@We need an info on enabling interrupt, Till now we were polling the user mode status registers to know LOCK and UNLOCK of signals, We want to switch to interrupt mode. I have gone through the link@ https://ez.analog.com/docs/DOC-7555
And followed the configuration for interrupt. We are not getting interrupt, need your help to know whether we are missing anything here. I used omapconf tool to set the registers and verified the register values after writing.
Interestingly interrupt status registers are updated whenever i toggle camera.
I setup interrupt handler and I am able to see that in /proc/interrupts and I used below instructions to configure
omapconf i2c write 0 0x21 0x04 0x07
omapconf i2c write 0 0x21 0x0E 0x20
omapconf i2c write 0 0x21 0x40 0xD1
omapconf i2c write 0 0x21 0x44 0x03
omapconf i2c write 0 0x21 0x43 0x03
omapconf i2c write 0 0x21 0x0E 0x00
For clearing interrupt
omapconf i2c write 0 0x21 0x0E 0x20
omapconf i2c write 0 0x21 0x43 0x03
omapconf i2c write 0 0x21 0x0E 0x00
Thanks
