gt911_ts ============ GT911 Touch Screen Driver For Rockchip How to configure in your device: 1. Clone into drivers/input/touchscreen/gt9xx 2. Add in drivers/input/touchscreen/Kconfig ``` config TOUCHSCREEN_GT9XX_IIC tristate "GT9xx_IIC based touchscreens" depends on I2C2_RK30 source "drivers/input/touchscreen/gt9xx/Kconfig" ``` 3. Add in drivers/input/touchscreen/Makefile ``` obj-$(CONFIG_TOUCHSCREEN_GT9XX_IIC) += gt9xx/ ``` 4. Add platform structure to your arch/arm/plat-rk/include/plat/board.h file ``` struct goodix_9xx_platform_data { int model; unsigned gpio_shutdown; unsigned gpio_irq; unsigned gpio_reset; bool irq_edge; /* 0:rising edge, 1:falling edge */ int xmax; int ymax; int config_info_len; u8 *config_info; int (*init_platform_hw)(void); int (*exit_platform_hw)(void); bool send_config; // Sends config_info, instead ROM's confing bool custom_config; // Sends xmax, ymax, irq edge instead stuff in config bool mirrorxy; bool swap_xy; }; ``` 5. Setup touchpanel config in your board file. Make sure you replace goodix_config data with yours! ``` #if defined(CONFIG_TOUCHSCREEN_GT9XX_IIC) #define TOUCH_RESET_PIN RK30_PIN4_PD0 #define TOUCH_INT_PIN RK30_PIN4_PC2 #define TOUCH_PWR_PIN INVALID_GPIO int goodix_init_platform_hw(void) { int ret; if (TOUCH_PWR_PIN != INVALID_GPIO) { ret = gpio_request(TOUCH_PWR_PIN, "goodix power pin"); if (ret != 0) { gpio_free(TOUCH_PWR_PIN); printk("goodix power error\n"); return -EIO; } gpio_direction_output(TOUCH_PWR_PIN, 0); gpio_set_value(TOUCH_PWR_PIN, GPIO_LOW); msleep(100); } if (TOUCH_INT_PIN != INVALID_GPIO) { ret = gpio_request(TOUCH_INT_PIN, "goodix irq pin"); if (ret != 0) { gpio_free(TOUCH_INT_PIN); printk("goodix irq error\n"); return -EIO; } } if (TOUCH_RESET_PIN != INVALID_GPIO) { ret = gpio_request(TOUCH_RESET_PIN, "goodix reset pin"); if (ret != 0) { gpio_free(TOUCH_RESET_PIN); printk("goodix gpio_request error\n"); return -EIO; } gpio_direction_output(TOUCH_RESET_PIN, 0); gpio_set_value(TOUCH_RESET_PIN,GPIO_HIGH); msleep(50); gpio_set_value(TOUCH_RESET_PIN,GPIO_LOW); msleep(50); gpio_set_value(TOUCH_RESET_PIN,GPIO_HIGH); msleep(50); } return 0; } void goodix_exit_platform_hw(void) { gpio_free(TOUCH_RESET_PIN); gpio_free(TOUCH_INT_PIN); } u8 goodix_config[] = { 0x50,0x00,0x04,0x00,0x03,0x05,0x35,0x00,0x03,0x0D,0x14,0x0F,0x5F, 0x55,0x03,0x05,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x18,0x1A,0x1E, 0x14,0x8C,0x27,0x0E,0x1D,0x23,0x04,0x0D,0x00,0x00,0x00,0x9B,0x02, 0x35,0x00,0x00,0x00,0x00,0x00,0x03,0x***,0x32,0x00,0x00,0x00,0x32, 0xFA,0x01,0x00,0x00,0x08,0x00,0x00,0x7B,0x15,0x15,0x7B,0x15,0x1D, 0x4B,0x1D,0x23,0x4B,0x1D,0x29,0x33,0x21,0x39,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x02,0x04,0x06,0x08,0x0A, 0x0C,0x0E,0x10,0x12,0x14,0x16,0x18,0x1A,0x1C,0xFF,0xFF,0xFF,0xFF, 0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0x00, 0x02,0x04,0x06,0x08,0x0A,0x0C,0x0F,0x10,0x12,0x13,0x14,0x16,0x18, 0x1C,0x1D,0x1E,0x1F,0x20,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF, 0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF, 0xFF,0xFF,0x7E,0x01 }; struct goodix_9xx_platform_data goodix_info = { .model = 9110, .irq_edge = 1, /* 0:rising edge, 1:falling edge */ .gpio_shutdown = INVALID_GPIO, .gpio_irq = TOUCH_INT_PIN, .gpio_reset = TOUCH_RESET_PIN, .swap_xy = 1, .mirrorxy = 0, .xmax = 1024, .ymax = 768, .send_config = 1, .custom_config = 1, .config_info_len = ARRAY_SIZE(goodix_config), .config_info = goodix_config, .init_platform_hw = goodix_init_platform_hw, .exit_platform_hw = goodix_exit_platform_hw, }; #endif //... #ifdef CONFIG_I2C2_RK30 static struct i2c_board_info __initdata i2c2_info[] = { #if defined (CONFIG_TOUCHSCREEN_GT9XX_IIC) { .type = "Goodix-TS", .addr = 0x5d, .flags = 0, .irq = TOUCH_INT_PIN, .platform_data = &goodix_info, }, #endif ```
