It uses gpiolib and provides both fast inline operations when the gpio is a compile time constant and slower outline operations dispatched via gpiolib when the gpio is a variable. There are also hooks for implementing pin multiplexing but that part isn't finished yet. The major difference with the previous version is the move to a per-platform setup code as suggested by Greg Ungerer <gerg@snapgear.com>. Additionally, it fixes the definition of the TIMER gpio pins in the 5271 (thanks to Richard Retanubun <RichardRetanubun@ruggedcom.com>). ^ permalink raw reply [flat|nested] 17+ messages in thread
