Alexander Aring 57c1bc7ea8 at86rf230: support edge triggered irq ... This patch adds support for edge triggered irq types. We remove the locking for irq resources by enable/disable irq and allocate directly some heap buffer at isr. We have still a enable/disable irq path but this is for level-triggered irq's which need to be disabled until spi_async clear the irq line. There is usually a little race condition between "irq line cleared" and "enable_irq". When in this time a edge triggered irq arrived, we will not recognize this interrupt. This case can't happend at at86rf230. The reason is that we unmask TRX_END irq's only which indicates a transmit or receive completion, which depends on the current state. On Transmit: TRX_END arrived and transceiver is in TX_ARET_ON state again, in this state no other TRX_END can happen until we leave the state. On Receive: This is protected with the RX_SAFE_MODE bit which leaves the transceiver in RX_AACK_BUSY until we readed the framebuffer. In this state no other TRX_END can happen. Tested with RPi where I first detected issues between edge/level irq's.
