Hi folks, we've got lots of cases, where ->request_port() / ->release_port() are just (request|release)_mem_region calls, where the parameter values are practicall known after the device is initialized (*1). The only preparation needed for that is changing the individual drivers to initialize mapsize field on probing (*2). I see two practical options for that: a) introduce generic helpers, which are assigned as driver callbacks instead of the currently used driver specific ones. b) introduce a flag which tells the serial core to do that. What's your oppinion on that ? If you like, I can prepare some patches and post them here. --mtx *1) this also can be done w/ 8250, even though currently an extra function is called to compute the io size - I've already sent a patch for that some time ago. *2) already sent patches for that, a while go. -- Enrico Weigelt, metux IT consult Free software and Linux embedded engineering info@xxxxxxxxx -- +49-151-27565287
