This patch adds support for gpio pin numbering support on EXYNOS5250 To have consistent 0..n-1 GPIO numbering the banks are divided into different parts where ever they have holes in them.
Signed-off-by: Leela Krishna Amudala l.krishna@samsung.com Signed-off-by: Rajeshwari Shinde rajeshwari.s@samsung.com --- Changes in V2: - none. Changes in V3: - none. Changes in V4: - To have consistent 0..n-1 GPIO numbering the banks are divided into different parts where ever they have holes in them. - Combined previous patch 1 and 2 into single patch. arch/arm/cpu/armv7/exynos/pinmux.c | 148 +++++------- arch/arm/include/asm/arch-exynos/cpu.h | 10 +- arch/arm/include/asm/arch-exynos/gpio.h | 376 ++++++++++++++++++++++++++++++- board/samsung/smdk5250/smdk5250.c | 24 +-- drivers/gpio/s5p_gpio.c | 65 ++++++- 5 files changed, 508 insertions(+), 115 deletions(-)
