From 19b90c7c0fc0d9c9193d38fad180785aa6d7b7e3 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Thu, 5 Aug 2010 18:00:18 +0900 Subject: [PATCH] ARM: S5PV210: Add SDHCI devices for GONI board This patch add support for SDHCI blocks on Samsung Goni board. The following host controllers are defined: 1. Internal MoviNAND device (permanently wired to the controller) 2. Internal WiFI SDIO device (card is activated by power regualor) 3. External MMC/SD socket (card detection is provided by external gpio interrupt) Signed-off-by: Marek Szyprowski Signed-off-by: Kyungmin Park Signed-off-by: Kukjin Kim --- arch/arm/mach-s5pv210/Kconfig | 4 ++++ arch/arm/mach-s5pv210/mach-goni.c | 39 +++++++++++++++++++++++++++++++ 2 files changed, 43 insertions(+) diff --git a/arch/arm/mach-s5pv210/Kconfig b/arch/arm/mach-s5pv210/Kconfig index a392748dffa0..9b84abf1a822 100644 --- a/arch/arm/mach-s5pv210/Kconfig +++ b/arch/arm/mach-s5pv210/Kconfig @@ -74,8 +74,12 @@ config MACH_GONI select CPU_S5PV210 select ARCH_SPARSEMEM_ENABLE select S5PV210_SETUP_FB_24BPP + select S5PV210_SETUP_SDHCI select S3C_DEV_FB select S5PC110_DEV_ONENAND + select S3C_DEV_HSMMC + select S3C_DEV_HSMMC1 + select S3C_DEV_HSMMC2 help Machine support for Samsung GONI board S5PC110(MCP) is one of package option of S5PV210 diff --git a/arch/arm/mach-s5pv210/mach-goni.c b/arch/arm/mach-s5pv210/mach-goni.c index 7b18505e5171..a094b44a43e8 100644 --- a/arch/arm/mach-s5pv210/mach-goni.c +++ b/arch/arm/mach-s5pv210/mach-goni.c @@ -35,6 +35,7 @@ #include #include #include +#include /* Following are default values for UCON, ULCON and UFCON UART registers */ #define S5PV210_UCON_DEFAULT (S3C2410_UCON_TXILEVEL | \ @@ -420,12 +421,47 @@ static void __init goni_pmic_init(void) s3c_gpio_setpull(S5PV210_GPH2(6), S3C_GPIO_PULL_UP); } +/* MoviNAND */ +static struct s3c_sdhci_platdata goni_hsmmc0_data __initdata = { + .max_width = 4, + .cd_type = S3C_SDHCI_CD_PERMANENT, +}; + +/* Wireless LAN */ +static struct s3c_sdhci_platdata goni_hsmmc1_data __initdata = { + .max_width = 4, + .cd_type = S3C_SDHCI_CD_EXTERNAL, + /* ext_cd_{init,cleanup} callbacks will be added later */ +}; + +/* External Flash */ +#define GONI_EXT_FLASH_EN S5PV210_MP05(4) +#define GONI_EXT_FLASH_CD S5PV210_GPH3(4) +static struct s3c_sdhci_platdata goni_hsmmc2_data __initdata = { + .max_width = 4, + .cd_type = S3C_SDHCI_CD_GPIO, + .ext_cd_gpio = GONI_EXT_FLASH_CD, + .ext_cd_gpio_invert = 1, +}; + +static void goni_setup_sdhci(void) +{ + gpio_request(GONI_EXT_FLASH_EN, "FLASH_EN"); + gpio_direction_output(GONI_EXT_FLASH_EN, 1); + + s3c_sdhci0_set_platdata(&goni_hsmmc0_data); + s3c_sdhci1_set_platdata(&goni_hsmmc1_data); + s3c_sdhci2_set_platdata(&goni_hsmmc2_data); +}; static struct platform_device *goni_devices[] __initdata = { &s3c_device_fb, &s5pc110_device_onenand, &goni_i2c_gpio_pmic, &goni_device_gpiokeys, + &s3c_device_hsmmc0, + &s3c_device_hsmmc1, + &s3c_device_hsmmc2, }; static void __init goni_map_io(void) @@ -441,6 +477,9 @@ static void __init goni_machine_init(void) goni_pmic_init(); i2c_register_board_info(AP_I2C_GPIO_PMIC_BUS_4, i2c_gpio_pmic_devs, ARRAY_SIZE(i2c_gpio_pmic_devs)); + /* SDHCI */ + goni_setup_sdhci(); + /* FB */ s3c_fb_set_platdata(&goni_lcd_pdata); -- GitLab
