From f6ae1ca05839f92b103aaa0743d1d0012ba9773d Mon Sep 17 00:00:00 2001 From: Akshay Saraswat Date: Tue, 13 May 2014 10:30:14 +0530 Subject: S5P: Exynos: Add GPIO pin numbering and rename definitions This patch includes following changes : * Adds gpio pin numbering support for EXYNOS SOCs. To have consistent 0..n-1 GPIO numbering the banks are divided into different parts where ever they have holes in them. * Rename GPIO definitions from GPIO_... to S5P_GPIO_... These changes were done to enable cmd_gpio for EXYNOS and cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence getting a error during compilation. * Adds support for name to gpio conversion in s5p_gpio to enable gpio command EXYNOS SoCs. Function has been added to asm/gpio.h to decode the input gpio name to gpio number.
