Subject: ARM: dts: am33xx-clocks: Fix ehrpwm tbclk data on am33xx
From: Vignesh R <vigneshr@xxxxxx>
commit 6e22616eba7e25fac5aa6cb6563471afa1815ec2 upstream.
ehrpwm tbclk is wrongly modelled as deriving from dpll_per_m2_ck.
The TRM says tbclk is derived from SYSCLKOUT. SYSCLKOUT nothing but the
functional clock of pwmss (l4ls_gclk).
Fix this by changing source of ehrpwmx_tbclk to l4ls_gclk.
