The gpio driver needs a hack -at 2 places to make the different register layout of the GPIO3 work properly -with the driver. Before only GPIO0-2 were supported. As the GPIO number scheme -clashes with the new size, we also move the other gpio chips to new offsets. - -Signed-off-by: John Crispin <blogic@openwrt.org> -Signed-off-by: Thomas Langer <thomas.langer@lantiq.com> ---- - .../mips/include/asm/mach-lantiq/xway/lantiq_soc.h | 2 + - arch/mips/lantiq/xway/devices.c | 3 + - arch/mips/lantiq/xway/gpio.c | 84 ++++++++++++++++---- - arch/mips/lantiq/xway/gpio_ebu.c | 3 +- - arch/mips/lantiq/xway/gpio_stp.c | 3 +- - 5 files changed, 75 insertions(+), 20 deletions(-) - ---- a/arch/mips/include/asm/mach-lantiq/xway/lantiq_soc.h -+++ b/arch/mips/include/asm/mach-lantiq/xway/lantiq_soc.h -@@ -126,7 +126,9 @@ - #define LTQ_GPIO0_BASE_ADDR 0x1E100B10 - #define LTQ_GPIO1_BASE_ADDR 0x1E100B40 - #define LTQ_GPIO2_BASE_ADDR 0x1E100B70 -+#define LTQ_GPIO3_BASE_ADDR 0x1E100BA0 - #define LTQ_GPIO_SIZE 0x30 -+#define LTQ_GPIO3_SIZE 0x10 - - /* SSC */ - #define LTQ_SSC_BASE_ADDR 0x1e100800 ---- a/arch/mips/lantiq/xway/devices.c -+++ b/arch/mips/lantiq/xway/devices.c -@@ -34,6 +34,7 @@ static struct resource ltq_gpio_resource - MEM_RES("gpio0", LTQ_GPIO0_BASE_ADDR, LTQ_GPIO_SIZE), - MEM_RES("gpio1", LTQ_GPIO1_BASE_ADDR, LTQ_GPIO_SIZE), - MEM_RES("gpio2", LTQ_GPIO2_BASE_ADDR, LTQ_GPIO_SIZE), -+ MEM_RES("gpio3", LTQ_GPIO3_BASE_ADDR, LTQ_GPIO3_SIZE), - };
