But with commit 58bfbea5b1c68 ("ARM: dts: am437x/am33xx: Remove hwmod entries for ECAP and EPWM nodes") dropped support for all ti,hwmod for ehrpwm, but missed deprecating ti,am33xx-ehrpwm compatible. So drop ti,am33xx-ehrpwm from DT as it is no longer needed. ti-ehrpwn driver still support ti,am33xx-ehrpwm in order to maintain backward compatibility.
