In arch/arm/mach-s3c2440/mach_gta02.c there's this:
static struct spi_board_info gta02_spi_board_info[] = {
{
.modalias = "jbt6k74",
/* platform_data */
.platform_data = &jbt6k74_pdata,
/* controller_data */
/* irq */
.max_speed_hz = 10 * 1000 * 1000,
.bus_num = 2,
/* chip_select */
},
};
it means reduce the max_speed_hz from 10MHz to say 1MHz see if it
impacts it I guess.
