From mboxrd@z Thu Jan 1 00:00:00 1970 From: bgolaszewski@baylibre.com (Bartosz Golaszewski) Date: Thu, 1 Dec 2016 18:15:14 +0100 Subject: [PATCH 1/3] ARM: da850: fix infinite loop in clk_set_rate() In-Reply-To: <1480612516-18853-1-git-send-email-bgolaszewski@baylibre.com> References: <1480612516-18853-1-git-send-email-bgolaszewski@baylibre.com> Message-ID: <1480612516-18853-2-git-send-email-bgolaszewski@baylibre.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The aemif clock is added twice to the lookup table in da850.c. This breaks the children list of pll0_sysclk3 as we're using the same list links in struct clk. When calling clk_set_rate(), we get stuck in propagate_rate(). Simply add the clock once, but specify both the con_id and dev_id in the lookup entry.
