I am starting work on porting our drivers from MV kernel to the git kernel, and getting a lot of warnings like:
warning: passing argument 1 of '__typesafe_io' makes integer from pointer without a cast Which comes from source like: u32 tmpreg; tmpreg = inl(GPIO_DIR45); We have our own header with lots of lines like this (inspired by drivers in the beta DM355 SDK): #define GPIO_DIR45 IO_ADDRESS( DAVINCI_GPIO_BASE + 0x60 ) Now, I'm pretty sure the we shouldn't be doing this for portability and so on, and should be getting these addresses in some platform-independent way, but for now It Works so I don't want to fix it. I would however like a clue on the right way to fix these warnings and do the kind of accesses I'm trying to do. There are many similar-looking macros and functions available: inl(), insl(), __raw_readl() and I don't know which I should be using, or if I should be passing around u32 "addresses" or __iomem pointers (maybe the IO_ADDRESS() should go?). Had a look around for documentation but not found anything too useful. Thanks, -- Jon Povey [email protected] Racelogic is a limited company registered in England. Registered number 2743719 .
