git and touch screen

Hi all I am using linux davinci (33bd223c). my embedded card is da830 and i have a touch screen on it - TS2046. I found a driver on the net - (two files - TS2046.c TS2046.h , and some changes to the config and makefile). I know that the board is connected to the touch screen via spi. to be accurate - SPI1. Despite all of this, i dont have in the /arch/arm/mach-davinci/board-da830-evm.c the structs that include the spi and the touch screen. i saw in the internet something like that, that i think that need to be added to this code source:

static struct spi_board_info da8xx_spi_board_info1[] = {
    [0] = {
        .modalias = "tsc2046_ts",
        .platform_data = &tsc2046IPWR_place_holder,
        .controller_data = &tsc2046IPWR_spi_cfg,
        .mode = SPI_MODE_0,
        .irq = 0,
        .max_speed_hz = 2 * 1000 * 1000  ,
        .bus_num = 1,
        .chip_select = 2,
    },
};

Altough, my guess is, that that code is from montavista, and i use git. someone, please help..
