The IRQ pin, SYS_NIRQ is dedicated connection between the AM3517 and the TPS65910 PMU. To handle the PMU IRQs, mux configuration is required. Platform data configuration: .IRQ number : SYS_NIRQ (M_IRQ_7) .External clock source : external 32KHz clock is connected Signed-off-by: Milo(Woogyom) Kim --- arch/arm/mach-omap2/board-am3517crane.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) diff --git a/arch/arm/mach-omap2/board-am3517crane.c b/arch/arm/mach-omap2/board-am3517crane.c index 37646e5..82805de 100644 --- a/arch/arm/mach-omap2/board-am3517crane.c +++ b/arch/arm/mach-omap2/board-am3517crane.c @@ -20,6 +20,7 @@ #include #include #include +#include #include #include #include @@ -41,6 +42,7 @@ #ifdef CONFIG_OMAP_MUX static struct omap_board_mux board_mux[] __initdata = { + OMAP3_MUX(SYS_NIRQ, OMAP_MUX_MODE0 | OMAP_PIN_INPUT_PULLUP), { .reg_offset = OMAP_MUX_TERMINATOR }, }; #endif @@ -86,6 +88,24 @@ static struct mtd_partition crane_nand_partitions[] = { }, }; +static struct tps65910_board tps65910_pdata = { + .irq = 7 + OMAP_INTC_START, + .en_ck32k_xtal = true, +}; + +static struct i2c_board_info __initdata tps65910_board_info[] = { + { + I2C_BOARD_INFO("tps65910", 0x2d), + .platform_data = &tps65910_pdata, + }, +}; + +static void __init am3517_crane_i2c_init(void) +{ + omap_register_i2c_bus(1, 2600, tps65910_board_info, + ARRAY_SIZE(tps65910_board_info)); +} + static void __init am3517_crane_init(void) { int ret; @@ -96,6 +116,7 @@ static void __init am3517_crane_init(void) board_nand_init(crane_nand_partitions, ARRAY_SIZE(crane_nand_partitions), 0, NAND_BUSWIDTH_16, NULL); + am3517_crane_i2c_init(); /* Configure GPIO for EHCI port */ if (omap_mux_init_gpio(GPIO_USB_NRESET, OMAP_PIN_OUTPUT)) {
