From: Bartosz Golaszewski <[email protected]> Modify the aintc driver to take all its configuration from the new config structure. Stop referencing davinci_soc_info in any way. Move the declaration for davinci_aintc_init() to irq-davinci-aintc.h and make it take the new config structure as parameter. Convert all users to the new version.
