If anyone has any objections, please let me know. ------------------ From: Matthias Schiffer [ Upstream commit 1e0d75258bd09323cb452655549e03975992b29e ] As described in AM335x Errata Advisory 1.0.42, WKUP_DEBUGSS_CLKCTRL can't be disabled - the clock module will just be stuck in transitioning state forever, resulting in the following warning message after the wait loop times out: l3-aon-clkctrl:0000:0: failed to disable Just add the clock to enable_init_clks, so no attempt is made to disable it.
