Dear,
I using the linux-2.6.29 with tsc2007 device.
It's GPIO 181 for PENIRQ with TSC2007.
so,
To configure the MUX_MODE4 that GPIO_181 connect PENIRQ with TSC2007,
please, refer to the below:
1. board-omap3evm.c
omap_cfg_reg(TSC2007_GPIO181);
2. mux.c
/* TSC2007 */
MUX_CFG_34XX("TSC2007_GPIO181", 0x1dc, OMAP34XX_MUX_MODE4 |
OMAP34XX_PIN_INPUT_PULLUP)
but,
root@omap3evm:~# cat /proc/interrupts
CPU0
11: 0 INTC prcm
12: 0 INTC DMA
24: 0 INTC Omap 3 Camera ISP
25: 0 INTC OMAP DSS
37: 2459 INTC gp timer
56: 3 INTC i2c_omap
57: 0 INTC i2c_omap
61: 0 INTC i2c_omap
72: 127 INTC serial idle, serial
73: 1 INTC serial idle
74: 1 INTC serial idle
336: 4243 GPIO eth0
341: 0 GPIO tsc2007
As you know, interrupt count 0.
To confiure GPIO MUX MODE4, Is it right?
please let me advice..
thanks.
