f6ae1ca058
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. Example: SMDK5420 # gpio set gpa00 Signed-off-by: Leela Krishna Amudala <l.krishna@samsung.com> Signed-off-by: Rajeshwari Shinde <rajeshwari.s@samsung.com> Signed-off-by: Akshay Saraswat <akshay.s@samsung.com> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
