TCA8418 with OMAPl138

Hello All,

I am following the below post to port TCA8418 to OMAPl138 EVM. 

http://e2e.ti.com/support/interface/etc_interface/f/390/p/202938/757229.aspx#757229

I am able to successfully interface on board TCA6416 to OMAP. Now omap is able to read states of the switches. Similar thing I am trying to do for 8418 matrix driver interfaced with 4*4 kepad to same I2C channel. 

As there is no support in 2.6 linux kenrel I checked out tca8418_keypad.c / .h files. Now I am trying to edit platform file (da850_omapl138) to add device TCA 8418. I don't know the basics of editing platform file so I was following the procedure given in above link. But that code is not working and I am getting errors in board file while building the kernel.

#include <linux/input/tca8418_keypad.h>
...
/* KEY(row, col, val) */
static uint32_t tca8418_km_data[] = {
    KEY(0, 0, KEY_LEFT),
    KEY(0, 1, KEY_DOWN),
    KEY(0, 2, KEY_ENTER),
    KEY(0, 3, KEY_M),

    KEY(1, 0, KEY_RIGHT),
    KEY(1, 1, KEY_UP),
    KEY(1, 2, KEY_I),
    KEY(1, 3, KEY_N),

    KEY(2, 0, KEY_A),
    KEY(2, 1, KEY_E),
    KEY(2, 2, KEY_J),
    KEY(2, 3, KEY_O),

    KEY(3, 0, KEY_B),
    KEY(3, 1, KEY_F),
    KEY(3, 2, KEY_K),
    KEY(3, 3, KEY_P)
};

static const struct matrix_keymap_data tca8418_mkdata[] = {
    .keymap            = tca8418_km_data,
    .keymap_size        = ARRAY_SIZE(tca8418_km_data),
};

static struct tca8418_keypad_platform_data tca8418_pdata = {
    .keymap_data = &tca8418_mkdata;
    .rows = 4;
    .cols = 4;
    .rep = 1;         /* Just a guess */
    .irq_is_gpio = 0; /* Just a guess */
};

static struct i2c_board_info am335x_i2c_boardinfo2[] = {
    {
        I2C_BOARD_INFO(TCA8418_NAME, TCA8418_I2C_ADDR),
        .platform_data = &tca8418_pdata,
    },
};

So in  tca8418_mkdata structure initialization code I am getting  above error. Could you please guide me in this aspect. Also is there any TI link for writing board file ??

Thanks in advance !!!
