Subject: ARM: dts: imx6sx-sdb: Use #pwm-cells = <3> for imx27-pwm device
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=340bef9852edd63e2bb356b0f52db8c7c17f59fc;p=linux.git

ARM: dts: imx6sx-sdb: Use #pwm-cells = <3> for imx27-pwm device

The binding dictates using 3 pwm-cells. Adhere to that.

This fixes the following dtbs_check warnings:

	arch/arm/boot/dts/nxp/imx/imx6sx-sdb-reva.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected
		from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml#
	arch/arm/boot/dts/nxp/imx/imx6sx-sdb-sai.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected
		from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml#
	arch/arm/boot/dts/nxp/imx/imx6sx-sdb.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected
		from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml#
	arch/arm/boot/dts/nxp/imx/imx6sx-sdb-mqs.dtb: pwm@2088000: #pwm-cells:0:0: 3 was expected
		from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml#

There is no need for an explicit status = "okay" in the pwm node as
the soc dtsi doesn't disable this device. Drop this property, too.
