Subject: [PATCH] Fix i8042 PS/2 mouse on ARM
Date: Thu, 4 Mar 2004 19:22:57 +0000 [thread overview]
Message-ID: <20040304192257.A13227@flint.arm.linux.org.uk> (raw)
Vojtech,
This patch is required on ARM so that we pick up the correct AUX
interrupt number. Some machines (eg, NetWinders) use IRQ5 instead
of IRQ12 for the PS/2 mouse.
Please comment, and let me know if you're happy to apply it, or
whether you're happy for me to do so.
Thanks.
