From 08f496bbdedd00c3850a36174d4c00c47355225a Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 29 Sep 2015 15:01:08 +0100 Subject: clk: ti: fix dual-registration of uart4_ick commit 19e79687de22f23bcfb5e79cce3daba20af228d1 upstream. On the OMAP AM3517 platform the uart4_ick gets registered twice, causing any power management to /dev/ttyO3 to fail when trying to wake the device up. This solves the following oops: [] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa09e008 [] PC is at serial_omap_pm+0x48/0x15c [] LR is at _raw_spin_unlock_irqrestore+0x30/0x5c Fixes: aafd900cab87 ("CLK: TI: add omap3 clock init file") Cc: mturquette@baylibre.com Cc: sboyd@codeaurora.org Cc: linux-clk@vger.kernel.org Cc: linux-omap@vger.kernel.org Cc: linux-kernel@lists.codethink.co.uk Signed-off-by: Ben Dooks Signed-off-by: Tero Kristo Signed-off-by: Greg Kroah-Hartman --- drivers/clk/ti/clk-3xxx.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/clk/ti/clk-3xxx.c b/drivers/clk/ti/clk-3xxx.c index 757636d166cf..4ab28cfb8d2a 100644 --- a/drivers/clk/ti/clk-3xxx.c +++ b/drivers/clk/ti/clk-3xxx.c @@ -163,7 +163,6 @@ static struct ti_dt_clk omap3xxx_clks[] = { DT_CLK(NULL, "gpio2_ick", "gpio2_ick"), DT_CLK(NULL, "wdt3_ick", "wdt3_ick"), DT_CLK(NULL, "uart3_ick", "uart3_ick"), - DT_CLK(NULL, "uart4_ick", "uart4_ick"), DT_CLK(NULL, "gpt9_ick", "gpt9_ick"), DT_CLK(NULL, "gpt8_ick", "gpt8_ick"), DT_CLK(NULL, "gpt7_ick", "gpt7_ick"), @@ -308,6 +307,7 @@ static struct ti_dt_clk am35xx_clks[] = { static struct ti_dt_clk omap36xx_clks[] = { DT_CLK(NULL, "omap_192m_alwon_fck", "omap_192m_alwon_fck"), DT_CLK(NULL, "uart4_fck", "uart4_fck"), + DT_CLK(NULL, "uart4_ick", "uart4_ick"), { .node_name = NULL }, }; -- cgit v1.2.3
