    OMAP4: 4430SDP: Add panel support to board file · 12595d46
    Tomi Valkeinen authored
    4430SDP has two Taal DSI panels, connected to DSI 1 and DSI 2 modules.
    The panels use a common PWM backlight, which will be implemented later
    when the PWM driver has been improved to support the backlight.
    
    Until the PWM driver has been improved, the following hack added to
    arch/arm/mach-omap2/board-4430sdp.c can be used to set the backlight to
    max:
    
    static int omap_4430sdp_hack_backlight(void)
    {
           twl_i2c_write_u8(TWL_MODULE_PWM, 0x7f, LED_PWM2OFF);
           twl_i2c_write_u8(TWL_MODULE_PWM, 0x7f, LED_PWM2ON);
           twl_i2c_write_u8(TWL6030_MODULE_ID1, 0x30, TWL6030_TOGGLE3);
           return 0;
    }
    late_initcall(omap_4430sdp_hack_backlight);
