From mboxrd@z Thu Jan 1 00:00:00 1970 From: tony@atomide.com (Tony Lindgren) Date: Fri, 13 Aug 2010 11:01:56 +0300 Subject: [PATCH 2/6] OMAP3: Fix a cpu type check problem In-Reply-To: <20100813080034.18750.15410.stgit@baageli.muru.com> References: <20100813080034.18750.15410.stgit@baageli.muru.com> Message-ID: <20100813080156.18750.74200.stgit@baageli.muru.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: stanley.miao cpu_is_omap3517() and cpu_is_omap3505() are the subgroups of cpu_is_omap34xx(), so we should check cpu_is_omap3517() and cpu_is_omap3505() first, then check cpu_is_omap34xx(). Otherwise, All AM35XX (Sitara) clocks do not get registered and device drivers (ti_hecc, etc...) that depend on those clocks are failing to get the clock and end up with non working device.
