Jesus Sanchez-Palencia d70f67cd60 galileo: Add PIT driver ... This patch adds a driver for the 8254 Programmable Interrupt Timer (PIT). The driver introduced by this patch programs the PIT to generate interrupt periodically. The interrupt frequency can be configured by the user. On each PIT interrupt, a callback configured by the user is called. As expected, that callback is executed in interrupt context so the user should be aware of what it is not supposed to do (e.g. to call blocking functions). Issues marked as FIXME are all related to missing APIs on the PIC driver so they will be addressed by a future commit.		2015-12-21 08:06:14 -02:00
