From 1e8e9bad2db38e93c3bc9f4b6238b3d8be99e469 Mon Sep 17 00:00:00 2001 From: Thomas Chou Date: Fri, 30 Apr 2010 11:34:15 +0800 Subject: nios2: add gpio support to nios2-generic board This patch adds gpio support of Altera PIO component to the nios2-generic board. Though it drives only gpio_led at the moment, it supports bidirectional port to control bit-banging I2C, NAND flash busy status or button switches, etc. Signed-off-by: Thomas Chou Tested-by: Ian Abbott Signed-off-by: Scott McNutt --- include/configs/nios2-generic.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'include/configs/nios2-generic.h') diff --git a/include/configs/nios2-generic.h b/include/configs/nios2-generic.h index e83e1e391e..e4bf57b755 100644 --- a/include/configs/nios2-generic.h +++ b/include/configs/nios2-generic.h @@ -63,10 +63,10 @@ * STATUS LED */ #define CONFIG_STATUS_LED /* Enable status driver */ -#define CONFIG_EPLED /* Enable LED PIO driver */ -#define CONFIG_SYS_LEDPIO_ADDR LED_PIO_BASE +#define CONFIG_GPIO_LED /* Enable GPIO LED driver */ +#define CONFIG_GPIO /* Enable GPIO driver */ -#define STATUS_LED_BIT 1 /* Bit-0 on PIO */ +#define STATUS_LED_BIT 0 /* Bit-0 on GPIO */ #define STATUS_LED_STATE 1 /* Blinking */ #define STATUS_LED_PERIOD (500 / CONFIG_SYS_NIOS_TMRMS) /* 500 msec */ -- cgit v1.2.1
