Inter driver communication

Hi,

  1. I have a GPIO interrupt. I implemented this in the gpio-keys driver. Once this interrupt has occurred it should notify another device driver. It is a one-time requirement. It will be completed within booting time. How could implement this communication?

Regards

Hi mathew_k_t

if this should be done before launching operating system, seems

writing some flag to reserved mamory space would be suitable solution.

Best regards
igor
