From 1c1b6ffce5737d764cc474b9bd6677bb9a344094 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Wed, 24 Sep 2008 23:36:23 +0200 Subject: mfd: provide and use setup hook for tc6393xb Instead of using bitfields for initial gpio setup, provide generic setup/teardown hooks that can be used to set the gpio states, register child devices, etc. Signed-off-by: Dmitry Baryshkov Signed-off-by: Samuel Ortiz --- arch/arm/mach-pxa/include/mach/tosa.h | 2 -- arch/arm/mach-pxa/tosa.c | 35 +++++++++++++++++++++++++++++------ 2 files changed, 29 insertions(+), 8 deletions(-) (limited to 'arch/arm') diff --git a/arch/arm/mach-pxa/include/mach/tosa.h b/arch/arm/mach-pxa/include/mach/tosa.h index a72803f0461..8bce6d8615b 100644 --- a/arch/arm/mach-pxa/include/mach/tosa.h +++ b/arch/arm/mach-pxa/include/mach/tosa.h @@ -59,8 +59,6 @@ * TC6393XB GPIOs */ #define TOSA_TC6393XB_GPIO_BASE (NR_BUILTIN_GPIO + 2 * 12) -#define TOSA_TC6393XB_GPIO(i) (TOSA_TC6393XB_GPIO_BASE + (i)) -#define TOSA_TC6393XB_GPIO_BIT(gpio) (1 << (gpio - TOSA_TC6393XB_GPIO_BASE)) #define TOSA_GPIO_TG_ON (TOSA_TC6393XB_GPIO_BASE + 0) #define TOSA_GPIO_L_MUTE (TOSA_TC6393XB_GPIO_BASE + 1) diff --git a/arch/arm/mach-pxa/tosa.c b/arch/arm/mach-pxa/tosa.c index 130e37e4ebd..fac846b0d07 100644 --- a/arch/arm/mach-pxa/tosa.c +++ b/arch/arm/mach-pxa/tosa.c @@ -706,16 +706,39 @@ static struct tmio_nand_data tosa_tc6393xb_nand_config = { .badblock_pattern = &tosa_tc6393xb_nand_bbt, }; -static struct tc6393xb_platform_data tosa_tc6393xb_setup = { +static int tosa_tc6393xb_setup(struct platform_device *dev) +{ + int rc; + + rc = gpio_request(TOSA_GPIO_CARD_VCC_ON, "CARD_VCC_ON"); + if (rc) + goto err_req; + + rc = gpio_direction_output(TOSA_GPIO_CARD_VCC_ON, 1); + if (rc) + goto err_dir; + + return rc; + +err_dir: + gpio_free(TOSA_GPIO_CARD_VCC_ON); +err_req: + return rc; +} + +static void tosa_tc6393xb_teardown(struct platform_device *dev) +{ + gpio_free(TOSA_GPIO_CARD_VCC_ON); +} + +static struct tc6393xb_platform_data tosa_tc6393xb_data = { .scr_pll2cr = 0x0cc1, .scr_gper = 0x3300, - .scr_gpo_dsr = - TOSA_TC6393XB_GPIO_BIT(TOSA_GPIO_CARD_VCC_ON), - .scr_gpo_doecr = - TOSA_TC6393XB_GPIO_BIT(TOSA_GPIO_CARD_VCC_ON), .irq_base = IRQ_BOARD_START, .gpio_base = TOSA_TC6393XB_GPIO_BASE, + .setup = tosa_tc6393xb_setup, + .teardown = tosa_tc6393xb_teardown, .enable = tosa_tc6393xb_enable, .disable = tosa_tc6393xb_disable, @@ -730,7 +753,7 @@ static struct platform_device tc6393xb_device = { .name = "tc6393xb", .id = -1, .dev = { - .platform_data = &tosa_tc6393xb_setup, + .platform_data = &tosa_tc6393xb_data, }, .num_resources = ARRAY_SIZE(tc6393xb_resources), .resource = tc6393xb_resources, -- cgit v1.2.3
