A grep \&pwm arch/arm/boot/dts/imx6* yields:
* imx6dl-aristainetos_4.dts - needs pwm1
* imx6dl-aristainetos_7.dts - needs pwm3
imx6dl-riotboard.dts - already enables pwm1-4
imx6dl-tx6dl-comtft.dts - already enables pwm2
imx6dl-tx6u-801x.dts - pwm2 enabled in imx6qdl-tx6.dtsi
imx6dl-tx6u-811x.dts - already enables pwm1, pwm2 enabled in imx6qdl-tx6.dtsi
* imx6qdl-cubox-i.dtsi - needs pwm1
imx6qdl-gw52xx.dtsi - already enables pwm4
imx6qdl-gw53xx.dtsi - already enables pwm4
imx6qdl-gw54xx.dtsi - already enables pwm4
imx6qdl-nitrogen6x.dtsi - already enables pwm1, 3, and 4
imx6qdl-sabreauto.dtsi - already enables pwm3
imx6qdl-sabrelite.dtsi - already enables pwm1, 3, and 4
imx6qdl-sabresd.dtsi - already enables pwm1
imx6q-tx6q-1010-comtft.dts - pwm2 enabled in imx6qdl-tx6.dtsi
imx6q-tx6q-1010.dts - pwm2 enabled in imx6qdl-tx6.dtsi
imx6q-tx6q-1020-comtft.dts - pwm2 enabled in imx6qdl-tx6.dtsi
imx6q-tx6q-1020.dts - pwm2 enabled in imx6qdl-tx6.dtsi
imx6q-tx6q-1110.dts - enables pwm1, pwm2 enabled in imx6qdl-tx6.dtsi
imx6sl-evk.dts - enables pwm1
imx6sx-sdb.dts - enables pwm3
Did I miss anything? I'll send a patch for those three.
regards
Philipp
