ARM: dts: am43x-clock: add tbclk data for ehrpwm
We need "tbclk" clock data for the functioning of ehrpwm module. Hence, populating the required clock information in clock dts file. Signed-off-by: Sourav Poddar <sourav.poddar@ti.com> Acked-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tero Kristo <t-kristo@ti.com>
