From 87bd05d78f0f5765f3d3e1517c76794c82dab7cc Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 21 Jun 2013 18:54:25 +0800 Subject: ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5 The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs. These SoCs have different gpio count but currently omap_gpio driver uses hard coded 192 which is wrong. This patch fixes this issue by: 1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h. 2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5. Thanks for Lubomir Popov to provide valuable comments to fix this issue.
