Hi! Upstream linux kernel has already driver for lis3lv02d accelerometer in drivers/misc/lis3lv02d. So now can be added also platform support for nokia rx51. Patch exists for long time in meego obs repository: https://build.pub.meego.com/package/view_file?file=linux-2.6-omap-rx51-Platform-support-for-lis3lv02d-acceleromet.patch&package=kernel-adaptation-n900&project�3AAdaptation%3AN900 It is possible to include this patch to upstream kernel? diff --git a/arch/arm/mach-omap2/board-rx51-peripherals.c b/arch/arm/mach-omap2/board-rx51-peripherals.c index d87ee06..a49801f 100644 --- a/arch/arm/mach-omap2/board-rx51-peripherals.c +++ b/arch/arm/mach-omap2/board-rx51-peripherals.c @@ -44,6 +44,7 @@ #include <linux/leds-lp5523.h> #include <../drivers/staging/iio/light/tsl2563.h> +#include <linux/lis3lv02d.h> #include "mux.h" #include "hsmmc.h" @@ -63,6 +64,9 @@ #define RX51_TSC2005_RESET_GPIO 104 #define RX51_TSC2005_IRQ_GPIO 100 +#define LIS302_IRQ1_GPIO 181 +#define LIS302_IRQ2_GPIO 180 /* Not yet in use */ + /* list all spi devices here */ enum { RX51_SPI_WL1251, @@ -73,6 +77,77 @@ enum { static struct wl12xx_platform_data wl1251_pdata; static struct tsc2005_platform_data tsc2005_pdata; +#if defined(CONFIG_SENSORS_LIS3_I2C) || defined(CONFIG_SENSORS_LIS3_I2C_MODULE) +static int lis302_setup(void) +{ + int err; + int irq1 = LIS302_IRQ1_GPIO; + int irq2 = LIS302_IRQ2_GPIO; + + /* gpio for interrupt pin 1 */ + err = gpio_request(irq1, "lis3lv02dl_irq1"); + if (err) { + printk(KERN_ERR "lis3lv02dl: gpio request failed\n"); + goto out; + } + + /* gpio for interrupt pin 2 */ + err = gpio_request(irq2, "lis3lv02dl_irq2"); + if (err) { + gpio_free(irq1); + printk(KERN_ERR "lis3lv02dl: gpio request failed\n"); + goto out; + } + + gpio_direction_input(irq1); + gpio_direction_input(irq2); + +out: + return err; +} + +static int lis302_release(void) +{ + gpio_free(LIS302_IRQ1_GPIO); + gpio_free(LIS302_IRQ2_GPIO); + + return 0; +} + +static struct lis3lv02d_platform_data rx51_lis3lv02d_data = { + .click_flags = LIS3_CLICK_SINGLE_X | LIS3_CLICK_SINGLE_Y | + LIS3_CLICK_SINGLE_Z, + /* Limits are 0.5g * value */ + .click_thresh_x = 8, + .click_thresh_y = 8, + .click_thresh_z = 10, + /* Click must be longer than time limit */ + .click_time_limit = 9, + /* Kind of debounce filter */ + .click_latency = 50, + + /* Limits for all axis. millig-value / 18 to get HW values */ + .wakeup_flags = LIS3_WAKEUP_X_HI | LIS3_WAKEUP_Y_HI, + .wakeup_thresh = 800 / 18, + .wakeup_flags2 = LIS3_WAKEUP_Z_HI , + .wakeup_thresh2 = 900 / 18, + + .hipass_ctrl = LIS3_HIPASS1_DISABLE | LIS3_HIPASS2_DISABLE, + + /* Interrupt line 2 for click detection, line 1 for thresholds */ + .irq_cfg = LIS3_IRQ2_CLICK | LIS3_IRQ1_FF_WU_12, + + .axis_x = LIS3_DEV_X, + .axis_y = LIS3_INV_DEV_Y, + .axis_z = LIS3_INV_DEV_Z, + .setup_resources = lis302_setup, + .release_resources = lis302_release, + .st_min_limits = {-32, 3, 3}, + .st_max_limits = {-3, 32, 32}, + .irq2 = OMAP_GPIO_IRQ(LIS302_IRQ2_GPIO), +}; +#endif + #if defined(CONFIG_SENSORS_TSL2563) || defined(CONFIG_SENSORS_TSL2563_MODULE) static struct tsl2563_platform_data rx51_tsl2563_platform_data = { .cover_comp_gain = 16, @@ -950,6 +1025,16 @@ static struct i2c_board_info __initdata rx51_peripherals_i2c_board_info_2[] = { } }; +static struct i2c_board_info __initdata rx51_peripherals_i2c_board_info_3[] = { +#if defined(CONFIG_SENSORS_LIS3_I2C) || defined(CONFIG_SENSORS_LIS3_I2C_MODULE) + { + I2C_BOARD_INFO("lis3lv02d", 0x1d), + .platform_data = &rx51_lis3lv02d_data, + .irq = OMAP_GPIO_IRQ(LIS302_IRQ1_GPIO), + }, +#endif +}; + static int __init rx51_i2c_init(void) { if ((system_rev >= SYSTEM_REV_S_USES_VAUX3 && system_rev < 0x100) || @@ -971,7 +1056,8 @@ static int __init rx51_i2c_init(void) omap_pmic_init(1, 2200, "twl5030", INT_34XX_SYS_NIRQ, &rx51_twldata); omap_register_i2c_bus(2, 100, rx51_peripherals_i2c_board_info_2, ARRAY_SIZE(rx51_peripherals_i2c_board_info_2)); - omap_register_i2c_bus(3, 400, NULL, 0); + omap_register_i2c_bus(3, 400, rx51_peripherals_i2c_board_info_3, + ARRAY_SIZE(rx51_peripherals_i2c_board_info_3)); return 0; } -- Pali Rohár pali.rohar@xxxxxxxxx
