Subject: [PATCH 2/2] ARM: dts: am43xx-clocks: Fix ehrpwm tbclk data on am43xx
Date: Tue, 10 Feb 2015 11:05:42 +0530	[thread overview]
Message-ID: <1423546542-29664-3-git-send-email-vigneshr@ti.com> (raw)
In-Reply-To: <1423546542-29664-1-git-send-email-vigneshr-l0cyMroinI0@public.gmane.org>

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.

Fixes: 4da1c67719f61 ("add tbclk data for ehrpwm")
