2 +- Documentation/devicetree/bindings/pwm/pwm.txt | 11 +------ .../devicetree/bindings/pwm/pwm.yaml | 29 +++++++++++++++++++ .../bindings/pwm/renesas,pwm-rcar.yaml | 2 +- .../bindings/pwm/renesas,tpu-pwm.yaml | 2 +- .../devicetree/bindings/pwm/spear-pwm.txt | 2 +- .../devicetree/bindings/pwm/st,stmpe-pwm.txt | 2 +- .../devicetree/bindings/pwm/ti,twl-pwm.txt | 2 +- .../devicetree/bindings/pwm/ti,twl-pwmled.txt | 2 +- .../devicetree/bindings/pwm/vt8500-pwm.txt | 2 +- .../devicetree/bindings/timer/ingenic,tcu.txt | 2 +- 40 files changed, 68 insertions(+), 48 deletions(-) create mode 100644 Documentation/devicetree/bindings/pwm/pwm.yaml
