Subject: [RFC PATCH 01/18] OMAP1: GPIO: Fix mpuio_init() call
Date: Fri, 22 Apr 2011 16:38:15 +0530	[thread overview]
Message-ID: <1303470512-19671-2-git-send-email-charu@ti.com> (raw)
In-Reply-To: <1303470512-19671-1-git-send-email-charu@ti.com>

In OMAP1 GPIO, MPUIO bank's initialization is called as part of
omap_gpio_sysinit() which is an "arch_initcall". mpuio_init()
relies on the gpio_bank pointer of MPUIO bank whose memory is
allocated only during omap_gpio_probe(). Hence move mpuio_init()
call as part of probe after the gpio_bank pointer is initialized.
