From 7efa7cc5b807cb840c62b5bf54bf47181c9b95a6 Mon Sep 17 00:00:00 2001 From: Koen Kooi Date: Mon, 30 Mar 2009 15:21:37 +0200 Subject: [PATCH v2] ARM: OMAP: board-ldp: add regulator info to get the microSD slot working again The ldp board was left behind when other boards got updated. The ldp info was copied from the beagleboard board file and s/beagle/ldp/g Changes since v1: * dropped vsim portion since only 4 pins are hooked up Signed-off-by: Koen Kooi --- arch/arm/mach-omap2/board-ldp.c | 32 ++++++++++++++++++++++++++++++++ 1 files changed, 32 insertions(+), 0 deletions(-) diff --git a/arch/arm/mach-omap2/board-ldp.c b/arch/arm/mach-omap2/board-ldp.c index 30926b0..19a5c15 100644 --- a/arch/arm/mach-omap2/board-ldp.c +++ b/arch/arm/mach-omap2/board-ldp.c @@ -22,6 +22,7 @@ #include #include #include +#include #include #include @@ -450,7 +451,16 @@ static struct twl4030_script *twl4030_scripts[] __initdata = { &wrst_script, }; +static const struct twl4030_resconfig ldp_resconfig[] = { + /* disable regulators that u-boot left enabled; the + * devices' drivers should be managing these. + */ + { .resource = RES_VMMC1, }, + { 0, }, +}; + static struct twl4030_power_data sdp3430_t2scripts_data __initdata = { + .resource_config = ldp_resconfig, .scripts = twl4030_scripts, .size = ARRAY_SIZE(twl4030_scripts), }; @@ -474,6 +484,25 @@ static struct twl4030_madc_platform_data ldp_madc_data = { .irq_line = 1, }; +static struct regulator_consumer_supply ldp_vmmc1_supply = { + .supply = "vmmc", +}; + +/* VMMC1 for MMC1 pins CMD, CLK, DAT0..DAT3 (20 mA, plus card == max 220 mA) */ +static struct regulator_init_data ldp_vmmc1 = { + .constraints = { + .min_uV = 1850000, + .max_uV = 3150000, + .valid_modes_mask = REGULATOR_MODE_NORMAL + | REGULATOR_MODE_STANDBY, + .valid_ops_mask = REGULATOR_CHANGE_VOLTAGE + | REGULATOR_CHANGE_MODE + | REGULATOR_CHANGE_STATUS, + }, + .num_consumer_supplies = 1, + .consumer_supplies = &ldp_vmmc1_supply, +}; + static struct twl4030_platform_data ldp_twldata = { .irq_base = TWL4030_IRQ_BASE, .irq_end = TWL4030_IRQ_END, @@ -483,6 +512,7 @@ static struct twl4030_platform_data ldp_twldata = { .madc = &ldp_madc_data, .usb = &ldp_usb_data, .power = &sdp3430_t2scripts_data, + .vmmc1 = &ldp_vmmc1, .gpio = &ldp_gpio_data, .keypad = &ldp_kp_twl4030_data, }; @@ -530,6 +560,8 @@ static void __init omap_ldp_init(void) omap_serial_init(); usb_musb_init(); twl4030_mmc_init(mmc); + /* link regulators to MMC adapters */ + ldp_vmmc1_supply.dev = mmc[0].dev; } static void __init omap_ldp_map_io(void) -- 1.6.2
