Subject: regression: Clock changes in next-20141205 break at least omap4
Date: Fri, 5 Dec 2014 08:55:39 -0800 [thread overview]
Message-ID: <20141205165539.GA30437@atomide.com> (raw)
Hi,
Looks like commit 646cafc6aa4d ("clk: Change clk_ops->determine_rate
to return a clk_hw as the best parent") breaks booting at least for
omap4.
Below is the output from omap4-sdp with DEBUG_LL and earlyprintk
enabled.
Regards,
Tony
