The SpeedLink Vicious And Devine Laplace webcam is using an EM2765 bridge and an OV2640 sensor. It has a built-in microphone (USB standard device class) and provides 3 buttons (snapshot, illumination, mute) and 2 LEDs (capturing/mute and illumination/flash). It is also equipped with an eeprom. The device is available in two colors: white (1ae7:9003) and black (1ae7:9004). For further details see http://linuxtv.org/wiki/index.php/VAD_Laplace. Please note the following limitations that need to be addressed later: - resolution limited to 640x480 (sensor supports 1600x1200) - picture quality needs to be improved - AV-mute button doesn't work yet Signed-off-by: Frank Schäfer <fschaefer.oss@xxxxxxxxxxxxxx> --- drivers/media/usb/em28xx/em28xx-cards.c | 72 +++++++++++++++++++++++++++++++ drivers/media/usb/em28xx/em28xx.h | 1 + 2 Dateien geändert, 73 Zeilen hinzugefügt(+) diff --git a/drivers/media/usb/em28xx/em28xx-cards.c b/drivers/media/usb/em28xx/em28xx-cards.c index ebb112c..6454309 100644 --- a/drivers/media/usb/em28xx/em28xx-cards.c +++ b/drivers/media/usb/em28xx/em28xx-cards.c @@ -412,6 +412,21 @@ static struct em28xx_reg_seq pctv_520e[] = { { -1, -1, -1, -1}, }; +/* 1ae7:9003/9004 SpeedLink Vicious And Devine Laplace webcam + * reg 0x80/0x84: + * GPIO_0: capturing LED, 0=on, 1=off + * GPIO_2: AV mute button, 0=pressed, 1=unpressed + * GPIO 3: illumination button, 0=pressed, 1=unpressed + * GPIO_6: illumination/flash LED, 0=on, 1=off + * reg 0x81/0x85: + * GPIO_7: snapshot button, 0=pressed, 1=unpressed + */ +static struct em28xx_reg_seq speedlink_vad_laplace_reg_seq[] = { + {EM2820_R08_GPIO_CTRL, 0xf7, 0xff, 10}, + {EM2874_R80_GPIO_P0_CTRL, 0xff, 0xb2, 10}, + { -1, -1, -1, -1}, +}; + /* * Button definitions */ @@ -426,6 +441,41 @@ static struct em28xx_button std_snapshot_button[] = { {-1, 0, 0, 0, 0}, }; +static struct em28xx_button speedlink_vad_laplace_buttons[] = { + { + .role = EM28XX_BUTTON_SNAPSHOT, + .reg_r = EM2874_R85_GPIO_P1_STATE, + .mask = 0x80, + .inverted = 1, + }, + { + .role = EM28XX_BUTTON_ILLUMINATION, + .reg_r = EM2874_R84_GPIO_P0_STATE, + .mask = 0x08, + .inverted = 1, + }, + {-1, 0, 0, 0, 0}, +}; + +/* + * LED definitions + */ +static struct em28xx_led speedlink_vad_laplace_leds[] = { + { + .role = EM28XX_LED_ANALOG_CAPTURING, + .gpio_reg = EM2874_R80_GPIO_P0_CTRL, + .gpio_mask = 0x01, + .inverted = 1, + }, + { + .role = EM28XX_LED_ILLUMINATION, + .gpio_reg = EM2874_R80_GPIO_P0_CTRL, + .gpio_mask = 0x40, + .inverted = 1, + }, + {-1, 0, 0, 0}, +}; + /* * Board definitions */ @@ -2057,6 +2107,24 @@ struct em28xx_board em28xx_boards[] = { .tuner_gpio = default_tuner_gpio, .def_i2c_bus = 1, }, + /* 1ae7:9003/9004 SpeedLink Vicious And Devine Laplace webcam + * Empia EM2765 + OmniVision OV2640 */ + [EM2765_BOARD_SPEEDLINK_VAD_LAPLACE] = { + .name = "SpeedLink Vicious And Devine Laplace webcam", + .xclk = EM28XX_XCLK_FREQUENCY_24MHZ, + .i2c_speed = EM28XX_I2C_CLK_WAIT_ENABLE | + EM28XX_I2C_FREQ_100_KHZ, + .def_i2c_bus = 1, + .tuner_type = TUNER_ABSENT, + .is_webcam = 1, + .input = { { + .type = EM28XX_VMUX_COMPOSITE1, + .amux = EM28XX_AMUX_VIDEO, + .gpio = speedlink_vad_laplace_reg_seq, + } }, + .buttons = speedlink_vad_laplace_buttons, + .leds = speedlink_vad_laplace_leds, + }, }; const unsigned int em28xx_bcount = ARRAY_SIZE(em28xx_boards); @@ -2222,6 +2290,10 @@ struct usb_device_id em28xx_id_table[] = { .driver_info = EM2884_BOARD_PCTV_520E }, { USB_DEVICE(0x1b80, 0xe1cc), .driver_info = EM2874_BOARD_DELOCK_61959 }, + { USB_DEVICE(0x1ae7, 0x9003), + .driver_info = EM2765_BOARD_SPEEDLINK_VAD_LAPLACE }, + { USB_DEVICE(0x1ae7, 0x9004), + .driver_info = EM2765_BOARD_SPEEDLINK_VAD_LAPLACE }, { }, }; MODULE_DEVICE_TABLE(usb, em28xx_id_table); diff --git a/drivers/media/usb/em28xx/em28xx.h b/drivers/media/usb/em28xx/em28xx.h index 43e2968..6e26fba 100644 --- a/drivers/media/usb/em28xx/em28xx.h +++ b/drivers/media/usb/em28xx/em28xx.h @@ -132,6 +132,7 @@ #define EM2884_BOARD_C3TECH_DIGITAL_DUO 88 #define EM2874_BOARD_DELOCK_61959 89 #define EM2874_BOARD_KWORLD_UB435Q_V2 90 +#define EM2765_BOARD_SPEEDLINK_VAD_LAPLACE 91 /* Limits minimum and default number of buffers */ #define EM28XX_MIN_BUF 4 -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
