Hello,
I'm working again on PXA27x keyboard support since I'd like to add
backlight support.
Since my hardware doesn't support "direct interface" but only "matrix
scan" what I can do is to integrate as much possible of the code of
your patch into the new driver so if someone has a mainstone can do an
easy port.
It could be acceptable?
Ciao,
Rodolfo

Hello, here my last patch for the PXA27x keyboard support updated to

Machines should call the driver with the following code:

}, { /* row 1 */
KEY_F2,
KEY_F3,
KEY_F4,
-1,
}, { /* row 2 */
KEY_UP,
KEY_LEFT,
KEY_RIGHT,
-1,
}, { /* row 3 */
KEY_DOWN,
-1,
-1,

},
},

};

Hi All!
I just made the AT91RM9200-EK board and successfully place the Uboot and
Linux2.4
But now I want to go for Linux 2.6 version and also I successfully compiled
the Linux 2.6 version and
Now I am trying to download into the board but I amgetting following error
you can see at the last two lines
Anyone can help me out to solve this problem.
I am just attaching whole procees after Reset the board It starts

Hello, here my last patch for the PXA27x keyboard support updated to

Hello, here my last patch for the PXA27x keyboard support updated to
linux-2.6.21-rc2.
I added power management support (suspend/resume code).
Machines should call the driver with the following code:
static struct pxa27x_keyboard_platform_data wwpc1100_kbd = {
.nr_rows = 4,
.nr_cols = 4,
.keycodes = {
{
/* row 0 */
KEY_ESC,
KEY_ENTER,
KEY_F1,
-1,
}, { /* row 1 */
KEY_F2,
KEY_F3,

The patch has bunch of issues that are hard to list because it was sent as
an attachment... Examples are: REL_WHEEL does not belong to evbit, using
input_free_device() is not allowed after input_unregister_device(), etc.
I tried to fix everything I notoiced; if you could try the patch below
and verify that it still works I will apply it to teh input tree.
Thanks.
