Subject: [PATCH] ARM: OMAP4: Fix twd_local_timer_register regression
Date: Fri, 12 Oct 2012 09:51:49 -0700 [thread overview]
Message-ID: <20121012165149.GE30339@atomide.com> (raw)
Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal)
changed the interrupts to allow enabling sparse IRQ, but
accidentally added the omap3 INTC base to the local IRQ.
This causes the following:
twd: can't register interrupt 45 (-22)
twd_local_timer_register failed -22
The right fix is to not add any base, as it is a local
timer. For the OMAP44XX_IRQ_LOCALWDT we had defined earlier
there are no users, so no need to fix that.
