Subject: [PATCH 03/22] clk: sunxi: add "pll6" to sun6i protected clock list
Date: Fri, 23 May 2014 15:51:06 +0800 [thread overview]
Message-ID: <1400831485-28576-4-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1400831485-28576-1-git-send-email-wens@csie.org>
PLL6 is used by some important but undocumented module, most likely
memory related, such as mbus or the actual memory controller. As we
do not have a driver for that, add pll6 to the list of protected
clocks, so that it won't be disabled and leave us with a non-responsive
system.
