From 03e128ca35e5da22e9e65ec8ab158ec0e905fdea Mon Sep 17 00:00:00 2001 From: Charulatha V Date: Thu, 5 May 2011 19:58:01 +0530 Subject: gpio/omap: remove dependency on gpio_bank_count The gpio_bank_count is the count of number of GPIO devices in a SoC. Remove this dependency from the driver by using list. Also remove the dependency on array of pointers to gpio_bank struct of all GPIO devices.

Identify the same using a flag and remove all METHOD_* macros. mpuio_init() function is defined under #ifdefs. It is required only in case of MPUIO bank type and only when PM operations are supported by it. This is applicable only in case of OMAP16xx SoC's MPUIO GPIO bank type. For all the other cases it is a dummy function. Hence clean up the same and remove all the OMAP SoC specific #ifdefs.

But, in OMAP7xx, it is wrongly initialised to 32. Fix this.
